If a Warboss is your Army General, then once per game he may call a Waaagh! The Waaagh! may only be called if the Warboss first declares a charge, and must be announced immediately after making the charge declaration, before any charge reaction takes place. In the turn a Waaagh! is called, every combat involving Orcs (of any type) in the army adds +1 to its combat resolution for the rest of the player turn. The General himself, and any unit he joins, adds +D3 to their combat resolution instead. In addition, every unit that fails their Animosity test this turn add their rank bonus to the result rolled on the Animosity table.

Models wearing Warpaint gain the Ward Save (6+) special rule.

At the start of each round of close combat, models with this special rule can choose which of their weapons (including hand weapon and shield) they wish to fight with. If a Black Orc character has a magic weapon, he loses the benefit of this special rule.

If a Black Orc character is in a unit that fails an Animosity test, he immediately inflicts D6 hits at his base Strength on his unit, distributed as shooting attacks. After removing casualties, the unit is treated as if the Animosity test was passed. These hits cannot be allocated to the Black Orc character, and do not cause a Panic test.

Each time they attempt to cast a spell, after the casting dice have been rolled a Night Goblin Shaman may eat a Magic Mushroom. This adds D6 to the casting result. This dice does not count as a power dice, and cannot contribute to Unlimited Power. However, if you roll a 1 on this dice you must roll a further D6. On a roll of 4+ nothing else happens, but on a roll of 1-3 the mushroom was poisonous, and the Shaman suffers a wound with no armour saves allowed, and the spell automatically fails.

Forest Goblin Shamans may re-roll one dice when casting spells. However, any time they Miscast, they will also count as having failed a Stupidity test (if they survive).

Any Orc unit joined by a Warchanter may re-roll 1's To Hit and To Wound in close combat.

A mount with this special rule receives the Strength Bonus (2) special rule during the turn in which it charged into combat.

Unlike other Cavalry, Spider Riders do not have to dismount before assaulting a building, meaning the Giant Spiders are allowed to attack during the assault. Each Spider Rider and his mount count as a single model when determining the number of models that fight in a building assault. Note that Spider Riders still cannot garrison a building.

Models with this rule treat ungarrisoned buildings as open terrain for the purposes of movement. They may not finish their movement inside or on top of an ungarrisoned building – they can pass over obstructions of this kind, but they cannot linger.

The only unit a Night Goblin character mounted on a Great Cave Squig is allowed to join is a Squig Hopper unit.

A unit of Savage Orcs may be upgraded to include Big Stabbas. This is represented by including one or more Big Stabba models in the unit. A Big Stabba is mounted on two Infantry bases and must be placed to cover both the first and second rank of the unit, but is otherwise equipped like the rest of the unit. Each Big Stabba model causes Impact Hits (D3) with the Multiple Wounds (D3) special rule. Big Stabbas are always the last models to be removed as casualties; the weapons are picked up by other Savage Orcs in the unit (excluding any Command Group models) should they be slain.

A Goblin Jester is placed in the front rank of the unit he is bought for and may never leave the unit.

Goblins are always encouraged by the presence of a Jester and any unit gains a +1 bonus to their Leadership characteristic and ignores Animosity as long as the Jester is alive.

On the downside however, Goblins are always so distracted by Jesters that they are subject to the Stupidity special rule.

As Jesters are so energetic in battle it is almost impossible to hit the blighter in melee. Enemies must re-roll successful To Hit rolls against them in close combat.

At the start of each round of close combat in which a Goblin Jester is involved, roll a dice and consult the table below:

A unit of Night Goblins may be upgraded to include one or more models of Netters. This is represented by including one or more Netter models in the unit. Netters are equipped and may fight like the rest of the unit. At the start of each round of close combat, the Netters must attempt to entangle one of the units they are fighting in their front arc. Roll a D3 for each of the first three ranks of 5 or more models in your unit; the result is the number of enemy models has become entangled (distributed as hits from shooting, but only affecting models that are allowed to strike). However, for each natural 1 rolled on these dice, the Netters have managed to cast the nets amongst their own ranks and entangle a member of their own unit instead. A model that has been entangled suffers a -1 penalty to their Attacks (this applies to both the rider and the mount) until the end of the close combat round.

Twackwheezer Puffshrooms replace the Fanatic's normal Strength 5 Hits. All models Hit must pass a Toughness test or suffer a Wound which Ignores Armour Saves. This has no effect on Animated Constructs. In addition, all models within 6" of a Fanatic with this upgrade count as being in soft cover.

Fanatics cannot be charged, but models can move into contact with them. Any unit that does so takes 2D6 Strength 5 Armour Piercing (1) hits. The Fanatic model is then removed, and the unit may carry on with its move.

Fanatics deploy following the rules for Hidden models. However, they are not revealed like other Hidden models, but instead follow the rules below.

A Fanatic is removed immediately as a casualty when:

• It contacts a piece of terrain of any kind that's not open ground.

• It contacts another Fanatic (both Fanatics are removed).

• It moves off a table edge.

• It rolls a double for movement. This does not apply in the turn of release and represents the Fanatic being choked by the chain, tripping or other comical, yet fatal, mishaps.

• Any unit moves into contact with the Fanatic.

Fanatics must be released when an enemy unit comes to within 8" of the concealing unit's Line of Sight. The moving unit stops immediately (fliers land). Once the Fanatic's movement has been resolved, the unit can continue moving if the controlling player wishes, although chargers must complete their charge unless panicked. When a Fanatic is released, you may choose the direction in which it travels, and the point on the concealing unit from which it starts. Fanatics move 2D6" using the rules for Random Movement, measured from the base of its unit. After release, Fanatics are treated as individual units. In your subsequent turns they must move in the Compulsory Moves subphase using the Random Movement special rule, but they always move in a random direction.

If a Fanatic's move would bring it into contact with another unit, then he moves through rather than stopping. If the Fanatic's move would end within a unit, then he automatically bounces through it – place the Fanatic model 1" beyond the unit, in the direction he was moving. When a Fanatic moves through any unit it inflicts D6 Strength 5 Armour Piercing (1) hits.

Each Snotling base can make a single shooting attack in its Shooting phases, and as a stand and shoot reaction. An Explodin' Spore is a Throwing Weapon, hitting automatically with the Ignores Armour Saves special rule.

Orc Brutes may re-roll failed To Hit rolls against Monstrous Infantry, Monstrous Beasts, Monstrous Cavalry and Monsters.

At the end of any Close Combat phase in which a unit of Nasty Skulkers take part, they may choose to use their smoke bombs. On a 4+, the unit may disengage the combat by making a flee move. If they do so, the enemy cannot pursue them and they will rally automatically in their next turn.

Nasty Skulkers have the Always Strikes First and Armour Piercing (1) special rules in any turn they successfully charge an enemy in the flank or rear.

The models in a unit of Night Goblin Squig Hunters may be armed with number of different weapons. This is represented by including one or more models with that weapon in the unit. If the unit includes Nets the unit follows the rules for Netters (see Night Goblins). If the unit includes Clubs all models fight with +1 Strength in close combat. If the unit includes Prodders all models gain the Fight in Extra Ranks (1) special rule.

If the unit flees, or if at any time there are only Squigs left alive in the unit with no Herders, the Squigs go wild, biting at anything nearby. All units within 2D6" (friend and foe) immediately take D6 Strength 5 hits. For every 5 Cave Squigs remaining when the Squigs Go Wild, add +1 to the number of hits caused. After damage is resolved, the Squig Herd is removed in its entirety.

At the start of your movement phase, as long as it is not in close combat or fleeing, you can say that this unit is harvesting mooncap mushrooms. If you do so, it cannot move in that movement phase, but you can roll a D6. On a 2+, pick a friendly Night Goblin unit (of any type) within 6" of this unit. This unit gains the Frenzy special rule until the start of your next turn.

Sneaky Snufflers consist of a Night Goblin and a Snufflesquig mounted on the same base. They follow the split profile rules for Cavalry.

An Orc Bully counts as an extra crew member (and an extra wound) for the war machine, and is always the last model to be removed. Orc Bullies have the Choppas special rule. In addition, while the Bully is still alive, their unit gains the Size Matters special rule and is no longer subject to Fear Elves.

If the To Hit roll for a shooting attack made by a Spear Chukka is a 1 (before any modifiers are applied), then it misfires. Roll on the Stone Thrower Misfire Chart in the Warhammer rulebook and apply the result to the Spear Chukka.

River Trolls have the River Strider and Marsh Strider special rules. Additionally, enemies attempting to attack a River Troll in close combat suffer a -1 penalty on their To Hit rolls due to the stench and slime.

Stone Trolls have the Magic Resistance (2) and Natural Armour (5+) special rules.

Instead of attacking normally, the whole unit can choose to vomit on the enemy. Each model inflicts one automatic Strength 5 hit which Ignores Armour Saves.

The Doom Diver Catapult is a stone thrower, but because the Doom Diver has the ability to 'glide and guide' into a target, it has some additional rules, detailed here. Fire the Doom Diver Catapult as a Stone Thrower. However, no template is used. Instead, place the flying Doom Diver Goblin model on the target point, and then roll for scatter as you would for a stone thrower. After doing this, you may roll a D6 and move the Doom Diver Goblin model by that many inches in any direction. If any units are touched by the Doom Diver's base, then each must take D6 Strength 5 hits which Ignores Armour Saves.

Should the artillery dice roll a misfire, roll a D6 and consult the Doom Diver Misfire table, below.

A Pump Wagon fitted with flappas only has to take Dangerous Terrain tests if they end their move in Dangerous Terrain.

If a Pump Wagon has giant explodin' spores, the first set of Impact Hits it inflicts in the game Ignores Armour Saves.

If a Pump Wagon has an out-rigga then its Movement characteristic is increased to 3D6. Note that this means that if the crew decide to pump harder then you must roll 4D6 for the Pump Wagon's random movement.

If a Pump Wagon has a spiky roller then all its Impact Hits have +1 Strength.

Before moving a Pump Wagon you may declare that the crew are 'pumping harder'. If you do so, you must roll 3D6 for its Random Movement.

Any time a Pump Wagon rolls two or more l's for its movement, it will not move as normal but instead veers out of control. Re-roll the Random Movement distance (including the extra dice if you were 'pumping harder'), but this time the Pump Wagon will move in a random direction. If the re-rolled movement also includes two or more ls, then the Pump Wagon has crashed – remove it as a casualty. Otherwise, all Random Movement rules apply, except that a Pump Wagon halted by a friendly unit will inflict 2D6 Impact Hits on the unit that blocks its move.

Mangler Squigs are removed as a casualty when:

• They contact other Mangler Squigs (both Mangler Squigs are removed as casualties).

• They have gone crazy and rolled a triple for movement. This represents the Great Squigs ripping themselves to pieces or some other comic, yet fatal mishap.

• Any unit moves into contact with the Mangler Squigs – see the Force of Total Destruction rule.

Mangler Squigs cannot be charged, but models can move into contact with them. Any unit that moves into contact with Mangler Squigs takes 2D6 Strength 6 hits for moving into the Squigs and a further D6 Strength 6 hits due to the Mangler Squigs' death throes. The Mangler Squig model is then removed, and the unit may carry on with its move.

Mangler Squigs that make a Ker-Splat! attack Go Crazy, their Night Goblin crew being either pulped to death or too busy holding on to even attempt to control the Squigs' direction. Once Mangler Squigs have Gone Crazy they will move in a random direction when they move in the Compulsory Moves sub-phase.

If the Mangler Squigs' move would bring them into contact with another unit, then they move through rather than stopping. If the Mangler Squigs' move would end within a unit, then they automatically bounce through it – place the Mangler Squigs 1" beyond the unit, in the direction in which they were moving.

When Mangler Squigs move through a unit (friend or foe) they inflict 2D6 Strength 6 hits.

Mangler Squigs must take a Dangerous Terrain test if they move over any of the following types of terrain: Forests, Marshland, Obstacles or Mystical Monuments. If their move would take them into contact with a Building, Impassable Terrain or off a table edge then they must take a Dangerous Terrain test and will stop 1" short of the obstruction.

The Squig Gobba may fire in the Shooting Phase as long as as least one Night Goblin Tender remains and it is not in close combat. When firing the Squig Gobba, roll 3D6 and consult the table below:

The Squig Gobba cannot move after it has been deployed except pivoting on the spot. It may not pursue an enemy it defeats in combat. If the Squig Gobba breaks from combat, it is automatically destroyed.

When the Colossal Squig's Random Movement special rule brings it into contact with a unit, either friend or foe, it will attack it normally as if it were an enemy, and counts as charging that unit. This combat will continue until resolved normally. These appalling creatures are too dull-witted and hungry to care otherwise!

When a Colossal Squig is removed as a casualty, every model in base contact with it suffers an automatic Strength 3 hit.

Instead of attacking normally, this model can choose to vomit on the enemy. It inflicts D6 automatic Strength 6 hits which Ignores Armour Saves.

The Flinger is a Stone Thrower with the profile shown below. It can fire even if the Arachnarok Spider moves, but not if it marches.

Any unit hit by a Flinger is covered in a mass of sticky webs, and suffer -1 to its M, WS, BS, S and I until the end of its next turn. The Flinger does not use the Stone Thrower Misfire table – a misfire result simply means that the Flinger may not shoot this turn.

A Forest Goblin Great Shaman mounted on an Arachnarok Spider with a Catchweb Spidershrine has the Loremaster (Spells of da Spider God) special rule. In addition, he and any other friendly Wizard within 12" of the Arachnarok Spider adds +1 to their channelling attempts.

When fighting Monstrous Infantry, Monstrous Beasts, Monstrous Cavalry or Monsters; before rolling to hit, nominate one of the Arachnarok's attacks to be made with the Venom Surge, and roll it separately. This is a Poisoned Attack with the Multiple Wounds (D6) special rule.

If it is possible for a Rogue Idol to charge an enemy it must do so (however if multiple targets are within charge range, its player may pick which to attack). At the start of any turn that a Rogue Idol is not able to charge or is not already in combat, its player must roll a D6. On a roll of a 1 it must instead charge a friendly unit if one is available to charge, and a single round of combat is fought as normal, after which the Rogue Idol is pushed 1" back if the charged unit does not break. If no friendly units are available to charge the Rogue Idol bellows and stomps, but otherwise may do nothing this turn.

Enemies attempting to attack a Giant River Troll Hag in close combat suffer a -1 penalty to their To Hit rolls.

This is a Strength 3 Breath Weapon with the Ignores Armour Saves special rule. A unit that takes casualties from to this attack suffers -2 to its Leadership until the start of your next turn.

Unless she is within a water feature of any type (including rivers, marshes, swamps, etc), the Giant River Troll Hag has the Stupidity special rule. If the test is failed and there is one or more water features on the table, the Troll Hag moves towards the closest of these instead of straight forwards.

Gorbad must be army's General, and he also has the Hold Your Ground! ability like a Battle Standard. In addition, the range of Gorbad's Inspiring Presence and Hold Your Ground! Abilities is increased from 12" to 18". Note that you may not choose a separate Battle Standard in an army that includes Gorbad.

Friendly units within 18" of Gorbad that fail an Animosity test add Gorbad's current number of Wounds to their roll on the Animosity Table.

An Orc & Goblin army that includes Gorbad may upgrade any number of units of Orc Boyz and/or Orc Boar Boyz to Big 'Uns.

Any unit within range of Azhag's Inspiring Presence that fails an Animosity test must immediately re-roll the dice.

All friendly units within 12" of Gordrakk gain the Devastating Charge special rule.

Being Mork's current favourite, Wurrzag adds +1 to cast spells, and may re-roll miscast results.

Wurrzag's Warpaint gives him a Ward Save (5+).

Grimgor must always be accompanied by his grizzled Black Orc bodyguard, and may join no other unit. The Immortulz are a unit of Black Orcs with an additional +1 Weapon Skill. Grimgor must deploy with this unit and may not leave it. No other character may join the unit. As long as Grimgor is alive, the Immortulz have the Hatred special rule.

If your army includes Grimgor, he must be the Army General.

If your army includes Morglum, he must be the Army General.

As long as Grom is alive, all units in his army ignore the Fear Elves special rule.

If your army includes Grom, he must be the Army General. In addition, Grom would never tolerate the presence of anybody who might threaten his command. You may not include any Orc, Savage Orc or Black Orc Lords if Grom is your General. An army containing Grom must include at least one unit of Goblins.

This large chariot is pulled by three Giant Wolves and has scythed wheels. It has room to carry only Grom and Niblet.

Grom has the Waaagh! special rule. When Grom calls a Waaagh!, in addition to the units that would normally be affected, every unit of five or more Goblins, Goblin Wolf Riders, Night Goblins, Forest Goblins and Forest Goblin Spider Riders in the army adds +1 to its combat resolution for the rest of the player turn.

Niblet counts as the army's Battle Standard Bearer. Niblet is part of the chariot model and, although he can attack, he can never be engaged separately or issue or accept challenges.

Skarsnik and Gobbla are treated as a single infantry model with a single set of wounds. Gobbla's profile is used only when he attacks.

At the start of the game, before deployment, roll a D6 for each enemy unit. On a roll of 6, that unit has been delayed by a Wild Squig strike or some other happening. Affected units do not deploy as normal, but instead enter play as reinforcements in the Movement phase of their first turn.

Any friendly Night Goblin unit that chooses to flee as a charge reaction and subsequently rallies at the beginning of its next turn may reform as normal, but is then also free to move during the Remaining Moves sub-phase. The unit is also free to shoot as normal (but it always counts as having moved).

The Black Gobbo may re-roll all failed rolls To Hit when fighting Dwarfs. In addition, the Black Gobbo and any unit he accompanies are Stubborn when they are in base contact with any Dwarf.

Skragrott can always choose to re-roll any number of dice when determining how far the template from the Curse of da Bad Moon spell moves.

If Borgut is included in your army, then you may upgrade one additional units of Orc Boyz into Big 'Uns. Borgut must deploy and remain with this unit for the entirety of the battle.

If Borgut fights in a challenge, then at the beginning of the first Close Combat phase of the challenge, he can smash his thick Orc skull into the face of his opponent or any monstrous mount they may be riding. This is in addition to his normal attacks, and is resolved before any other attacks in the challenge. If this attack inflicts an unsaved Wound, the target is reduced to Weapon Skill 1 and gains the Always Strikes Last special rule for the rest of the Close Combat phase. If this mighty 'eadbutt kills his opponent, Borgut can still make his remaining attacks to calculate Overkill for the purposes of combat resolution.

If your army includes Grimgor, then you may never deploy Borgut further than 6" from him when setting up your army.

Badruk has the Killing Blow special rule. In addition, he causes a Killing Blow on the To Wound roll of a 5+ rather than a 6.

The Stinky Pelt grants Gitilla the Natural Armour (5+) special rule.

Da Howlerz are a unit of Goblin Wolf Riders with an additional +1 Ballistic Skill and the Quick to Fire special rule. Gitilla must set up with this unit and may not leave it. No other character may join the unit.

One use only. The Sting is a missile weapon with the following profile:

The Deff Creepers are a unit of Forest Goblin Spider Riders with the Ambushers, Devastating Charge and Hatred (Empire) special rules. In addition, they cause Fear in any turn that they successfully charge into combat. Snagla must set up with this unit and may not leave it. No other character may join the unit.
