A player using a model with the Master of the Black Arts power can re-roll one of the dice when it is determining the strength of the Winds of Magic in each of your Magic phases.
Model on foot only. The model gains the Ethereal special rule. However, it may not join non-Ethereal units or take any magic items.
The model and all friendly Wizards within 12" gain +1 to cast spells from the Lore of Necromancy.
When casting Raise Dead or any augment spell from the Lore of Necromancy, the model may re-roll all the initial casting dice (unless they have rolled a Miscast).
Once per Magic phase, the model can re-roll one of the dice rolled to cast a spell. This can be used to negate a Miscast result or could cause an Ultimate Power result.
The model adds +D3 to the number of Wounds healed whenever it successfully casts Invocation of Nehek, following its normal restrictions.
The model has the Loremaster special rule.
The model adds +6" to the range of all their spells.
