Summon Dread Maw is a direct damage spell. Place the small round template anywhere within 18" of the caster. Roll the artillery dice and the scatter dice. Unless a Hit! is rolled, move the template the distance shown on the artillery dice, in the direction indicated on the scatter dice.
If a misfire is rolled, centre the template on the caster and roll a scatter dice and a D6. The template moves the number of inches equal to the result of the D6, in the direction shown on the scatter dice. If you roll a Hit!, use the little arrow shown on the Hit! symbol.
Once the final position of the template is determined, all models under the template must take an Initiative test. Models that pass the test suffer a Strength 3 Hit. Models that fail the test suffer a Strength 5 hit with the Killing Blow and Multiple Wounds (D3) special rules.
