Piercing is a red spell modifier under the Offense tree that allows the user's spells to pass through and affect more than one mob per cast.
For every instance of the piercing modifier in the spell, projectile spells will pass through and affect one more mob.
- Although the Arcane Compendium says that 2 extra pierces are added per modifier, each modifier only allows for one more penetration each. Likewise, the Arcane Compendium states that the Wave spell shape is modified by Piercing, but that is also incorrect.
- Piercing may be used for harmful and helpful spells alike
