Resounding Cascade

Trigger You use Arcane Cascade.

When you enter your Arcane Cascade, you disperse the magical reinforcement to nearby allies. You grant the extra damage of Arcane Cascade in an aura affecting all allies in a 5-foot area. This uses only the base damage of the stance, based on the ally's weapon specialization; it doesn't use any increase you get from bonuses, the Laughing Shadow hybrid study, or the like.

As normal for duplicate effects, multiple Arcane Cascades affecting the same creature aren't cumulative.
