Feat: Resounding Cascade

The magical reinforcement from your Arcane Cascade extends to nearby allies. While you're in Arcane Cascade stance, you grant its extra damage and resistance in an aura affecting all allies in a 5-foot emanation. This uses only the base values of your stance; 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.
