Denier of Destruction

Requirements You have a spell prepared and you aren't to the source of the damage.

Trigger Any ally within 30 feet that you can heal with your heal spell would take damage from an attack or effect from a source you can observe.

You can manipulate the same energies that the aeon orbs use to sustain life. You cast heal on the triggering target. Instead of its normal effects, the heal spell reduces the triggering damage by an amount equal to the Hit Points a 1-action heal spell of that rank would have recovered. As usual, if this reduces the damage to 0, it might also remove additional effects of the triggering attack, such as injury poisons.
