Trigger A creature within range that you can see Casts a Spell.

Targets the spell cast by the triggering creature
You undermine the target spell, making it easier to defend against. You reduce the spell's level by 1, and targets of the spell gain a +2 status bonus to any saving throws, skill checks, AC, or DC against it.
You can't reduce the spell's level below its minimum. For example, a 5th-level
cone of cold would remain 5th-level, but a 5th-level
fireball would become 4th-level. Targets still gain all the other benefits, even if you don't reduce the spell's level.
