Exalted Ruin

You mark a creature you can see with divine radiance laced with dark resonance. At the start of each of the target's turns, all of their attribute bonuses increase by 2 (cumulative, stacking to +6 by the third round). At the end of their third turn, the accumulated power collapses - the target takes 60 Psychic damage and loses all gained bonuses. The effect cannot be ended early, dispelled, or resisted. The crash damage can be mitigated through resistances, healing spells, damage reduction, and other protective abilities.
