Dark Bargain

The spell binds incoming energy, preventing it from effecting you for a brief time, but amplifying its effects against you. You delay the effect of the triggering harmful spell or magical effect until the end of your next turn. This triggers after any attack rolls have been rolled, but before any saving throws, damage rolls, or effects are determined. The effects of the spell or effect are delayed for you and you only.

When the spell ends, the delayed harmful magic takes effect on you, extracting a terrible toll. All damage dice are treated as having rolled their maximum value, and you are treated as having failed all saving throws associated with the effect. You are treated as the appropriate target for the delayed effects. You are treated as having the most detrimental physical condition for the spell (for example, you would be treated as having less than 150 HP if targeted by Power Word Stun). All damage you take ignores all immunities and resistances you may possess (still applying to vulnerabilities), and nothing can prevent this delayed damage from affecting you.

You can be affected by only one Dark Bargain spell at a time. If you cast this spell while you are already under the effects of a previous Dark Bargain, the previous spell effect ends and you immediately take the damage and/or effects it had delayed.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the duration of the delay increases by one additional round.
