Rather than defending yourself from an incoming attack, you welcome it, stretching your arms wide open. The incoming attack automatically lands as a critical hit. If it was already a critical hit, nothing changes.
Letting the very cells where you were attacked wither away, and instantaneously blooming new ones to invigorate you, you feel a newfound strength brewing within you. After the hit lands, granted you are still at 1 hit point or higher, you immediately gain one action. Attacks done during this action are automatically critical hits, and do an extra 2d6 necrotic damage unless the target is undead or a fiend.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the necrotic damage increases by 1d6 for each slot level above 3rd.
