(take when another creature within range takes damage)
You absorb a measure of a creature's suffering and escaping vital essence. Expend and roll on Hit Die. You regain a number of hit points equal to the number rolled plus your spellcasting ability modifier.
If the creature took damage from a critical hit, double the number of hit points you regain.
At Higher levels: When you cast this spell using a spell slot of 2nd level or higher, you can expend one additional Hit Die for each slot level above 1st.
You sting the eyes of a creature attacking you. The target must make a Constitution saving throw (a creature with blindsight or immunity to the blinded condition succeeds automatically). On a failed save, the target is blinded until the end of the turn. On a successful save, it must subtract 1d4 from the triggering attack roll. The target automatically succeeds on its saves against your subsequent casting of this spell for 24 hours.
