Bloodprint

You willingly spill your own blood to make a creature in close range more vulnerable.

You remove 1 remaining hit die and mark a creature within 10 feet of you. The marked creature appears to be constantly leaking blood, and takes -2 to their AC. The creature is marked for 5 rounds.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the marked creature also gains the effect of the slow spell.
