Blutgeschosse (Haemocraft)

Choose up to 4 hit die, sacrificing that amount amount of HP as the material component of the spell. For each hit die sacrificed, you imbue your blood into a piece of ammunition.

When you make a ranged attack roll with one of these pieces of ammunition, your attacks ignore half and 3/4 cover and are made with advantage, as you mentally control their movement through your blood.

At Higher Levels. When you cast this spell, the maximum amount of hit die that can be sacrificed increases by 1 for each level above 3rd.
