Blood Storm

You conjure a rain of blood in a 30ft-radius area centered on a point of your choice within range. Creatures in the area start bleeding abundantly as their blood is unable to coagulate. Every time they take bludgeoning, piercing or slashing damage, they lose an additional 1d6 hit points. Creatures immune to bludgeoning, piercing and slashing damage are immune to this effect.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the loss of hit points increase by 1d6 for each slot level above the 2nd.
