Fortify Lifeblood

Your ability to manipulate blood allows you to infuse yourself with it, even using the blood of others to renew your own vitality. When a creature you can see within range dies, regain 2d4+ your spellcasting modifier of hit points. This does not work for undead or constructs. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can add 1d4 healing for each slot level above 1st.
