Bloodrite Smite

The next time you hit a creature with a weapon attack, you can rip the blood from a creature's veins just for a moment as your weapon becomes covered with a mixture of dark crimson and necrotic energy. The attack deals an extra 2d6 necrotic damage to the target. You then rend the blood from the enemy, healing for the amount of damage the creature takes.

Additionally the creature must make a Constitution saving throw or be stunned until the beginning of their next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 1d6 for each slot level above 1st.
