Drain Flesh

You enter a trance which allows you to drain the flesh of the living that you can see. You cannot move whilst casting and moving will break the spell. On a hit, the target takes 1d6 necrotic damage, and you regain hit points equal to half the amount of necrotic damage dealt. No hit roll is required if on the next turn if the spell is not broken. This lasts for a minute (10 turns).

During this time you are vulnerable and any melee attacks on you will have an advantage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 rounded down above 3rd. (Level 4 -5 will be 2d6, Level 6 - 9 will be 3d6 etc.) The range of the spell also increases by 10 ft per level.
