Vampiric Strike

You empower your weapon causing it to sink deeper into the enemy's flesh as it funnels their essence into you. As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and the target takes an extra 2d6 necrotic damage and you heal for half the necrotic damage dealt.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every level above 2nd.
