Vampiric Blade

As part of the action used to cast this spell, you must make a melee attack against one creature within the spell's range, otherwise the spell fails.  On a hit, the target suffers the attack's normal effects, and you absorb part of the creature's life essence.  The creature takes an additional 1 point of necrotic damage, and you regain hit points equal to the necrotic damage the creature suffers.  This spell's damage increases when you reach higher levels.

At Higher Levels: This spell's necrotic damage increases by 2 when you reach 5th level (3), 11th level (5), and 17th level (7).
