Emerald Claw

Baleful emerald energy wreaths your hand to disrupt the life and body of a creature you try to touch. Make a melee spell attack against the target. You have advantage on the attack roll if the target is not wearing armor, or is wearing armor made of biological materials (ex. leather). On a hit, the target takes 1d6 necrotic damage, and is poisoned until the start of its next turn.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
