Blood Drain

Choose a creature that you can see within range. A surge of negative energy washes through the creature, causing it to lose 1d6 hit points and you gain that much. This spell has no effect on constructs or undead.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
