Magmatic Touch

Making a melee spell attack by touching a creature, you deliver a searing strike that deals 1d8 fire damage. The creature has disadvantage on its next attack.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8). Upon reaching 5th level, it can be cast as an Attack action, and at 11th level the damage becomes incinerating.
