1st-level Spell: Rotting Curse

Sorcery (Necromancy)

You inflict a curse of decay on a creature within range, causing it to begin to rot. For the duration, every time the target takes damage, it takes an additional 1d4 necrotic damage, and the effect of any healing it receives is halved.
The target also has disadvantage on any Charisma checks for social interaction for the duration.
