Festering Aura. Any creature, other than you, that starts its turn within 5 feet of the abomination must succeed on a constitution saving throw against your spell DC or be poisoned until the start of its next turn.

Multiattack. The abomination makes two melee attacks.

Rotting Claw. Melee Weapon Attack: +3 + (your proficiency bonus) to hit, reach 5 ft., one target. Hit: 1d6 + 3 + (your proficiency bonus) slashing damage. If the target is poisoned it must succeed on a constitution saving throw against your spell DC or be paralyzed until the end of its next turn.

Vomit (Recharge 6). The abomination vomits in a 10-feet line that is 5 feet wide. Each creature in that line must make a saving throw against your spell DC. On a failure it takes (your proficiency bonus) x d10 poison damage and is poisoned for 1 minute. On a success it takes half damage and is not poisoned. A creature poisoned by this ability can repeat the saving throw at the end of each of its turns, on a success it is no longer poisoned.
