Blue Slaad

The slaad has Advantage on saving throws against spells and other magical effects.

The slaad regains 10 Hit Points at the start of each of its turns if it has at least 1 Hit Point.

The slaad makes three Mutating Claw attacks.

Melee Attack Roll: +8, reach 10 ft. Hit: 12 (2d6 + 5) Slashing damage plus 3 (1d6) Poison damage. If the target is a Humanoid not cursed by a slaad, it is subjected to the following effect. Constitution Saving Throw: DC 15. Failure: The target is cursed. The cursed target can't regain Hit Points, and its Hit Point maximum decreases by 10 (3d6) after every 24 hours and doesn't return to normal after finishing a Long Rest. If the curse reduces the target's Hit Point maximum to 0, the curse ends, and instead of dying, the target instantly transforms into a Red Slaad or, if it can cast spells of level 3 or higher, a Green Slaad. Only a Wish spell can reverse this transformation.
