Cholkrin

Multi-attack. The Cholkrin can make three attacks, One with its stinger, and Two with its quills. 

Stinger. Melee Weapon Attack: +6 to hit, reach 10 ft., 1 target. Hit: 7 (2d4 + 3) [piercing] damage. On a hit, the creature must make a DC 14 Constitution save. On a failure the creature takes 3d8 [poison] damage and is poisoned for 1 minute. If the creature fails the save by more than 5, they are also paralyzed. On a success, the creature takes half damage and is not poisoned.

Quill. RangedWeapon Attack: +6 to hit, range 25/50 ft., 1 target. Hit: 9 (1d10 + 3) [piercing] damage.

Wild Consumption 1/day. The Cholkrin feeds on magical energy and is heavily drawn to the arcane. If a creature casts a spell within 60ft of the Cholkrin, the Cholkrin may use its reaction to negate and consume the spell. The spellcaster must make a Charisma saving throw (10+spell level), or have its spell negated. If the spell is negated the Cholkrin gains 1d8 hit points for each level of the spell. A Cholkrin may use this ability until it succeeds, otherwise, it must wait until the next day.
