Grung Monk (5e Creature)
From D&D Wiki
Small humanoid (grung), lawful evil
Amphibious. The grung can breathe air and water.
Poisonous Skin. Any creature that grapples the grung or otherwise comes into direct contact with the grung's skin must succeed on a DC 13 Constitution saving throw or become poisoned for 1 minute. A poisoned creature no longer in direct contact with the grung can repeat the saving throw at the end of each its turns, ending the effect on itself on a success.
Standing Leap. The grung's long jump is up to 35 feet and its high jump is up to 15 feet, with or without a running start.
Multiattack. The grung makes three unarmed strikes.
Unarmed Strike. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) slashing damage.
Head Leap. If a jump would cause the grung to land in a hostile creature's space, they may use their reaction to leap an additional 15 feet, that does not count towards their movement speed. When doing so, the target must succeed on a DC 13 Strength saving throw or be knocked prone.
Deflect Missiles. In response to being hit by a ranged weapon attack, the grung deflects the missile. The damage it takes from the attack is reduced by 1d10 + 3. If the damage is reduced to 0, the grung catches the missile if it's small enough to hold in one hand.
