Spree Demon

This wild gnome’s shaggy hair is matted on one side with blood. It has razorlike claws, and its teeth are filed to points.   Gnomes who die while succumbing to vile, homicidal desires sometimes return as murderous, demonic creatures.

Features

Multiattack. The spree demon makes two claw attacks. If both attacks hit the same target, the target must succeed on a DC 14 Wisdom saving throw or become frightened for 1 minute. While frightened this way, the creature believes it has shrunk to half its normal size. All attacks against the creature do an extra 7 (2d6) psychic damage, and the creature’s attacks do half damage. A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage plus 10 (3d6) poison damage, and the creature must make a DC 14 Constitution saving throw. On a failure, the target can’t take reactions and must roll a d10 at the start of each of its turns to determine its behavior for that turn for 1 minute. This works like the confusion spell. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to this effect for the next 24 hours.
