Shurale

The shurale’s spellcasting ability is Charisma (spell save DC 15). It can innately cast the following spells, requiring no material components.
At will: dancing lights, invisibility (self only), minor illusion
3/day each: detect thoughts, major image, misty step
1/day: confusion

The shurale has advantage on saving throws against spells and other magical effects.

The shurale’s weapon attacks are magical.

The shurale regains 5 hp at the start of its turn for each creature within 30 feet of it that is incapacitated with laughter from its Tickle action. If a creature dies while suffering from the laughter, the shurale gains 15 temporary hp.

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

The shurale can use Tickle. It then makes three attacks: one with its gore and two with its battleaxe.

The shurale touches a creature within 5 feet of it. The target must succeed on a DC 15 Wisdom saving or begin to laugh uncontrollably for 1 minute. While laughing, the target falls prone, is incapacitated, and unable to move. 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 the shurale's Tickle for the next 24 hours. If the target fails the saving throw three times, it must succeed on a DC 15 Constitution saving throw or be reduced to 0 hp and begin dying. On a success, the laughter ends on the target, as normal.
