Form of Madness. Any creature within 60 feet of an ekolid must make a DC 12 Wisdom saving throw. On a failure the creature begins hallucinating that tiny biting insects are infesting its hair, skin, and clothes, becoming frightened for 1d4 rounds. A creature that makes the save is immune to that particular ekolid’s form of madness for 24 hours. Other chaotic evil fiends are unaffected by this special trait. Looking at multiple ekolids requires a separate save for each one’s form of madness, but the effects are not cumulative.

Quickness. The ekolid can dash as a bonus action.

Multiattack. The ekolid makes three attacks with its sting.

Sting. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4+3) piercing damage. On a hit, the target must make a DC 12 Constitution saving throw. Failure indicates that the ekolid implants an egg under the creature’s skin. The egg hatches at the start of the ekolid’s next turn, at which point a ravenous ekolid grub gnaws its way out of the victim. This deals 4 (1d6) points of necrotic damage per egg that hatches and the victim is poisoned for 1 round (no matter how many eggs hatch). As an action, the victim can remove the egg before it hatches. Newly hatched ekolids are otherwise harmless, but grow to maturity quickly over the course of only a few hours. A hatched grub falls to the ground after crawling free of its host. A grub has 1 hit point and effectively no Armor Class.
