Traits

Long-Legged Strider. Difficult terrain composed of rocks, reefs, or rubble doesn’t cost the aitu extra movement.

Rhythmic Clack. Creatures within 300 feet can hear the aitu’s stilt-legs striking stone (no action required). A creature that succeeds on a DC 14 Wisdom (Perception) check pinpoints its direction but not its exact location.

Top-Heavy. Whenever the aitu is knocked prone, its speed is reduced to 0 until the end of its next turn, and attack rolls against it have advantage until it stands.

Sure-Footed. The aitu has advantage on Strength and Dexterity saving throws made to resist being shoved or moved against its will.

Actions

Multiattack. The aitu makes two Stilt Kick attacks. If both kicks hit the same Medium or smaller creature, the aitu can make one Claw attack against that creature as a bonus action.

Stilt Kick. Melee Weapon Attack: +6 to hit, reach 15 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage, and the target must succeed on a DC 14 Strength saving throw or be pushed up to 10 feet.

Claw. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 8 (1d8 + 4) slashing damage, and the target is grappled (escape DC 14) if the aitu isn’t already grappling a creature. Until this grapple ends, the target is restrained, and the aitu can’t use that claw on another target.

Bonus Actions

Leaping Stride (Recharge 4–6). The aitu jumps up to 30 feet to an unoccupied space it can see. This movement ignores opportunity attacks and may include vertical distance.

Reactions

Balancing Hop. When the aitu would fall prone, it can make a DC 14 Dexterity saving throw. On a success, it remains standing.

Lore

A cannibal with extremely long, stilt-like legs; he strides over reefs, ravines, and cliffs so fast that his prey can hardly escape.

Aitu-i-vaē-toko (literally, “Demon on Stilt-Legs”) belongs to the kai tangata cultural archetype (kai tangata — man-eater, devourer of humans), a theme deeply woven into the history of the Marquesas Islands. The monster’s distinction lies in its flawless adaptation to broken terrain filled with reefs, ravines, and cliffs: its legs are unnaturally long and thin, like wooden stilts. These disproportionate limbs give it a fearsome height and let it move with alarming speed across hostile landscapes.

Aitu-i-vaē-toko is a massive, revolting, humanoid creature with an insatiable appetite for human flesh. Its towering stature alone commands dread. One unique trait must be mentioned—the rhythmic clack of its stilt-legs (toko-toko) against stone and reef is a chilling signal that a deadly chase has begun.
