Attick

Never Sleeps. The Attick does not sleep and cannot be put to sleep by magic.

Star-Lit Hunter. Two magical stars follow the Attick, hovering above it. The stars shed bright light in a 10-foot radius and dim light for another 10 feet. The Attick can dim or brighten this light as a bonus action, but the stars cannot be fully extinguished while the Attick is alive.

Hard to Kill. If damage reduces the Attick to 0 hit points, it must make a Constitution saving throw with a DC equal to 5 + the damage taken, unless the damage was dealt by a silvered weapon or a spell. On a success, the Attick drops to 1 hit point instead.

Silver Weakness. A silvered weapon ignores the Attick’s resistance to nonmagical weapon damage. If the Attick takes damage from a silvered weapon, it cannot use Hard to Kill until the end of its next turn.

Burrow Furnisher. The Attick ignores difficult terrain caused by furniture, clutter, rubble, cramped tunnels, curtains, rugs, and lair debris. While in its lair, it has advantage on Dexterity (Stealth) checks made among stolen furnishings.

Mean Little Monster. The Attick has advantage on attack rolls against a creature that has not damaged it since the end of the Attick’s last turn.

Multiattack

The Attick makes two Guard-Claw attacks and one Venomous Bite attack.

Guard-Claw Melee Weapon Attack: +6 to hit, reach 5 ft., one target.
Hit: 10 (2d6 + 3) bludgeoning damage, and if the target is Medium or smaller, it is grappled. Escape DC 14.

Until the grapple ends, the Attick cannot use its Guard-Claws against another target, and the grappled target has disadvantage on saving throws against the Attick’s Venomous Bite.

Venomous Bite.Melee Weapon Attack: +6 to hit, reach 5 ft., one target.
Hit: 10 (2d6 + 3) piercing damage, and the target must make a DC 15 Constitution saving throw.

On a failed save, the target takes 14 (4d6) poison damage and is poisoned until the end of its next turn. On a successful save, the target takes half as much poison damage and is not poisoned.

Melting Gaze. The Attick targets one creature it can see within 30 feet that can see the Attick’s eyes. The target must make a DC 15 Constitution saving throw.

On a failed save, the target takes 27 (6d8) acid damage, and its speed is reduced by 10 feet until the end of its next turn as its body begins to soften, blister, and melt.

On a successful save, the target takes half as much damage and suffers no speed reduction.

If a creature is poisoned by the Attick’s Venomous Bite, it has disadvantage on this saving throw.

If this damage reduces a creature to 0 hit points, the creature’s body partially liquefies into a melted ruin.

Recharge 5–6.

Star-Flare. The Attick’s following stars flash with cruel yellow light. Each creature of the Attick’s choice within 15 feet that can see the stars must succeed on a DC 15 Constitution saving throw or be blinded until the end of its next turn.

Recharge 6.

Face-Guarding Claws. When the Attick is targeted by a ranged attack from a creature it can see, it raises its red guard-claws defensively, gaining +2 AC against that attack.

Spiteful Skitter. When a creature misses the Attick with a melee attack, the Attick can move up to half its speed without provoking opportunity attacks from that creature.
