Sense Magic. The skitterer senses magic within 120 feet of it at will. This trait otherwise works like the detect magic spell but isn't itself magical.

Sunlight Sensitivity. While exposed to sunlight the skitterer’s AC drops to 17 and the multiattack is reduced by 1 attack.

Multiattack. The skitterer makes two claw attacks and one tentacle attack.

Claw. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 15 (2d6 + 7) slashing damage and 11 (2d6+7) necrotic damage.

Tentacles. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 22 (3d8+7) poison damage. The skitterer heals for the same amount of hit points. Creatures hit with a tentacle attack must succeed on a DC 18 Constitution saving throw or be poisoned for 1 minute. Until this poison ends, the target is blinded. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A creature that makes a successful save is immune to this effect for 24 hours.

Ichor Spray: As a reaction, the skitterer can release a spray of ichor, covering all hostile creatures within a 15 ft radius. Affected creatures must succeed on a DC 18 Dexterity saving throw or take 8 (2d6) poison damage and have disadvantage on all attacks until the start of their next turn. No effect on a successful save.
