Multiattack

The spider thief makes one Hooked Wire attack and one Sickle Claw attack, or it makes two Sickle Claw attacks.

Sickle Claw

Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 10 (2d8 + 1) slashing damage.

Hooked Wire

Melee or Ranged Weapon Attack: +3 to hit, reach 5 ft. or range 15/30 ft., one target. Hit: 6 (2d4 + 1) piercing damage, and the spider thief pulls itself in a straight line up to 25 feet toward the target, stopping in the nearest unoccupied space to the target. When the spider thief moves in this way, opportunity attacks against it have disadvantage.
