Pack Tactics. The kobold warrior skeleton has advantage on an attack roll against a creature if at least one of the kobold warrior skeleton's allies is within 5 feet of the creature and the ally isn't incapacitated.

Multiattack. The Kobold Warrior Skeleton makes two attacks: one with each of its two claws.

Claws. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage.

Spear. Melee or Ranged Weapon Attack: +4 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 5 (1d6 + 2) piercing damage, or 6 (1d8 + 2) piercing damage if used with two hands to make a melee attack.

Lesser Necklace of Fireballs bead (1). The Kobold Warrior Skeleton hurls a single bead from a Lesser Necklace of Fireballs (it possesses a single bead, not an entire necklace) up to 60 feet away. When it reaches the end of its trajectory, the bead detonates similar to, but with less force than a 3rd-level Fireball spell (save DC 14). Each creature in a 20-foot radius sphere centered on that point must make a Dexterity saving throw. A target takes 5d6 fire damage on a failed save, or half as much damage on a successful one.
