Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Melee Claw +6 (agile, finesse, unarmed), Damage 1d4+2 slashing

Ranged Shortbow +6 (deadly d10, reload 0, range increment 60 feet), Damage 1d6 piercing

Explosive Death

When the skeleton is destroyed, its bones shatter and explode as the necromantic energy holding it together is released. Adjacent creatures take 1d6 slashing damage with a DC 15 basic Reflex save.
