Lead Cloud (poison)

Trigger The leaded skeleton is hit by a melee attack

Effect A cloud of lead dust is released, forming a 5-foot radius cloud of fine particles surrounding the skeleton. The cloud persists for 1 round, exposing creatures within it to an inhaled form of rapid lead poison.

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.

Speed 15 feet

Melee Leaded Bone-fused Hammer +13 (shove), Damage 2d6+6 bludgeoning plus Rapid Lead Poison

Melee Leaded Claw +13 (agile), Damage 2d6+4 slashing plus Rapid Lead Poison

Rapid Lead Poison (poison)

High amounts of lead can cause headache, difficulty concentrating, and joint pain. Necromantic magic has augmented the lead that infuses this skeleton, causing it to take effect far more quickly than is typical for lead poisoning.

Stage 2 2d6 poison damage, stupefied 1, and Clumsy 1 (1 round)
