CREATURE 4

UNIQUE MEDIUM EVIL SKELETON UNDEAD UNHOLY

Rusting Death

When Theiltemar is destroyed, his bones explode as the necromantic energy holding him together is released. This shreds his rusted chain mail as well, flinging rusty shards of jagged metal in all directions. Adjacent creatures take 2d6 piercing damage (DC 21 basic Reflex save) and are exposed to rust creep. As his remains settled to the floor, the wall of force blocking area F14 flickers and fades.

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 25 feet

Melee Claw +12 (agile, finesse, unarmed), Damage 2d6+4 slashing

Divine Spontaneous Spells DC 21, attack +13; 2nd (4 slots) Blood Vendetta, Darkness, Sudden Blight, Harm; 1st (4 slots) Bane, Command, Fear, Harm; Cantrips (2nd) Daze, Divine Lance, Prestidigitation, Read Aura, Shield

Rust Creep (disease, divine)

Those afflicted by rust creep develop uncomfortable rust-colored bruises on their flesh and endure full-body aches like those one might experience after a long workout. As the affliction progresses, their bodies—as well as the clothing and items they wear or carry—increasingly break down until a painful death occurs. If a character successfully resists contracting rust creep, or recovers from a case of rust creep, they are temporarily immune to future rust creep infections for 24 hours.
