A fiercely sculptured reptilian head curves sinuously into a rigid glaes body. A mixture of ophidian grace and rock hard volcanic glass with the impassive frigidity of both, the soul golem radiates power and malice. Standing about eight feet tall and four feet wide at the shoulder, its massive frame dominates the area. Within the chest of the golem, a pure white mist is frozen solid in the glass, pulsing with a sickly glow. As a contrast to the frozen horror of its chest, its soulstone eyes flare with a brilliant viridian light.
These creatures appear to be immune to all forms of normal damage from sorcery, health-damaging spells (like Harm and Pain), all elemental sources of damage, and all curses. Furthermore, they are puncture-resistant and cannot be kneecapped with Cheap Shots. Holy spells and holy effects (such as holy water flares, Voln-based holy damage abilities, and various cleric secondary effects) still damage them.
Soul golems have the ability to remove Lifekeep from a corpse:
A soul golem extends its glaes hand into your chest. After a brief pause, the chest piece of the golem glows slightly brighter. Your senses tingle slightly, and you almost think you hear a faint, sinister laugh.
You feel the preservation on your spirit fade.
