Trap the Soul

{{Infobox-spell Although this essentially 'kills' the target, it is not a Death effect and functions on creatures such as Undead but not most Constructs. This spell requires a Khyber Dragonshard as a special material component. It is often helpful to cast Enervation on a target before casting Trap the Soul to reduce the creature's saving throw.

Material Components

 * As of Update 50 requires a standalone special component called a Khyber Dragonshard that is found in shops wherever high quality spell components may be found. Update 54 also removed the Hit Die related variants and the spell only produces the standard gems.

Note that items with the Trap the Soul (item enchantment) don't need the material component.

Soul Gem distribution notice
