Souls with a superscript (e.g., L:-1) are leveled see the later section for details. See individual creature pages for full details on their souls. Unique creatures (like the lich Lorgren Benirus) generally have leveled souls that are not in this table. This table provides soul strengths for most of the standard creatures in Oblivion. Trapped souls are used to enchant and recharge items. Souls are trapped in soul gems by using a soul trap spell. More powerful creatures have more powerful souls.
Every soul in Oblivion is one of six possible strengths: Petty, Lesser, Common, Greater, Grand, and Black.
