This is a compiled list of creatures and their known level ranges. I put this list together to help people know what creature fills what size soul gem. I would like this to become a "Living" thread and open to expansion. If I missed something or if I mislabeled a creature please let me know and I will make the appropriate edits. It took a good bit of research from several sources but it's finally ready to post. Just to clarify the level needed to fill each Gem: Petty: 1-3 Lesser: 4-15 Common:16-27 Greater: 28-37 Grand (Black): 38+ (NPC) Petty Creatures: Alpha Wolf Chicken Cow Deer Dog Draugr Thrall Elk Fox Frostbite Spider Goat Horker Mudcrab Rabbit Skeever Skeleton Slaughterfish Wolf Lesser Creatures: Bear Chaurus Draugr Restless Draugr Wight Falmer Skulker Falmer Flame Atronach Frostbite Spider Giant Frostbite Spider Horse Ice Wolf Ice Wraith Pit Wolf Sabre Cat Snow Fox Snowy Sabre Cat Spriggan Troll Werewolf Wounded Frostbite Spider Common Creatures: Cave Bear Chaurus Reaper Draugr Deathlord (Common, Greater, Grand) Draugr Overlord Draugr Scourge Lord Draugr Scourge Falmer Nightprowler Falmer Shadowmaster Frost Atronach Frost Troll HagravenSnow Bear Spriggan Matron Greater Creatures: Draugr Death Overlord Draugr Deathlord (Common, Greater, Grand) Giant Storm Atronach The Pale Lady Wispmother Grand (Black) Creatures: NOTE: Any NPC captured with a Black Soul Gem counts as a Grand Soul Dragon Priest Draugr Death Overlord Draugr Deathlord (Common, Greater, Grand) King Olaf One-Eye (Doesn't require Black Gem) Mammoth Potema's Remains Hope this helps anyone grinding out enchanting or anyone who doesn't have the Black Star yet.
