- Main article: Soul Gem (Oblivion)
Soul Gems are used for harvesting the souls of unsentient creatures and then binding them into the gem. This bound soul can then be used for enchanting weapons and armor, or other purposes of the arcane.
The Lesser Soul Gem is the second smallest size Soul Gem, and can only carry white souls equal or lesser than the "lesser" category. When filled with the best applicable soul, their capacity utilized in enchanting is 300.
