Possible Soul Gem distribution issue
When in a group the soul gems you create by using this spell can be picked up by any member of the party. This should be considered before using this relatively expensive spell.

=Soul Gems reported= Soul Gems may be used in the Stone of Change (Adamantine Rituals use Soul Gem: Essence of Earth), trapmaking (until Update 11]), and [[Cannith Crafting; see Crafting Soul Gems for a list. Soul Gems can be stored in Small or Medium Soul Bags.
