Soul Gems are items used for resurrecting and for keeping weapons enchanted in The Elder Scrolls Online
You find soul gems, or buy them from a Mystic such as Saerdor
Mystics are usually found in the Trade District of a town.
Then you can use the soul gems for 2 purposes:
- Revive yourself or another player
- Recharge your enchanted items
Soul Gems have different sizes and you need to use a soul gem of an appropriate size for the item you are recharging or the player you are reviving. For example, a Common Soul Gem is used for level 30-39 players/items, while a Grand Soul Gem is used for lvls 50 and above
If you have an empty soul gem, such as the Grand Soul Gem, you have to capture a soul first using soul trap before the soul gem can be used.
