Gem Types

- And many more modifications to discover

Obtaining Spell Gems
Spell gems can drop from any creature in the tower. Use the !togglegems command to disable or enable spell gem drops.
Using Spell Gems
Gems you find go straight into your gem pouch, not your backpack. Open the gem window with Alt+G: your spells and their sockets are on the left, your gems on the right, where you can search, filter and sort them - pick a spell in the filter to see only the gems it accepts. Click a gem and every socket that can take it lights up green - click one to socket the gem there. Right-click a socketed gem to unequip it; it goes back to the pouch.
To trade or sell a gem, right-click it and withdraw it to your backpack. Using a gem from your backpack puts it back in the pouch.
