Usage:
enchant <object> levitation
enchant <object> concealment
enchant <object> thermography

These mage enchants are relatively obscure.

The levitation enchant causes the target object to float.
The concealment enchant causes objects to become permanently invisible.
The thermography enchant is used on head pieces to grant permanent
infravision spell when the item is worn.

These enchantments are permanent and irreversible, but they have a
relatively low gold cost. Thermography also requires a spell component
with an affinity for the infravision spell or alteration magic.
