To enchant gear you need to have the spell Enchant Weapon or Enchant Armor which will take the base enchant value and attempt to increase it by 1. You can also use scrolls of the desired spells. Using scrolls does not require a gem reagent but always have the effect of some amount of spirit and earth skill, meaning it won't work beyond +1 or +2.
Enchanting has a chance of destroying the item and hurting yourself. For maximum efficiency on enchanting you will need many skill points trained in Spirit and Earth magic. For instance to enchant an item from +2 to +3 with 13 Earth and 7 Spirit gives a 60% chance, and to enchant an item from +6 to +7 with 36 Earth and 35 Spirit suggests a chance of 31 percent.
Cost of Enchanting
The enchanting spells require a diamond for weapons and a ruby for armor. The gems must have a certain value for the spell to be cast, but otherwise the value of the gem does not affect the success chance. If you have the spell you can find out the cost by casting and choosing an item.
Enchant tokens are scrolls found in wherever scrolls are sold for 10 gold. They allow anyone in the Mages Guild to use the "prepare" command to cast the enchant spell for any enchant stat up to 7 and apply that stat and success chance to the token to be used at a later time or to be sold once. The token will show the chance of success based on the caster's skills.
