The Wizards Guild (located in Valmorgen and Lormidia) can enchant the weaponry and armour of heroes, sells various magical items and can learn non-spellcasters the ability to cast spells, which can then be bought from the Library in Valmorgen.
Heroes that do not have the ability to cast spells can learn it at the Wizards Guild. An Intelligence of 11 or higher is required to learn spellcasting. A hero can train intelligence at the Library in Valmorgen.
Both Wizards Guilds allow heroes to enchant their weapons and armor to +3 from the start of the game. Enchanted weapons do more damage and enchanted armor gives extra protection - not just an increase in armor, but also an extra protection against critical hits. The bonus of an item is shown as a +x behind the armor/damage stat (they are not added in the yellow number like other bonuses to these statistics). The Lormidia Wizard Guilds allows a Hero to upgrade their weapons and armors to +4 after completing the Ascend the Wizard's Tower Quest.
From unenchanted to +1: 200 gold
From +1 to +2: 400 gold
From +2 to +3: 800 gold
From +3 to +4: 1600 gold
