Instead of using a real mage, choose any of the creatures in Academy whose combined spellbook points add up to 4 to be your "mage". You can have any training you want.
You have no channeling stat. You have 60 starting mana . Spellbook size is still 40 points. There are no setup rounds. You can only cast up to two spells per round, and you do have a quickcast action. An equipment can only target and be attached to one "mage" creature at a time. If you have the same training as a real mage, than you have access to their mage-class only equipment spells.
Other than that, the rules are the same as normal. Enjoy!
