Actualy the best strategy in the fade when confronting the mages is wait, they all start attacking eachother and they will kill eachother untill 1 remains lol.

Also Don't try to make anyone multi-talented, otherwise it fucks them up, going full into one thing is the best to do other than being a mage, which if you know what like 80% of the spells in entropic and spiritual are used in combo's
