@ Bapitty exactly i feel the worst thing for an unarmoured mage is to be surrounded but still i cant decide never really played a mage in oblivion so im not that skilled in it application but would really like to try it in skyrim
It's not that hard. Usually, I just use my crowd control spell on the closest enemy (or enemies), then follow it up with debuffs and destruction spells. Btw, from the footage I've seen, mages die FAST in Skyrim. Although if you're careful with your alteration spells and have a weapon, you can do without excessive crowd control.
I just love Illusion too much on pure mages to give it up, though. Even from a roleplaying perspective, a master wizard wouldn't dirty his hands on common enemies. He'd make them kill each other!
