my pure mage: alteration, strangely my destruction is the lowest mage skill(68) and even conjuration beats that(70) and i rely on my dual firebolt when battle.....i guess i summoned too many things. And no, i dont count Illusion as 'magic' despite it says magic.
my archer: marksman, duh
my 2 handed sword warrior: Archery..........=.= i guess i rely on bows more since they are more OP and i die lesser
and my non-violent-no-killing-allowed character: smithing

iron daggers ftw
