Here's my story young one. After i've spended more than 2 hours in the character make up screen i've decided that i should go as a female Breton Mage because uh you know my opinion females suit more for this role than beeing a barbaric Xena, anyway after i've travelled through the escape tunnel i've decided to go fully destruction mode but i've also found out that restoration got some nice perks which actualy adds faster mana restore so i've went restoration and destruction. I've actualy wanted to put heavy armor but i've said "no" because it wouldn't roll for a female. As i've grown up in levels i've started to use sneak and went to the guild mage in Winter Hold and i've became after a small short pre-quests a Ladie Arch ***** Mage. At this i've already slained 4 dragons and 1 bone dragon so i've decided to go lulz around and one shot macro everyone with my double fireballs but i've happend to see in my inventory to have a two handed weapon for some nice kill cams.
Hope you enjoyed my lulz story.
My opinion... never go on all specs focus only on one. Warrior Mage Thief and know what you will be doing in the future.
