Except for the fact that I'm not missing very much at all. It only takes 2 my two BAB (which, if I counted correctly, only increases it to 8 to-hit instead of 6) and yet gives me +4 damage.

My character sheet. Influences that I've counted...
+3 due to strength
+1 due to song
+1 due to Weapon Focus
+1 due to Ember Great Axe (which I'm not wielding in my character sheet, but I will go back to wielding when it's time for adventuring)
