Is it because of the low base dmg of a phase blade that you do not invest points into sword mastery?

Also I agree with the guy that says use a phoenix shield. You have zero defence anyways - faster you can kill the better. If in doubt use leap (Knockback) and howl (to make them runaway) together.

And when I used Berserk - it can still be a good one point wonder. You can do ww as main attack.
