I'm starting to love my soon-to-be Arcane Archer. There's something about being able to kill skeletons with a bow on elite (which, normally, is all but impossible because of DR) that's just intensely pleasing.
I've fallen in love with my Elven Wizard that I just made. A much different feel from my level 6 Half-Elven Sorcerer, and I think it's actually a better feel.
I'm definitely going Pale Master, simply because that self-healing is extremely delicious (not to mention the death aura is very nice to have) and because insta-kill spells will also be delicious when I get them.
However, there is one single spell I've fallen in love with. Sound Blast.
Destroying breakables, stunning groups of enemies while dealing fairly significant sonic damage to them, oh, and it only costs 4 SP. Love it so much.
Disrupt Undead is underwhelming damage considering that it only targets undead. I think it could've stood to either have additional effects, or quicker-scaling damage.
