A lot of interesting advice. I guess, one thing I was wondering is outside of just doing damage, is there anything I can focus on that would help the party, especially considering my DM's giving me Dual Wielding for free, which does mean I'm free on feats.

Also, despite the power it contains, I'm not quite ready to sell my characters soul immediately. (although, as the campaign goes forward, what happens between humans and otherworldly beings is between them).
