Dead Shot auto-scales and doesn't cost you 3 feats though, which is nice.

I supposed Deadly Aim is good. I'm still worried a bit about missing however Is that +4 damage really worth the -2 to hit if my base damage per shot is alreayd 3d6+8? The math depends on the AC of the enemy of course, but I feel that the bigger your damage already is, the less worth it Dedly Aim.

I wonder how I can jack up my accuracy besides Weapon Focus and increasing Dex. We don't have a Bard in the party.
