For some reason I feel like dismembering/decapitating orcs or somesuch with... an arrow.
Mechanics wise... I think this'll be it;
Paladin of Freedom 3/Barbarian 3
Str 16, Dex 16(+2 Racial), Con 10(-2 Racial), Int 10, Wis 10, Cha 14
1st: Ranged Smite Evil (BoED): You can use a smite evil attempt through a ranged weapon.
3rd: Point Blank Shot
Composite +3 Longbow (700 gp)
Composite +5 Longbow (900 gp) (*Probably just a higher-tension string fluff-wise, she'll restring the longbow during combat as a move-action instead of drawing it seperately)
50 Arrows (300 gp)
10 Adamantine Arrows (900 gp)
What do you think of a homebrew feat or feats allowing her to trade a second or third full-attack for a more powerful one? For instance...
Requirements: Point Blank Shot? Bab +6
Benefit: As a full-round action, you can trade an additional attack granted by your BaB to increase the damage done by your remaining attacks. Your remaining attack(s) suffer a -5 penalty to attack but the damage is doubled.
Requirements: BaB +11
Benefit: Foregoing two additional attacks increases the penalty to -10 and triples the damage.
Requirements: BaB +16
Foregoing three attacks increases the penalty to -15 and quadruples the damage.
If you want to know what inspired this... go about 13 minutes into Princess Mononoke.
So, being level 6... and assuming she was raging, my character could forego an additional attack with her composite +5 longbow and deal a solid 1d8+5 damage multiplied by 2. That's anywhere between 12 to 26 damage per hit... and if she gets a critical, something between 24 to 52.
Fair warning, she could get up into the hundreds of damage with some proper gaming of the Greater Version or even Superior Version... perhaps they ought to be scrapped.
