Best bow to slay Demons?

[Diskordant]

I get to make my own bow for a campaign that will feature heavily in the Abyss. So I'm thinking the best bow for this would be a +5 bane(evil outsider) bane(chaotic outsider) bane(demon outsider) holy bow. This would give me +11 to hit, overcome cold iron, and provide +11 + 8d6 damage. Thoughts? Should I just make +1 seeking speed baneX3 holy longbow and use cold iron arrows?

I'm fairly certain that's not how it would work. Good try though.

Your bonuses to hit and damage from the 3 banes will not stack. The extra 6d6 from the bane will though.

How much are you in need of the to-hit bonus?
Downgrading the +5 to +3 and tacking on 'axiomatic' would do an additional 2d6 damage vs. chaos... while the +3 still suffices to overcome cold iron.

Chaotic and evil I can understand, where does the demon come from?
Speed is better achieved with boots.

If you look at demons in the beastiary they are Outsider(Chaotic, Demon, Evil, Extraplanar). You can choose any outsider subtype for bane. The only reason I wouldn't choose extraplanar is I intend on fighting them in the Abyss, and they lose the extraplanar subtype on thier home plane.

Don't waste money on a +5 bonus - probably better to throw in Holy and/or Axiomatic for extra damage.

And just use cold iron arrows to pierce their DR - they cost, like, nothing at all. And DR/Good is taken care of by Holy.

Sounds like a better set up is +3 holy, axiomatic, bane x3* bow. For +5 to hit and +5 +10d6 damage.

*assuming bane(outsider(evil)) is counted as a seperate weapon enhancement from bane(outsider(chaotic))

Otherwise I'll probably just go with +3 holy, axiomatic, bane(outsider(evil)) and use +1 bane(outsider(chaotic)) arrows for a +5 to hit, and +5 +8d6 damage.
