Special arrows for Hawkeye

[Neils Bohr]

I'm trying to get some utility arrows for our ranger to trick him out like Hawkeye or the green arrow.

I've seen the smoke arrows and blunt arrows in ultimate equipment, but I'm looking for some more.

I'd prefer to stick with paizo material, but I might be able to use third party if there is something good.

At higher levels the trapper ranger can attach his traps to his arrows.

There's a page in the Alchemy Manuel.
