The Feat has a one action marker on it, but the description doesn't say anything about a duration. Does that mean that you have to wait until you're likely to be (or have been) exposed to poison, then spend a third of each round maintaining the resistance?
My group's soon to start a new gestalt game, and I want to make a kick-arse magic-slinging archer. I'm sold on the zen archer qinggong monk, but I'm not sure what to pair it with. I'm torn between an eldritch archer magus and an empyreal sorcerer that PrC's into arcane archer.
