I know that if two archetypes change the same feature you can't take both but does adding options to a feature (such as bonus feats) count as changing it?
blackbloodtroll is right on this one. That said, if it is pretty obviously not a clashing change in any way (like both adding to the possible selections for bonus feats, with neither removing) then most DMs would be willing to let it slide.
Thanks guys that what I thought but wanted to check that being said as the GM I'm probably going to allow it since the only overlap is in the fact that both archeypes simply give him more options on his feat list.
