I've (finally) started looking at archetypes; specifically the ones in Ultimate Magic. And I noticed something that I'm not sure how to interpret. In the very first archetype I found.
The chirurgeon archetype for the alchemist loses the poison resistance +4 ability, but not the poison resistance +6 ability. When a chirurgeon hits 8th level, would he have a +2 bonus, a +4 bonus, or a +6 bonus?
My assumption is that he would have a +4 bonus, but I don't know for sure.
It indicates that you would gain the next ability in the process instead of the higher one... so you would get the +2 bonus as normal, then when it would normally get the +6 you instead get the next in the sequence (+4).
