We're starting a new game in a couple weeks and I'm planning to roll a Dwarf Alchemist. As I am currently running a PF2 game, I've seen now nasty poison can be against players and a combination caught my attention: Hardy (ancestry) and Poison Resistance (Alc4). I can't seem to find mention anywhere of resistance of the same type stacking or not stacking. Have I overlooked something or has this been addressed elsewhere?
