I've got a PFS character who has, from Invulnerable Rager, the benefits of Resist Elements versus hot. He's also got, as a scenario arc boon, the benefits of Resist Elements versus cold.
He's also got the Endurance > Die Hard > Fast Healer feat chain and an 18 CON.
So, aside from mocking all the other characters about how, back in his day, you had to WALK to your encounters. Through 19 feet of snow. Uphill. Both ways. To wrestle a fire elemental. And we were GRATEFUL...
Are there any synergies here to exploit? Or does the Endure Elements effect largely prevent the circumstances where most of the benefits of Endurance vis a vis climate matter?
Not that the roleplay potential isn't worth it. :)
By "Resist Elements" do you mean endure elements or resist energy? Either way, I don't see much of any synergy to exploit. Endure Elements covers the entire nonlethal damage range, so you never get to make the check Endurance gives you a bonus on. I seem to remember some technicality that made freezing/overheating damage not the same as cold/fire damage, but most people seem to forget or ignore that (or perhaps it was fixed). Either way, doesn't really interface with Endurance.
In terms of roleplaying, I would choose to be a total jerk about the weather. Wear a cold-weather outfit and furs in the desert, then switch to a hot-weather outfit in the snowy north. Constantly complain about how 100 degrees is too cold and 0 degrees is much too hot. Pretend to shiver while everyone else is making checks to keep off heat exhaustion and fan yourself when they are freezing to death. If you are lucky they will laugh with you, and not chop you up tauntaun-style.
Sorry, I meant Endure Elements.
And that's kind of what I thought. It completely prevents me from having to make the Fort save at +4 for Endurance.
The character is a cranky old coot who came out of retirement. Indeed, sort of like a former California governor taking up an iconic role... :)
