The closest thing I can think of is a Magus with the Soulforger Archetype 2e.aonprd.com/Archetypes.a...

That shit drives me insane, its the most unoriginal slop

Its a one-off entry in a setting book that is conveniently between where the party is and where they need to go :P. pathfinderwiki.com/wiki/Witchli...

The lore is so funny, 7 thousand years ago a local tribe was exploring a crashed alien ship (happens a lot in the setting) and accidentally set off a nuke, oops.

Oooooo

We aren't anywhere close to snow on the we(s)t coast lol

Monk with guardian archetype seems like a first step, get that legendary unarmoured.

Love that they have a good handle on their scope. No stretch goal scope creep here :D

Yuuuuup
