Another one I love is MNmaxed. Great characters and the players are all fun people. Primarily Pathfinder 2e content.
It looks like the Exemplar is actually a new martial.
It sounds like you handled it fine. This feels like it sort of falls in between Coerce (Using the threat of the mitflit's boss. Your boss sent us, so you need to do X, or else the boss will be mad.) and the player attempting to Make an Impression. Generally speaking each of those take a minute to accomplish, so are hard to do in combat. So it would very much be a GM decision. Another option would to have the Mitflit flee for a round or even attempt to run back to the boss to check (which could bring reinforcements). But with all that said, you rewarded the player's idea and critical success, even if it isn't exactly what the player was hoping for. So, well done!
Pathbuilder2e easily the best character builder out there. Also for GMs, they have a great encounter builder/combat tracker even with it being in beta. https://pathbuilder2e.com/beta/encounters.html
Ooh, this is a really cool concept! I especially love the planes mapping to deadly sins and how they can have massive interactions.
I love the animal instinct barbarian/wrestler combo. How did you build the character out?
I am running a campaign based in and around (and under) a dwarven metropolis that explores the nature of power, corruption, and what it truly takes to be a God. The players fight to dismantle a mafia that is secretly controlling the city, uncover a demonic cult hell bent resurrecting a dead God, and realize the true cost of power.
