there's a chair in the inn you can use to influence your pawn's inclination
scather is good for meleers you want to engage bosses (especially fighters, who will essentially tank), medicant sucks don't use it, mitigators is good for rangers and sorcerers if you want them to use aoe, challenger is good if you want a pawn to take out ranged enemies (really good for a sniper), guardians are bad because they'll just stay near you and not proactively engage enemies, nexus is alright on spellcasters if you want them to prioritize buffs, pioneer and acquisitor are usually unwanted but together they can make a memey gathering pawn that actively scouts ahead during battle grabbing everything they see
utilitarian is different in that it can either be absolutely useless or gamechanging. a utilitarian pawn is only as good as its battle knowledge. you might have seen pawns actively going after certain enemy weaknesses, such as using fire on enemies that fear it, fighters springboarding you in the air with their shield so you can grapple on an enemy's weak point easier, etc. all pawns will take advantage of these weaknesses to some degree as they see them (throwing fire on an enemy weak against fire has a chance to "teach" that tactic to the pawn, filling in its entry in the bestiary), but utilitarians will ruthlessly exploit those weaknesses. in addition, they will call out weaknesses they know to the party, and other utilitarian pawns in the party (even if they don't know that weakness!) will follow those orders. one example i've seen is a pawn with knowledge calling out "it's weak to fire!" and another utilitarian pawn immediately begins casting fire boon. also, if you have multiple utilitarian sorcerer pawns, they'll chain cast superpowerful spells together. it's legitimately awesome to watch.
utilitarian kinda fooled people for years into thinking the AI literally is capable of learning, but naw, each enemy just has a couple of hardcoded weaknesses to discover. the AI DOES seem to keep a record of how often you use certain abilities if you're the same class as them and it affects their skill usage, but it doesn't seem to massively impact combat
by the way, up to three inclinations can be in effect at once. top two are shown, the third is hidden
She has guardian primary and scather secondary, not sure about the hidden one. Heard that rental pawn inclinations can affect your pawn as well, so I'm making sure that both rentals don't have guardian as their primary. She doesn't seem to be a hindrance anyway though, so I'm not too concerned right now. I have the meteor spell as one of her secondary skills, it wreaks havoc when she busts it out. ---
