Kami Eidolon subtype (Wilderness Origins) is sad. Their unique thing only comes online at level 12 (when magic and magic items can hide it pretty well already) and only lasts an hour. If it got it earlier and it lasted any decent duration of time it would have been interesting for a Summoner that wants to quickly bring out their giant friend in a combat situation, but as is the subtype is pure garbage.
The Prophets of Kalistrade vanity in PFSFG lets you reroll day job checks for the cost of a PP. The best that can result in, assuming you turned a 1 into a 20, is 75 GP. 1PP is worth 375GP. There's actually a boon that boosts this vanity (I won't name the scenario, but considering only one is set in the country the religion is based in...) and it still not worth the prestige point.
Speaking of Day Jobs: Improved Day Job feat gives a +3 to day job checks. It's explicitly meant to stack on top of Skill Focus so being strictly worse than that feat isn't that much of an issue. What is an issue is that at the absolute best case (which isn't actually possible) it lets you make a DC40 day job check, getting an extra 50 GP each check. If you took the slow path, and somehow needed it to turn a 37 into a 40 at every single level (which is obviously impossible), that's only 3600 GP over 12 levels. There's some boons that uncap day job or, more importantly, give really good rewards for hitting DC40 (like regain 1 spent prestige), which make it OK, but without outside knowledge it's useless.
edit: Underground Business from Pathfinder Society Primer costs 5PP to add +1 to day job check, and because that's so useful it makes natural 1s give you 0GP, regardless of result. There's vanities that explicitly do nothing mechanically (Herald), but this one doesn't even have RP value since you can have Profession (Pimp) without it.
