Let's talk STORY FEATS. Or, at least, the good ones.
Artifact Hunter is a
crazy boost to Use Magic Device. Take 15 on UMD checks a few times per day? Nice.
Blessed is a feat you can just plain take if you are, say, playing an Aasimar. The basic benefits is
terrible, but the completion benefit is
amazing. A permanent
Protection from Evil effect is basically the bargain-bin equivalent of permanent
Mindblank.
Hey, if you live in a city for at least a year, you too can take
Dynasty Founder! If you have both it and leadership, you have a +3 to your Leadership score. Even if you
don't have Leadership, you attract Followers as if you do. The completion benefit is
OK, but the basic benefit is where the real meat is.
Eldritch Researcher is
amazing if your DM allows you to use the spell research rules. +1 CL with spells you've created yourself would be an OK feat on its own, but the completion benefit tacks on a +1 to the save DC
and one level worth of Metamagic mitigation on top of it. The only restriction is that the spells you make have to be
novel, but that shouldn't be too hard.
Glimpse Beyond is notable because of how
easy it is to get the benefits at higher levels with the right background. Summon an evil outsider, have it kill you, and then have the party Cleric raise you to halve all ability damage you might take to mental ability scores, drive anyone attempting to read your mind insane, and roll twice and take the better on all saves vs. Mind-Affecting abilities. And all for the low, low cost of -2 to Will saves and a feat slot.
Nemesis can be pretty nice - I'm kinda curious if it can combine with that Fast Learner...
Actually, it looks like it should - Nemesis gives you two picks, while Fast Learner alters what your picks get you. I can see a potential for +2 HP and +2 skill points per level. Assuming, of course, that your DM allows you to chain Fast Learner off of Nemesis (Nemesis requires that one of your picks be +1 HP or +1 skill points; Fast Learner says you get both instead of picking one of them).
EDIT: A Human with the
Finding Your Kin trait, the Nemesis feat, and Fast Learner receives +2 HP and +2 skill points whenever they take a level in a Favored Class
on top of whatever they picked as their Favored Class benefit. You can do this
at first level if you have an appropriate backstory.
I'm hard pressed to think of a case where two copies of Toughness
plus two copies of the Skilled racial trait
plus the potential to get a +2 to an ability score later on down the line isn't a good use of two feats and a trait.
