Best Stacking Feats?

[pabelfly]

I was looking at "Abyssal Heritor" feats, and I see that they power up based on how many other "Abyssal Heritor" feats you have.

For example, "Demonic Skin", without any other feat, gives you +1 AC, but if you get a second feat, say, "Eyes of the Abyss", "Demonic Skin" grants +2 AC instead, and "Eyes of the Abyss" gains 30ft Darkvision, as well as +2 to Spot and Search, due to having two "Abyssal Heritor" feats.

So my question is - are there any other good feat lines in a similar vein, that give extra bonuses for having multiple feats of the same type?

One that might be of interest to the Knowledge Devotion types who don't have access to the Knowledge domain is Draconic Knowledge (Dragon Magic) - as distinct from the feat of the same name which is a monster feat and comes from Draconomicon. All Knowledge skills become class skills for all your classes, and you get an untyped bonus to Knowledge checks equal to the number of draconic feats you have. Draconic Knowledge itself is draconic, and Draconic Heritage is its prerequisite, so that's a minimum of +2 to all knowledge checks, which are all class skills. I can't think of many situations where it'd be that handy as such since most of the other draconic feats just don't seem that scaleable and offer tiny bonuses, but maybe if you really wanted to wring every point out of your Knowledge checks because you're doing a lot of ability damage and your DM reads K.Devotion's bonuses as apply to ability damage, not just hitpoint damage ... say, you've got some sort of poison-focused rogue with lots of skill points available and have a touch of sorcerer as well or something ...

I know they're really weak, but I've always felt the Combat Focus feats are suuuuuuuuper weak in 3.5 but would have made a good theme for a 5e archetype. PF1E also did a good set of stacking feats, Outslug Style being my favorite, partially for the 10-foot step, partially because they stack.

Aside from the Abyssal Heritor feat chain, I'm not sure there's more than a couple feat chains that stack in the same way.

Well I have wanted to build a blaster sorcerer with Knowledge Devotion so this is a pretty neat recommendation. Thanks.

I have a secret love of the Combat Focus feats, Combat Defense helped me win a build comp (Truespeak Warrior in my sig if anyone cares).

I recall a thread that suggested Roll With It was a good feat if you had unlimited of one feat because each time you take it it adds to your DR/- by… 2 I think it was. Eventually you just have ridiculously high DR/-.

That's not bad, but I'm looking for synergistic feat groups like Combat Focus feats and Abyssal Heritor feats, where taking feats in the same group boosts each feat's individual power.
