Gotta say, I'm a fan of the write. I like the re-contextualization and actual intrigue this gives ologs.
My only criticism comes in the form of the Rage ability, and the sudden brain-blast ologs would get- though i absolutely love the "get a kill to extend your Rage" trait.
Making Ologs 'dumber' mechanically as opposed to thematically may be the way to go. I'm sorry, I don't see an olog actually bothering to use alchemy/golemancy, let alone the further alchemy(s) such as tawkin or animatii. MAYBE smoggers gets a pass?
I think making them take twice as long to learn knowledge-based FAs would be best, with further alchemy(s) being wholly inaccessible- or/and making them incapable of making CAs based off of those feats with the exception of sorvians as making little clay sculptures supported by wood and blood is absolutely something someone with massive hands could enjoy.
Edit: Just an afterthought for the magics. maybe a limit for what tiers of magic an olog can use, similar to scionism, could be applied instead of sacrificing the olog's rage if they decide to pick one up. not because they are actually stupid, but because their minds are too volatile/filled with internal turmoil to reach those upper-limits of what a descendant's mind could do? again, 'mechanically' stupider, not literally.
Suggestions for Rage are within the Spoiler, along with the quoted ability itself for ease of access.
all and all, +1 my dude. hope this goes somewhere.
