Oh wow, checking the stats in the menu... to be honest, I should have known that.
I'm at 299 power and 30 skill, and yet... it didn't seem to work. I think I probably missed out on like 5-10 stats throughout the whole game... and I really don't want to replay it all min-maxing stats with broken immersion using a guide.... hm. Maybe I could try fiddling with the save file because the wiki says I should be able to do both, maybe I'm missing 1 power or skill. I dunno. Or maybe I just need to suck it up and pick one option to proceed with.
