Using URM once again, look up worldChars, go into the list, find yourself, or another character you want to adjust (only touch the ones that can be members of your party, for caution's sake), then into .props
That gives you a list of every single property of a selected character, including unspent attribute points, and skill points. Perks are located there too, but those have to be added manually, and cross-referenced to figure out the correct names for them.
Lmao, you don't even need python knowledge.
As a rule, if you want to tinker with Ren'Py games variables yourself, you need exactly 3 things. Universal Ren'Py Mod, grviewer.com to unpack .rpa files and read them, and patience.
All it took me to figure this one out.
