So for character creation / adding more points at the start, you'll probably want to modify the existing presets to increase their starting points. You'll need to extract the Shared.pak to get those. They're located in
"Mods\Shared\CharacterCreation\ClassPresets\". You'll need Norbyte's EE Pak Extractor for that.
