Exactly which new abilities are we talking? New Heroic abilities which spend our resource?
For Obsidian, these would be new passive abilities. Specifically, Primordial Strength, Mighty Leaps, Brawny and Runic Carving.
But you can swap anything in your character sheet and have a fully fledged 1st level character now. Tutorial is over. It’s the final battle.
PS: As long as you maintain the same Ancestry, Class, Subclass, Kit, and Career.
