I’d second the vote for explore, and then maybe cooking or foraging. Exploration helps you move quickly, which may help in travelling to gather supplies in the future; foraging will help you gather herbs for cooking, and cooking will allow you to make food that boosts xp gain which in turn will help you get stars in other skills later. They’re definitely more of a “skiller” set of stars to have, and not really combat, but you’ll gain combat as you go regardless, and being able to move fast and cook good food are definitely helpful
