Hi, if you are having trouble on the easiest setting my advice would be to take it slow and try out different ways of appoach for hard to do quests or gathering new equipment. the early game is unfortunately one of the harder parts simply because your player characters are not fleshed out yet！
Since there's no easy way to redistribute attribute points, the distribution of them is utmost crucial. You should know exactly what your characters are supposed to do in combat and then build them the way to achieve that effectively. If the possilibities are simply overwhelming I'd advise to look up some guides and builds, and how to play em. Also knowing the carfting recipes helps a ton. You really don't need to min max or do everything exactly in order, the game allows for alot of freedom. If you feel like you miskilled just start anew with a plan made out for say lvl 1-10 for example.
Lastly, non combat-wise Id recommend getting certain skills and items early on: 1. loremaster for infos on enemies 2. walk in shadow/sneak to grab stuff 3. crafting/blacksmith to make/buff equip 4. spellbooks for skillusers asap 5. teleporter pyramid! 6. pickpocket for easy money/items. Hving ticked off that list should be enough to get you through early game on any difficulty. And the rest will only depend on how well your party synergizes in combat. Dont follow step by step walkthroughs, make your own adventure! This game's got the tools for it.
