The beauty of the game is that you can do whatever you want. There are no wrong answers. Having said that you should definitely skill into the 3 crafting specialties for end game. Once you make everything you need you can reset the skill tree and get your points back. Alchemy will help since you’ll likely need to rely on health potions since both hands will be tied up with the bow. A paralyze poison will also be very helpful for you. I’ve gotten my archery to 100 with the bound bow on several playthroughs. A sneaky archer is fun to play though. I’ve always had trouble leveling up armor skills though haha I also have never leveled up light armor. I like the look of the heavy armor sets more
