Seeking some advice for a Noob. I'm on my first run through PoE II, having gone all the way through PoE I once. I've just got Serafen as a companion and I spec'd him as a barbarian because my main character is a cipher. I can't work out how to make him do anything useful! I never played a barbarian in PoE I and that's probably part of the problem, but I'm pretty confused.
* He comes with a battle axe and a blunderbuss as his first set of weapons. When I try to send him into melee he just shoots the blunderbuss. What's up with that? How can you have a ranged weapon and a melee weapon in a dual-use setup?
* If I take the blunderbuss away and make him go into melee with the battle axe he seems really useless and gets flattened really fast. I could give him a shield and a suit of better armour but I read that barbarians are best without...
Any advice? How can I make him worth keeping around?
