the best solo class I have seen is troll leather pants and armour with the best metal helmet you can make for max speed, combined with the spear and buckler. you can pretty much kill anything just running around and randomly hitting it with a spear, especially frost golems and lox. you just need to always have stamina potions at all times for when you really need a boost, other potions are not as needed. With this build the goal is taking the least hits possible in fights.

if you are up against an unbeatable enemy just pop the bonemass ability and you basically cannot be hurt even in the troll leather armour.
