I really like the Barb, they have many funny skills...Find item is one of my favorites - obviously, since I only play MF-barbs
@Silver Knight: Hello and welcome to the board
Regarding the henchmen, I often play with a Merc, they are actually quite useful sometimes, but they need attendance like babies. First, you must equip your merc with the best possible equipment you can find save that you use for yourself. Keep their resistances and defence high, and make sure they have plenty of life-steal. Second, you must be quick to feed them with healing potions all the time, personally I always use the shift-number key - that's much faster than using the mouse.
Wirt's leg is needed for something special, later...after you have beaten the final boss. But you don't need to save it in your inventory, since you can just pop back to Tristram and get a new one later when you need it. I'll tell more if you want to get spoiled!
