In a way, Underworld almost goes out of control in terms of scale, though if you like gathering stuff, then this is your game. Since you start the expansion at level 25 or higher, it doesn't make sense for the loot or experience to start small. So, before you know it, you're dishing out hundreds of hit points of damage for every hit, and amassing hundreds, if not thousands, of experience points for every minor kill, though you'll certainly need them, since it takes a mountain of experience to level up. And virtually every item in the expansion packs a slew of modifiers that can affect any of your character's abilities, meaning that you can spend a lot of time analyzing which combination of items to go with. Items can be upgraded or enchanted through the use of sockets, or by finding the nearest village smith and getting him to improve an existing piece of equipment.​
