There are also sometimes monsters inside, but you can just kill those.In Diablo III, you can use certain parts of the terrain to your advantage, so keep an eye out for those. There might be weak walls you can topple over onto enemies. There might be chandeliers you can chop down and drop on bosses. Explore, explore, explore. Just think, what if that chest you missed had a legendary sword in it?Don't expect to be able to customize your character's body type, facial features, or any of that sort of thing. You pick your gender and you pick your name. That's it. The monk is a specific monk, rather than one monk of many like you would see in an MMO. Your visual aesthetics will change based purely on the quality of loot you have.The meat of the customization comes in with which spells you choose to use and how you rune them. In my combat example above, the monk is using Fists of Thunder and Lashing Tail Kick. You don't have to use those; Diablo 3 Gold players have other options. You can use Deadly Reach to generate your resources and Tempest Rush to spend it. Other options are available! From there, your spells can be customized to carry other effects with items called runes. It's a bit like choosing your Mists of Pandaria talents or glyphs. The game will teach you how to use these when the time comes.
