The Experience Bar
Some purple has also appeared in the experience bar that runs across the
bottom of your screen above the action bar. Mouse over it to see the
reading, which tells you how much experience you have and how much
experience you need to reach the next level. Each time you make a kill,
explore a new locale, or complete a quest, you earn experience, which adds
to this bar. When the bar is full, you gain a new level, and your experience
bar resets to zero, while the amount you need for the next level grows.
Looting Your Kill
Turn back to the monster's corpse. Sparkles of light drift up from its body.
That means you can loot it. Mouse over the corpse, and your cursor
changes to a bag. Right-click on the corpse to open up the loot window.
Inside the loot window should be some items. If you killed a humanoid
monster, such as a kobold, you would find money inside the window. If you
killed a beast, like a wolf, you might find wolf parts. Keep in mind that you
won't always get loot from a kill; some monsters carry nothing.
Right-click or left-click on the items in the loot window to pick them up.
When you pick up the last item in the loot window, the loot window closes,
and the sparkles disappear.
As soon as you loot the corpse, open your backpack. Inside one of the slots
you will find the item you just looted. Multiple items will take up multiple
slots, unless they are of the same type, in which case they might stack.
