Dodging

Clicking the Middle Mouse Button (pressing down on the scroll wheel) while moving causes your character to Dodge, becoming temporarily immune to most types of damage, consuming 1/4 of your maximum stamina. This excludes Spike Traps (and probably any other future trap) and poison from the Rogue's Dagger special attack. Activating dodge while standing still does nothing - the character must be moving in order to to dodge. If performed while riding a pet, dodging will make the character dismount.
