Walking

Walking refers to a class of status effects that allow units to pass through certain objects in the environment. There are four types of walking: Unitwalking, Treewalking, Cliffwalking, and Buildingwalking.

Unitwalking

Unitwalking allows units to ignore collision with other units. Unitwalking is particularly useful in that it prevents you from being blocked by a group of creeps while chasing or running away (known as the dreaded "creep block") or from causing collision problems with friendly units, especially in a narrow pathway. Most forms of Stealth also grant Unitwalking.
