Instructions
Socket a Phase Shift rune into any piece of your equipment. This will give you the ability to use the spell.
Activate the spell within your user interface. Use your cursor to click anywhere on the ground within your line of sight. For example, you cannot teleport around a corner or behind a wall. You can only teleport to places that your character can see.
Wait a few seconds for the spell to be cast. Your character will then disappear in a flurry of magical lights, only to reappear on the spot that you clicked on earlier.
