Retrosum

Retrosum is a Utility spell that warps the caster back to a location where the spell was previously cast. It is obtained during the quest Secrets of the Past at Year 8.
==Description==
"Cast to store your position at a moment in time. Casting the spell again will rewind time and place you back where you were."
==Notes and Trivia==
* The stored location is visible to everybody, so opponents can place traps there.
* The stored location expires after 40 seconds.
* You are able to cast other spells in between storing a location and warping to it; you will have to reload Retrosum, but this is not a problem due to its very short cooldown. This allows you to warp across great distances by using mobility spells after storing a location.
