The random spell you get from the Anima power toy where you can create a portal to the unknown should definitely be added to the list of Mage portals you can do!
Since mage has been ruined for DPS i’m the only mage that now plays in my guild which means the only one for Raiding and the only one for Mythics.
This means i’m always asked for a portal and usually i like to place a desired portal and then a random one on the top, we have a laugh to see who gets sent where. I feel this portal to the unknown would be great for this and would be awesome to have in my list of portals.
*On a side note it would be a good idea for blizzard to make mages better at DPS again as we are being left behind
