WoW Retail: Cast Spells While Suspended In Mid-Air (Patreon)

The great Lord Slaain was kind enough to send me a link to this video: https://www.youtube.com/watch?v=nrcLgyLtR-I&ab_channel=RiskyCB

In the video a talented exploiter shows how to use the "Fae Harp" toy https://www.wowhead.com/item=184489/fae-harp

to remain suspended in mid-air.

Most of the methods in the video are demon hunter focused, and I could not replicate them, suggesting they had been fixed. 

However, I did find that by using alter time (mage) and transference (monk) I could suspend my characters in mid-air. You simply cast alter time or transference while in mid-air, activate the harp, then cast alter time or transference again. This is potentially even more useful since it allows ranged classes to heal or attack, effectively from an invisible platform, where they cannot be attacked by melee classes.  This is game-breaking in arena.

Technically every class can do the same thing with the "ripple in space" Heart Of Azeroth essence from BFA, which is very similar to alter time. This works well in world pvp, but essences are no longer active in instanced content. Swapblaster also works.

The same trick can be done with mage ice block and certain other toys for limited periods, however this is the only toy which allows the player to remain suspended in mid-air AND able to cast. 

*This article may be updated as I am fairly certain there are other exploits involving the harp I have not discovered yet.
