Tanaan Introduction Instant Resurrection - Weird Levelling Opportunity (Patreon)

The Tanaan jungle introductory scenario that leads into Warlords Of Draenor, upon entry to the dark portal, gives the player a special buff "Khadgar's Watch". This is an odd effect that resurrects you with a timewarp animation if you die during the scenario. The "watch" then goes on cooldown for three minutes during which time if you die, you die in the normal manner rezzed at at  graveyard.

When the watch is activated a secondary buff appears, identical to the permanent Khadgar's Watch buff, only this has a timer which counts down. If this completes the player will be resurrected with full health and the player will be rezzed with full health, and the ability will go on cooldown (you'll received a three minute debuff).

However, if you right-click on the secondary buff before it counts down, you will resurrect on low health but with no associated cooldown. You can continuously resurrect indefinitely. 

The main use for this glitch is an approach I outlined in my first public levelling video seven months ago https://youtu.be/q0oD3CF3XOk?t=1851 .

Put simply there is an opportunity to grind experience in the scenario at a fast respawn location with the aid of a quest pet (Ariok the orc). In my 7.3.5 guide I took this section out because the scaling made survivability an issue for more fragile classes. However, with the watch glitch survivability is no longer an issue. 

In theory you could grind up to 100 just doing this farm as the mobs scale indefinitely. This is relatively easy to automate without advanced botting skills: at a bare minimum you simply need to cancel the resurrection buff and use aoe-Ariok will kill orcs for you.
