So with this new world event came new rifts, and with that a new way to level
The secret is you need to find a water rift named
:From the Abyss:
Its the one that starts with lots of treasure chests in the middle.
Anyway get the rift into the 2nd stage (you will have the goal of killing 4 water elementals)
Kill only 3, as there are usually 3 close together ones and 1 thats off to the side.
Keeping up this last mob allows the rift to continue spawning adds that give 1% of a level per kill with only 1.4k hp (in a level 35-36 rift) I have tried this on several toons, within different level ranges and this brings true for all zones ive tried so far.
Happy Leveling
