Okay, so this is a 80% of the time exploit that also relies on RNG. I came across this exploit while my guild was working on progression on Heroic LK 25, and having to wipe maybe 25+ times in a hour.
If battling again Lich King, at any level (heroic or regular), you can actually leash him, and survive the encounter without dying to a wipe. A few details are required that I've experimented with.
- Must be one of the last standing people in the raid
- Clearly must be 35-40+ yards away from where the LK was/is fighting people
- Nobody can be near you, unless it's another class that can vanish and/or fade completely dropping their aggro.
- I've survived while having Necrotic Plague, but only because my class can dispel it.
- All the furthest tips of the throne can be leashed on, for greatest results. I have done it on top of the thrown itself, but i can't support equal results as this method.
Included is a diagram of a way this could work:
Good luck!
