This is the exploit on how the guild called Exodus killed Yogg-Saron +0/-4 (Hard-mode with no guardians up aka Alone in the Darkness Achievement).
Update: Exodus got a 72 hours ban for exploiting this, as you can read on MMO-Champion: Yogg +0 World First Kill - Exodus Suspended 72H.
How it works:
- Give a Holy Paladin Soulstone
- Send in two Paladins (One Holy, other can have any spec) with the Soulstone in the Brain room. In addition 1 or 2 warlocks with Soulstone
- When your are at the brain the Holy Paladin uses Divine Intervention; the Warlocks Hellfire themselves
(Update: Before you flame: Divine Intervention doesn't work anymore, read on)
- Let the Holy Paladin and the Warlocks wait until the Induce Madness channeling is over (You can see it in your Deadly Boss Mod (DBM) or BigWigs when he’s done with the channeling of the spell) and resurrect with Soulstone. (Druid’s Rebirth will also work)
- The Holy Paladin has to buffs himself with Righteous Fury in order to gain 90% more agro and uses a Runic Mana Potion
- Now the Holy Paladin has to spam heal on the Life Taping Warlocks , the immortal guardians will agro him (the Holy Paladin) and go in evade modus because they can’t reach him
- The damage dealers outside can just focuses their dps on Yogg-Saron until he’s down.
The second exploit
The second exploit works as following:
I have done YS 0 legit kill, but there is an exploit around that requires minimum effort. The method OP posted is FIXED, the way that people expect Exodus did it was that they had a tank taunting the adds. What the tank does then when he has agro is to run in and melee Yogg Saron. This will cause a Knockback which bugs up the adds and you get an "Evade". What happens then is that the adds "falls" through the ground, thus despawn. This means that a tank can get rid of all the adds, and every dps can focus on YS. The only issue here is that the tank has to take an initial hit or two, but this essentially makes P3 as easy as an old tank and spank Molten Core encounter. This method is extremely easy and worked as of 28/6-2009. I don't encourage you to do it though, since Blizzard is probably going to ban people hard for this.
