Ok so this is my first post on here since its the first thing ive found that is actually a good exploit, im not sure if its a re-post but i doubt it.
Ok this is what the exploit does, it allows you to start the encounter off on the HP that you left the boss on the previous encounter.
Explaination:
Ok so say you have Halion on 50% (or what ever percentage you want to resume the fight on), all that is needed for you to do is let one person reset the fight (with invis or vanish) and the boss will stay alive while letting you go out of combat on the same HP you left him on!
You rogue or mage then only has to res a member up with their engineer kit (a healer ofc) then they resurect the rest of the raid and resume the encounter from the % you left it on.
For this to be a ble to work ot is advised that no one in the raid releases their corpse and all wait for a ress.
I realise there is a low % of you being able to perform this exploit, since the engineer ressurect kit might not work correctly.
This might also be possible with a flask of invisibility not tested it yet.
