We was 3 paladins killing him because they needed the loot <3 And soloing a boss can take up to 1 hour (lol)
How to solo Zul'Jin and Hex Lord.
First you will need to be in a raid group(Doh)
Then you need to run to Hex Lord and find a safe spot then you should let you die and then release spirit. Walk a little bit around to you can see your corpse and then spam the macro: /script RetrieveCorpse()
You need to stand on your corpse while spamming the macro.
Now clear the trash around Hex Lord. (Trash mobs is really easy)
Now you need to pull Hex Lord (Make sure you got something that makes you run a little bit faster) Now run outside the building to here:
Now run all you can away until he gets stuck some place. And when he gets stuck you can ONLY MELEE ATTACK HIM. You can only use seals and AOE no spells like crusader strike.
IF you want to Kill Zul'Jin its the same way.
Clear trash to zul'jin mount up pull him and run to that spot and he should get stuck
I failed if this is posted before but i found the bug myself.
