Oh nice, I killed this boss yesterday, so I have a fresh screenshot from it haha
The strategy consist on trapping it with WG/MWALL so it doesn't move, here: (this is the "bugged" spot you mean, however it will still teleport team, but a lot less)
The team should stay on NORTH EAST, safe from the UEs, and on the opposite side of the boss, meaning the chances of him retargetting are lower.
He can teleport everyone to the center of the room, though. Gotta be careful.
He will cast UEs that will deal damage to specific vocations, the UEs can deal 5,000 - 10,000 damage, so stay far away from him! Each vocation has a different UE damage, like this:
- Paladins should wear Energy Protection
- Druids should wear Earth Protection
- Knight should wear Fire Protection
- Sorcerers should wear Death Protection
Important points:
- As a knight, I used winterblade, he seems to take a bit more damage to ice, than physical.
- Mages should just use SDs.
- Before using his UEs he will scream the name of the vocation, so pay attention to that! For an example: KNIGHTS WILL DIE!
- He runs on RED HP, so EK should constantly use exeta res, once boss hits red HP
Thats it, I hope it helped!
