In Mech for the Boss "Nethermancer Sepethrea" (the one with the 3 fire adds on Heroic)...
There is abit of luck involved to get this to work...
1. We had one person sit on the elevator before we started the event (one on the guys in the party were duel boxing)
2. When the adds targeted him to run after, they stopped moving - they didn't port him or anything
so, in the end the adds just sat there while we burned down the boss![]()
