During the final battle the Dread Masters will recuperate on their thrones, and be given the ‘Unreachable’ buff to prevent damage. It seems they don’t want to give that perk up.
BioWare pledges to fix this trouble disturbance in the force ”before the weekend,” leaving the entire Dread Palace Operation a futile exercise for now.
”During the final encounter, when the Dread Masters return to their thrones to recuperate, the last Dread Master to return to his throne will not lose the “Unreachable” buff. This buff is intended to prevent damage, so you will not be able to defeat them,” explains BioWare in their Bug Reports message. ”We are working to get a fix out for this issue before the weekend, so please keep your eyes open for further information.”
The studio has been having some trouble lately as the initial Update 2.4 that went live was found to be stopping some from launching the game, with users left with little choice but to reinstall the MMO. There’s also been some discrepancies regarding Warzone commendations in PvP, with users short changed.
