This boss is still broken, almost a year since it was "patched".
patches 7.2.1.2851 - 7.2.1.2854 were implemented on 25th October 2018 - Known Issues :
- Vale of Rites / Boss Marissha: there is a problem with the boss mechanic and Crystals are not spawning. This is known bug and was reported to Runewalker, so we can fix is a soon as possible.
It did not need a patch in the first place and it makes the instance now pretty boring because if you are unlucky you have to kill 3 red crystals every time the boss disappears. Which can also cause the boss to enrage if you lose the RNG lottery. Is there any way to revert this boss back to how it was before these patches?
