Halondrus Phase 3 Bug
Starting on Friday and continuing until Monday, players have reported on reddit and the official forums that Halondrus has some graphics issues in the last phase. This seemed to work fine up to last Thursday, but had issues over the weekend, making it much more difficult for groups to defeat this boss.
You can see a video of it this bug below from YouTube channel Springbro:
The Mythic mechanic, Volatile Charges, cannot be seen when it’s dropped on the floor and all the Planetcracker Beam are invisible in Phase 3 of the encounter making it much harder to complete and probably near impossible on Mythic difficulty. However, it is possible to get glimpses of these abilities if you move your camera around and find certain camera angles that allow you to see them.
It’s clearly not intended, and hopefully this will be fixed soon (if it isn’t already fixed)!
