Blizzard has revealed on Patch 10.1.5 Patch Notes that Priests will be receiving a new glyph that will allow them to speak Shath’Yar once again during Voidform.
This was originally the default behavior of Voidform, but it was usually a communication hindrance in organized dungeon and raid groups, so it was removed for Dragonflight. This glyph will restore this functionality.
This glyph will drop off N’Zoth the Corruptor, the last boss in Ny’alotha, the Waking City.
