There’s a new special effect cloak dropping from Aberrus, the Shadowed Crucible on the Dragonflight Patch 10.1 PTR. Voice of the Silent Star is a Very Rare drop from Scalecommander Sarkareth with a selfish special effect – capable of stealing the secondary stats of nearby allies in order to give them to you instead!
As befitting a very rare drop, the Voice has a rather unique appearance unlike most cloaks.
