Hey!
Last night doing mythic keystones with my guildies we found a bug in Neltharus that allows you to get an infinite copy of the shield you can pick up after defeating Forgemaster Gorek if you are a blacksmith.
The bug works this way: Person who is blacksmithing picks up the shield and right as the cast is finishing, an Evoker uses Rescue on that person. For some reason, this allows the Evoker to have an infinite copy of that shield and allows them to spam it, dealing millions of dps.
I have logs and a clip of this happening.
Here is the clip of the Rescue.
Here is where we realized the bug in full.
