I’m fairly sure Jaithys is absolutely massive.
I have a female Night Elf who uses this polearm. It is absolutely gigantic. It towers over her head by about 5’.
I have no idea where I got it from. None of my characters ever set foot in the raid.
Probably from a Timewalking weekly chest that gives you raid loot.
It’s a mystery. I am now vaguely remembering a character getting a weapon with a really important sounding name.
