I was just thinking about the useless drops you get from the 3 new beastmen kings, and then it hit me. There has to be a purpose behind these items that drop from mobs this troublesome, and there's only one thing that could use weird and hard to get items.
I suspect the new Relics that drop from Nyzul will use these as upgrade items! (Dramatic chipmunk)
Seriously though, its all I can think of.
