id say

Earthquake brought a bugged VS, two true VS were up at the same time, both dropped staffs.

sim repop script still has old versions of mobs and their loot tables i.e. CT 1.0, draco 1.0, VS 1.0, innoruuk 1.0

This isn't a troll but who cares about how often a gnarled staff drops?

I'm no rocket scientist... but if I had to guess, my guess would be wizards.

You win!

PS: us wizards appreciate this.
