Called Spider-Lord here, need to change that. And then there's another one called Laghodessa which is level 42.
Anyway, it's level 38-40. Mix of heavy and plate armor (lagho is also a mix)
Screenshots:
Spider Lord (C needed plate, B? heavy)

Too lazy to do heavy mastery calculations, but you should have Rank A way before that anyway.
hm, I dunno what I was smokin' when I added the plate armor info in the guide, needs some fixing, doing now. /fixed
