Since i dont have time to get on ptr these past weeks im curious if someone could explain 2 things for me.

the 496 "token" so to speak. it says it drops from random mobs on the Timeless Isle, is this one per week only or can i farm a full set?

The 535 "token" will drop from some rare. how rare are these? is it IoT rare rare, or more like galleon in 5.0?
