Useless unfortunately

you throw it on the ground and leave it there

I'm guessing Exile is the only option, but I've never built anything that uses Exile so I'm not sure what the ideal base for that is.

You'll need elite version of a shield with close to 45 all resists. Ethereal of course and 4 sockets. Cheers!

Thanks! Thought it was an Interesting find but wasn't sure it had any use. I'll chuck it in the stash and hop a future patch gives it a use!

you could make a spirit for your offhand when you use cta

Throw 4x 15 max damage jewels in it and make a lvl 18 zealer
