Best MI's Ring to Replace Open Hand/Closed Fist

As title says, i want to replace (if viable) these mythical rings for some GG MI rings.

Build: http://www.grimtools.com/calc/0V0O692m from Autentist.

What’s the best MI’s i can get for this build?

Best regards!

Forcewave builds want cast speed, right? The bloodsworn signets have 8%. With celerity it’s about 15%. And then you can get a green prefix.

You might want some reflect protection, this build is quite RIPy because of that

I’m curious what this build is actually aiming to do. The DA seems excessive and some questionable choices are seen in gear and devos.

Generally if you can fit open/closed in a build when there aren’t other legendary rings to shoot for they’re the ideal option for what they give.
