Orphanim Eyes is going to be good on any frame with mildly high power strength because it is armor and shield strip that you don't need to actively stop and use for bigger targets. That said, I wouldn't exactly say its great on Rhino when he already has Roar to be able to ignore armor via Bleed scaling and shields crumble like wet tissue paper with any form of DoT damage to deny it the ability to recharge. I'd likely take something like Wrathful Advance to scale a melee approach to really lean into the DoT style that Roar already encourages for him.

Edit: Mirage enjoyers will absolutely love it though. Full Eclipse value and armor strip? Say less.

Personal opinion. Don't like it because it take long to fully strip enemies and the damage is not worth. Pillage can do the same but much better.

To be fair I mainly used it for it's slowing effect, not like armor stripping is that necessary for normal SP. I guess gloom does the same thing, but better, but Sevagoth is also a pain in the ass to grind in comparison to Jade.

The slow is the main selling point of Ophanin Eyes. Ophanim Eyes also doesn't really care about your entire build revolving around it like Pillage.

It's not replacing Pillage, but it's a welcome option among the other Helminth strips.
