Was there an equip more powerful than this?

Compared to what he had right now, apart from the Supreme Ring and the Bloodstained Badge, there was absolutely nothing that was as powerful as this cloak.

He could stealth and get behind his target before they could even react. At this point, he could use Cheap Shot to stun it for 4 seconds.
