When I finally moved to unshackle Orpheus with my hard-won Orphic Hammer, I was much alarmed when unshackling strike did nothing. I slammed the ability dozens of times agaisnt the containing crystals and even against the sphere itself. I could have easily wasted a half of an hour flailing, before reading online that I needed to use the hammer’s base attack, not the ability. This is not ok.
Either the ability needs to be fixed and capable of destroying the crystals, or it should be removed and changed to a passive ability on the item. Be careful not to break the interaction with Hope, as unshackling strike worked there.
