So finally got around to getting two of these accessories to test them out.
So here is a screen shot proving that damage works.
As for the cast delay, the accessories also work.
The issue is that it isn't all variable cast, it has somewhere between 0.4 to 0.8 seconds in fixed cast delay, proven after I took my +6 Doram set on and off. The accessories work as intended, but the skill clearly is not if kRO indeed gets instant cast.
