I'm not aware of any way to fix this, perhaps the DEV would consider renaming all weapons and staves individually so that this could be done. I used to have a problem on my pdt/mdt set with pld using three dark rings. The good one is -6pdt/mdt dark ring, the other two offered -4 and -5 in their respective fields of mdt and pdt, so I had wanted to be able to swap out the two weaker rings depending on which set i was using, mdt or pdt. But as you know, this didn't work, I would have to keep one ring in my sachel so it wouldn't be equiped and repalce the good ring. Even using the wait command the system would equip both, but wouldn't know which ring to remove when switching to ws set and then to a tp set and back to a pdt or mdt set. my solution was to replace the inferior rings with the AV mdt ring and the jelly ring. Unfortunity, I would have prefered the three dark ring set because they were superior to the set I use now because they had no negitive stats (AV ring has +5 pdt while jelly has +5 mdt, this is the trade off for their corresponding stats)
