I have one of each wrist from the H3. Dendritic Acuity Bangle and the Dendritic Blood Bracelet. Today I equipped the Forgotten Bell - Wrists on the other Dendritic wrist I had. Each wrist now has a bell attached to it and it won't let me equip both wrists at the same time. I am getting a red message stating You may only equip 1 Regalia of the Bells - Wrist at a time. Is this intended to make it a lore-equip item when attaching the bells? I now have a wasted Dendritic item now that I can't equip both of them. Is it possible to remove the lore-equip tag on them or a way to be able to unattune the bell so they both can be worn again?
I believe it's because of the effect that was added to the item when you applied the bell to the wrist. You may have been able to use both IF they didn't have the same effect. YMMV (since I don't have either wrist to check if it's possible).
