I noticed that the Mooncande Mender's Ring of Rohan has the same proc as the Hat of the Erebor minstrel. They both have a 15% chance on any single-target heal to apply a heal for 815-1165 morale to fellows within 20m. Do their chances stack? Do I have a 30% chance on any single-target heal to have either of them proc? And do they share the same CD timer, or each have their own? Sorry if this was asked at some point already, and thanks in advance for any help.
