Multiplayer and monster special loot

How does multiplayer interact with special monster drops exactly?

Would joining a multiplayer game and farming with friends help the drop rate of items like Alkamos’s rings at all?

We’ve noticed that things like aether crystal clusters, which have a 100% drop rate for some kind of aether crystal item, will only give an item to one of the players in an MP session. This has me wondering if being in a multiplayer affects the chances of monster specific loot at all. As an example, one of my pals is making a cold reaper, and wants alkamos’s rings. If another player and I also join the game and kill Alkamos, are we looking at a ~1% chance for the ring to drop period, and it will be assigned to one player, or a 1% per player rate? I would naturally think the later, but based on how aether crystals behave it seems like it might be the former.

One roll for the ring to be generated and then it’s assigned to a player.
