When sharks get released in AO they should have a chance to drop a random item when killed in a similar manner to chests maybe a 1 in 10 chance to drop. Drop rates could differ depending on the shark.
Edit: Drop table will be shared with that of chests and merchants/smugglers.
Sunken gear could drop from white eyes at a 1 in 1000 chance.
A lot of galleons will be dropped and 1-6 random items could be dropped. Depends on how difficult vetex makes it to kill white eyes. Say if white eyes actively pursued boats and players compared to only spawning when a player is in the water. But not being too expectant then I would say guaranteed 2 items. Maybe even a ship part.
If you read, he said that it could be adjusted to actually make sense, and also sharks are known to eat things randomly so that’s not too far fetched, bonus points if its a magic infused shark
