currently its very frustrating to get the correct boss for cloaks and enchants. the only way to sorta circumvent this is by using multiple characters, but even then u still have to win the 1/4 chance of getting the correct boss. if you only have a few characters or even just one, it could take days to get the correct boss to spawn, only to get screwed over by another 1/4 (2/4 with bbg) chance per drop.
so, to make it a little less frustrating, let us trade in other beast mats 3:1.
that way its still frustrating, but at least more bearable getting another spring not the right beast to spawn.
