[Beta] Where do we get kraken eyes, legendary gems and void roses?

[eX_ploit]

I know I can buy them from night merchant in small quantities, but what's the proper way to get these items? If there is no other way then it's pretty dumb.

[Oragepoilu]

I went over lv20+ in the void but never looted any of those, only finding them trough the merchant. (tested the 03/09 might change in the future)

There was a bug that caused Legendary Gems and Void Roses in particular to almost never drop, but we have that fixed on our end already!

Void Rose: Found on the Void, similar to how Voidstone spawns
Legendary Gem: Dropped by the new 3 bosses (Slime King, Skeleton King and Dark Beet)
Kraken's Eye: Found by fishing in the Void, using a Fishing Rod
