Also, what's the deal with bloody chests? How do you open one? What kind of key is needed? Thanks yall.
I'll answer the second part of your inquiry since I'm not too sure what the first part is implying.
Bloody chests can only be opened by Bloody keys, which are obtainable from either Rev caves or Crystal dragons/demons. There are also a few known spots throughout Alora that spawn these keys. Locations follow: Demonic Ruins, Rev caves, Axe hut, Ice plateau, & Pirate's hideout.
