Description

Black Tide Creatures' core crystal. Can be used for the Ascension of Physical characters.

Lore

Truly, the followers of black tide appear in countless forms and can reliably be identified by their crystals. Yet, no one realizes that what seems to be the core is, in truth, merely the "outer shell." "I saw a sea of crystals, and then — the relieved smile of the physician."

Farm it smart

A BOSS material. The biggest pain: weekly bosses cap rewards per week, so this is often the BOTTLENECK that traps a character at the 70→80 ascension. Only fight the boss dropping mats for the character you are ACTUALLY building — do not spread thin.
