Description
Advanced level-up material for Traces.
Lore
No matter how many bodies it steals, its wish remains unfulfilled. Like those who seek the medicines of immortality, it craves an imperishable vessel, one that will rid it of its fear of destruction. And yet, it knows this is a dream that will never come true. "I have seen countless worlds devoured by The Blemished One's conflagration, and I was one of THEIR flames. I danced at the twirl of THEIR fingers, keenly aware that should the fuel burn out, this fire will also extinguish..."
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.
