Description

Fragmented saw teeth left behind by automatons. Can be used for the Ascension of Physical characters.

Lore

It is said that the smelting techniques of the Architects allowed them to make chainsaws sturdy enough to split giant boulders. Such techniques have been long lost to history. "Boss Svarog says its blade is so thin that it can cut into the gap between molecules... What are molecules?"

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.
