Set bonuses

What the set grants when the team wears enough pieces of it.

Increases the equipping character's ATK by 12% for 12s when they trigger a Stellar Glimmer reaction or deal Stellar Glimmer reaction DMG.

Max level 20

Sands of Eon

Foundryman's Calculus

He knew that, unlike the heat at the heart of the furnace, the workings of power could not be controlled by the simple pull of a lever or the press of a button.

Max level 20

Goblet of Eonothem

Foundryman's Magnanimity

He knew that, unlike the flame at the heart of the furnace, which would continue burning indefinitely so long as it is supplied with fuel, friendship was far more fleeting.
