What Amber does
Amber is a advanced-rarity artifact in Sephiria. In the inventory grid it occupies its own space, and any tablets you place beside it multiply the effect shown above.
It counts toward the Mystic combo — pair it with other artifacts tagged Mystic to trigger that combo's set bonus during a run.
