The Bone Crucible | Trial of the Feather

Cast threeChoose a School you hold at least 3 of. Cast them with 55 gold: the three Sigils burn to ash, the gold goes to the unknown deity, and the fire gives back one Sigil of a different School.

The bones decideWhich School returns, only the bones decide. The odds of each are shown before you cast, and it never gives back the School you fed it.

Sigils you boughtSigils bought on the Market may be cast too. What rises from them keeps their lock: forge it or cast it again at once, but it cannot be sold until a day has passed. Anything else the Crucible makes is yours to forge, trade or cast again.
