Two-headed Silver Ring
A silver ring in the shape of twin basilisk heads. Wearing it increases your crit and fumble range by one. Multiple rings stack.
Sold by Mikhael the Merchant in Tveland for a portion of the buyer's soul. A trinket of the Two-Headed Basilisks; the wearer's luck swings wider in both directions, the world becoming both more lethal and more merciful at once.
