Circulating Merecaster is a Merecaster of equipment in Torment: Tides of Numenera.
Within the endless loop of this strange alembic, golden fluid froths, fumes, and then precipitates back into the boiling beaker where it began. You cannot quite trace the pathway the substance follows. It almost seems that it is not a liquid at all, but rather some kind of organism endlessly and agonizingly transmuted within the unbreakable confines of the device. The merecaster puts you in the role of a man afflicted by the Iron Wind and you ultimately choose to whom to bequeath your estate.
