Capture charms are the game's real scarcity, and today they come from
tapping a recipe.
Here you feed cores in one at a time. The pot tempers the whole batch: every core becomes a
charm at whatever tier you reach, so a hotter pot is worth more per core, and past the line,
every core you add might crack it.
You can never lose what you put in, a crack banks the batch at the last tier you passed.
The only thing at stake is how much you leave on the table.
