An alchemist shapes a clay golem beside copper furnaces and a homunculus in a jar, with whales drifting past a sunken city beyond.

Essential Lodestone

Alchemy, Essence

A dull gray stone whose magnetism can raise a protective force field or dispel one once per day.

From the book

A dull gray stone weighing an ounce. Once per day its holder can draw on its magnetism either to raise a force-field 10 ft. in radius that lasts an hour, or to cancel a similar force-field.

Like every essence, it is drawn out with a quarter fluid dram of alchahest from 12 drams of its base substance, using an aludel, an athanor and a full laboratory over at least two weeks; success rests on a save vs Will. If it fails, a percentile roll of 10 or less means a mishap on the Alchemical Mishap Table, and in any case the whole procedure must be repeated.
