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

Immunity to Poison

Alchemy, Potion

Makes the drinker immune to all poisons but somewhat clumsy during strenuous action.

From the book

Made with 1 dr. of unicorn horn and 1 ct. each of powdered agate and jade, it makes the drinker immune to every kind of poison. The side effect is clumsiness: during combat, running or other vigorous activity he has a 10% (2 in 20) chance of fumbling or tripping.

Like every potion, it is brewed on a base of a pint of clear water, 1 dr. each of powdered gold, silver and copper, and 1 ct. each of seven powdered gemstones, for which an alchemist may substitute 2 drs. of Rare Earths. Brewing needs a mortar and pestle, a small cauldron or alembic and a furnace, and lasts a week; the fermenting mixture is unstable, with a 1% chance of mishap from the 2nd to the 7th day. Success is 90% plus 1% per level, to 99%, and the price starts at 400 G.P. Herbs with similar properties may stand in for scarce animal parts, but only if the base is doubled, and the chance of success drops by 25%.
