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 Petrification

Alchemy, Potion

Protects against being turned to stone but weakens saves against heat and cold.

From the book

Made with 3 drs. of gargoyle's horn and 1 ct. of powdered jade, it protects the drinker from petrification attacks, though his saves against heat or cold attacks suffer a -2 penalty.

Potions grant temporary magical or spell-like powers, normally for 40 + 1-20 minutes. The base is a pint of clear water with a dram each of powdered gold, silver and copper and a carat each of any seven powdered gems (an alchemist may use 2 drs. of Rare Earths instead of the gems). It takes a week in a small cauldron or alembic over a furnace, with a 90% chance of success plus 1% per level (99% at most), and a 1% chance of mishap while it ferments between the 2nd and 7th days. Potions sell for at least 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%.
