Philosopher's stone

The Philosopher's Stone is a lifetime reward in The Sims 3: Supernatural. This object allows a Sim to turn portable items into gold ingots as well as allowing the household to summon playable ghosts. However, there is a chance that the Sim will fail in the attempt to turn the object into gold and lose the item permanently, or worse, die by turning into gold. Should a Sim be killed by such an accident, the gold statue may be sold for a hefty sum, and can be named by the Sim killed in the action, should the Sim be revived.

Transmutation looks quite inefficient, as gold ingots produced by an individual action have a value of around §150. This seeming inefficiency is compounded by the risk involved in the transmutation (although one could exploit it by giving the Sim a Death Flower, reviving the Sim using the Philosopher's Stone as a playable ghost, or giving the Sim doing the transmuting either the Unlucky or Loser trait), though the technique relies on having the ghosts (or the protected Sim) transmute gold in your Sims's lot to get an infinite income of gold statues worth §50,000 (which runs on the assumption that the player has enough conversion materials to cause the accident), sometimes as much as §62,500. This does have some value: things with no value such as old newspapers, potions, seeds, etc. can be turned into gold ingots. In addition, converting things like old newspapers also allows a Witch to turn gold ingots into something else with the transformation spell.

The ghost of a Sim killed by being transmuted will be gold.

Player Notes

 * Using cheap items, like scraps or dirty dishes are better as they're cheap and barely beneficial.

 * Can be acquired by completing Master Alchemist opportunity chain. Available after reaching alchemy level 10.
