Alchemist's transmutations of various Essences into other Essences.
High-level alchemists can also perform transmutations on elemental materials and some metals for use with other craft skills. Arcanite, which is used in high-level Blacksmithing recipes, cannot be mined – it can only be transmuted from Arcane Crystal, which is derived from Thorium. Other transmutations are possible; see the recipe list below.[1]
Before an alchemist can perform transmutations, he or she must create a Philosopher's Stone. This stone must be in the inventory or equipped to perform any transmutations, and it is not consumed when a transmutation is done. Iron (and lead), gold, silver, and mithryl can all be transmuted into gold, true gold, alchemical silver, and truesilver respectively. Titanium also must be transmuted from Titanium Ore.
