Editing Alchemy for Runequest (section)

==Formula==

A formula is a series of instructions, often memorised or written down, that allow a practitioner to create a potion or powder or paste to produce a specific effect.  Some formulae have fixed effects e.g. smoke bomb and others have grades of effect or potency (POT) e.g. poisons, acids, healing potions etc. Each formula will be for a specified POT of effect.  These formulae are often very closely guarded secrets and only available to initiates of specific cults or to members of Alchemy guilds.  If available, the cost of a formula is often very high, treat the multiplier for the formulae as a minimum for a trusted friend.

Note, that whist in here only one posions and healing potions have been listed there are also formulae that deal with the opposite effect.  i.e. antidotes and damaging potions and potions to cause diseases.  It can be expected that the healer cults will know of any curative potion whilst the alchemists will know both good and bad sides of any effect.  The cost of the opposite effect is always the same as the original.
