Omnicatalysts are a suite of chemical compounds which can vastly accelerate a wide range of chemical interactions. They are rare, but of tremendous use to biochemists and phsycians. Medicaments doped with omnicatalyst typically become much more effective, as the desired biochemical reactions are stimulated in its presence. Omnicatalysts can also be used in a more sinister fashion, as toxins and venoms doped with omnicatalyst are considerably more lethal as they overwhelm an organism's natural defence mechanisms.
Omnicatalysts are a type of Exotic Reagent - an Exotic Substance related to Corporeal Science. A physrep of a sample of some kind of powder can be used to represent measures of this substance, smaller samples can represent one or two measures, while larger physrep samples can hold more. Please don't use powders that are dangerous or messy - coloured fine sugar is probably the best.
A measure of Omnicatalyst can be applied to any single measure of an injectable Medicament. Applying a measure of this substance will empower the medicament's effects, increasing its benefit (or penalty). As a minimum, the Omnicatalyst doubles all numerical values on the Medicament, except any that refer to durations or time. Some Conditions will specifically note what will happen when they are treated with an Omnicatalyst-doped substance.
Examples of operation:
Omnicatalysts may have other effects when applied to certain substances that don't use numerical values on their effect lammies - Radiation nanosponges might purge more radiation, etc. These effects are difficult to predict however - if you have taken a Medicament doped with Omnicatalyst and it doesnt have any numerical effects, then you can decide if the Omnicatalyst has no effect, or alternatively you can approach a Ref, who may decide that it has an additional effect (but may not). Omnicatalysts are delicate and complex mixtures of compounds that are impossible to manufacture completely consistently.
As with all Exotic Substances, a character with at least 1 rank in the relevant speciality (Corporeal Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Omnicatalyst to a Medicament. After this roleplaying, they should unpeel the sticker that represents this substance, and stick it to the lammie of the Medicament, modifying its game effect.
