A Useful concoction

A preventative elixir 

Designed for the Company of Fools game but of wider use I would think

 

This is a mundane potion prepared by the herbalists’ at large temples of the Caregiver such as the Great Hospital in Vayham. These herbalists, who are mostly ether junior priests of the care giver or anointed experts produce the potion in some quantity as it is useful in their work and can be made from relatively common herbs. There are reputed to be more powerful versions made with more exotic ingredients or ones which are specific rather than general.  Beyond the cult of the care giver similar potions are made in many places as making of them is not uncommon knowledge to the wider community of herbalists beyond those associated with the caregivers cult. It should be noted that independent herbalists who make these potions attract the special ire of the servants of the rot lord and being outside the protection of the care givers cult they are especially vulnerable.

It can be used as a preventative, and is often taken by Care givers working with infected patients to protect them selves, and as a treatment thought it is not that good a treatment and only works to aid at the point of crisis of the disease but it will work for all diseases.

As a preventative it adds +1d6 to the takers disease resistance for at least twelve hours after consumption, with the die being rolled individually for each potential infection. As a curative the potion ads +1 to any one roll made to determine the result of the crisis point of a disease. The potion tends to be dispensed freely as needed by the followers of the Caregiver but where it is for sale it would cost 10-20 silver per dose  and a dose is a sixth of a pint in a sturdy stone ware flask sealed with wax.. Multiple doses dont stack but may cause some transitory nausea,

As a campaign note it was used to dose all the party entering the Rot Lords temple under Vayham with the intent to exterminate the cult and destroy its foul works and was given free as it was to do the Caregivers work.
