Prepare Vexation (sage ability)
Prepare vexation is an authority-status sage ability that allows the mixing and making of a specific mushroom-based ingestive poison intended to kill the imbiber. This is introduced into consumables through knowledge of dosing.
The character must compound the poison, a process that requires a laboratory, time and the various ingredients of the poison. These specific ingredients come from mushrooms that can be easily found by the character in the wild and distilled to produce the asphyxiant and arsenic required. The character's full attention is required to produce a result. A "batch" is sufficient for 4 doses. Vexation cannot be made in smaller batches, nor can it be made in less time than indicated.
Preparation and Effects
Ingredients: 10 grains asphyxiant, 4 grains arsenic, 1 oz. four thieves' vinegar, 3 oz. gum ammoniac; 6 days to compound.
Once consumed, the first effect is a strong blow to the digestive tract, causing 3-6 damage. This is followed two rounds later by another effect, causing 2-5 damage. If this doesn't kill, the imbiber makes a saving throw; a success will mean that the poison has run its course; no more damage will occur and within 6-8 hours, the imbiber will actually feel better, with 1-4 hit points being restored.
If a saving throw fails, then a third effect will be felt after 5-20 additional rounds, causing 1-3 damage. The imbiber will then suffer 1 h.p. of damage about 20 minutes later, and 1 h.p. of damage an hour after taking the poison. This is all the suffering that vexation is able to bestow. It is rarely sufficient enough to kill a strong, fit levelled person, but it is effective against common folk and as a means to kill vermin.
