A Touch of Nightshade
This ritual allows the thaumaturge to poison a single victim by her slightest touch. The caster must anoint his hands with the bitter extract of nightshade before conducting this ritual.
System: The victim rolls Stamina + Fortitude (difficulty 8). With three or more successes, the target is unaffected. With two successes, the victim feels nauseous and queasy for three nights and increases his difficulty by one.
Errata: What happens with one success???
