Hokay, that was way long. I don't have it in me to proofread it thoroughly, so someone just poke me if I made a rediculous spelling error in there anywhere.
The warding:

-has a base of mundane herbs that do nothing by themselves, but absorb and bind other ingredients. (40%)
-has a single dose of Breath of Madness (20%; poison info copied here for ease of reference):

Breath of Madness (Lichen Dust; inhaled; DC 15; 600 gp)
Description: This powderized lichen is popular in Arlanche, where many of the inhabitants carry it in snuffboxes and claim that minute pinches of it induce hallucinations and the most wondrous sensations. Arlen, who saw many of them sniff themselves into a nightmarish stupor, was unimpressed, but took a large glass vial of it, thinking that it might be useful as a weapon in concentration.
Effect: 1d4 Wis / 2d6 Wis
Upgrades: None
Modified from:
Insanity mist
-has one ounce of Fenris' blood to bind the liver to the other ingredients (10%)
-has several ounces of minced Fenris liver to provide a primary olfactory ward against the Witches. (30%)
The potion created would be used as an incense - poured over a pot of coals, it is intended to provide a cloud of smoke that would severely hamper the Witches. The smell of the liver of their own creation should repulse them while the lichen dust confuses the senses and thoughts. This would hopefully be useable both defensively (to repel them) and offensively (to set up an ambush of tooth-tipped arrows, perhaps).
Modified spell coming sometime later. I is all writed out for now.
