Let's see. Chukkle yours is fine, Gisk yours is fine. Both accepted. Prime, I would either like you to sacrifice lethality and make it harder to cure, or make it easier to cure and keep the lethality as a balancing factor. As is it seems a bit potent. Another note is there are very simple Magistra that can dispel most toxins though they take a considerable amount of time and concentration to be effective, like a couple hours of straight up sitting still in one place.
There are presently two ways to cure it and both involve Elia. You could kill her (challenging but not impossible) or yielding and asking her for the antivemon. The potency and lack of a cure is to compensate for Elia's small and generally weak attacks. She won't be able to puncture armor and will rely on avoidance and poison to finish off large armored warriors. But I understand your concerns so if I made the compromise by saying it can be cured by means of rest (retreating and seeking a Magistra for medical aid will) would that make amends? It gives a poisoned victim four hours to find a Skillful Magistra to begin purging the body of the toxin. Anywhere from a day or two will the victim be bedridden with a horrid flu as the body and the magic fight off the toxin. Does this sound fair?
