Different type of mitigator, a post-trigger one?

[vicky_molokh]

Greetings, all!

Here's an idea that I'm not sure how to implement: imagine a Mitigator that doesn't totally negate the triggering of a Disadvantage, but rather 'turns it off' after it has already trigerred? For example:

(N)PC has some weird form of Epilepsy. (N)PC also has a ready hypo/syringe with an experimental drug that can stop the seizure. A seizure occurs. Another (N)PC approaches the epileptic and applies the hypo/syringe. One of the following occurs after the standard delay for injected drugs:

• The epileptic gets a reroll for each dose, at -1 per dose after the first per day.
• The epileptic gets an instant return to consciousness and control of the body, but repeated doses per day have side-effects.
• A reroll or an instant cure for this instance of epilepsy, but each next dose throughout the whole life has a chance to cause a permanent side effect (e.g. roll HT or gain a 1-CP disadvantage towards side effects).
• A reroll or an instant cure for this instance of epilepsy, but each dose throughout the whole life has less and chance of working at all (e.g. chance is reduced by some constant percentage per use).

How much would each of those cost?

Thanks in advance!
