Sanity System and Curing Madnesses

[Maelstrom25]

Perhaps I am reading it wrong, but it sounds to me like using the Sanity System from the Horror Adventures book, the only way to actually cure oneself of a madness (not just make it dormant) is via a Miracle or Wish spell. Does that mean you're pretty much stuck with all your dormant madnesses for basically the entirety of a campaign, or until you get access to 9th level spellcasting? That seems overly harsh.

Is this supposed to be used along with the rules for Madness in that same book? According to the rules under the Madness section, one can slowly cure their madness through rest or magic (much along the same lines as what is used to heal sanity damage in the Sanity System). So, does resting and casting these spells both heal sanity damage as well as decrease the DC of the madness towards curing the madness when it reaches DC 0? Do you have to do separate castings and announce beforehand whether you are healing sanity damage or trying to cure a madness? Can you only cure a madness when it is dormant?

I'm trying to determine what the connection is between the two systems and how they interact or relate to one another. Can anyone provide any insights or opinions on the matter?

Yes, the Sanity and Madness rules can interact with each other.

Horror Adventures, page 182 wrote:

After 7 consecutive days of uninterrupted rest, the afflicted character can attempt a Will save against the madness’s current DC. If she succeeds, the DC is reduced by a number of points equal to 1/2 the character’s Charisma modifier (minimum 1).

...
The character suffers the madness’s effect until the DC is reduced to 0

So yes, you can cure madness without Miracle, Wish or any other spells.

However, the sanity rules are not very balanced, at all. Me and my group used it to the point that our characters got totally broken and we had accumulated 4-7 madness-es each.
So we re-wrote the rules so that they could actually be used. Here's a link! Feel free to check it out, use, modify, etc!
