How to do sanity in D&D.

[Infernum]

I am putting together a game where I would like the character to be able to suffer sanity damage for seeing stuff they aren't prepared for, but am unsure how to go about doing this. I was thinking of having them make will saves when they see or encounter certain disturbing or horrifying things but did not want to use the taint system from the hero's of horror book. I think I will institute a percentile set up for the side effects, with different charts for the different levels of the side effects.

However I am running a little short on time and would like the assistance of the GitP forum in this matter. I would like any and all assistance I can get in making up a sanity system and how to determine a sanity score and side effects. I am hoping to add a bit of mood to the game and it will fit with the aberrations and weird **** that will happen. I will appreciate any and all help i can get on this matter, thank you.

Doesn't Unearthed Arcana have a Sanity System? I'm not sure.

This'd be cool for my Aquatic campaign. You go crazy for every day past a mont at sea...

You could always use the Madness system from The Wheel of Time rpg. This can make characters unplayable though.
