I am trying to throw together a custom character for a friend as a gift and I'm in a bit of a hurry, so bear with me if this is stupid, poorly researched or otherwise annoying
How is this for balance and power as a special ability:
A madman's insight
Whenever N.N involuntarily loses sanity without going insane, he immediately gains one clue token.
I am thinking only loss here, not cost from spells or encounters/effects saying "you may spend" or similar. And not 1 for 1. Never more than 1 clue at a time. Could probably even be "once per turn". This is not a very serious creation, but I expect to play with him a couple of times, so some balance would be good.
