Editing Umbral Domains: Paltery Bards System (section)

=== Botching ===

Once you've rolled any given pool separate out all dice that rolled 1 or 2.  If more than half the dice in the pool rolled 1 or 2 then the roll counts as a botch.  Something pretty bad happens on a botch, generally even worse if *alot* more than half the dice rolled 1 or 2.

You may notice that it's possible to both get successes and botch at the same time with this system.  Such a combination of success and botch indicates that the character has succeeded at the thing they were attempting but has done so at the cost of screwing something else up.
