*Outside of combat, a natural 20 does not mean an automatic success. It does grant a +10 to your total, but if the opposing check is higher even than that total, it will still win out.
*Catbat Points. Catbat points are an alternative to action points. To explain further, this means that if you are bestowed with the blessing of such a point, you have at your disposal some amount of DM favor. However, this favor is somewhat subject to whim and caprice. You may indicate a preferred outcome, or you may simply say that you invoke one and allow the DM to use her chaotically creative imagination.
