Science (Mumbos Geography) is the rating of a character's general knowledge regarding the geography of the worlds in the Mumbos System. This skill is regarded on a scale of 1-10 and any progression bonus beyond 10 has no really in-game merit aside from an extraordinary knowledge of Mumbos Geography. For progression bonuses under 10, the character must roll against a Difficulty Roll when trying to recall subjects related to the geography of Mumbos or recall where and how historical questions can be answered. Failure can only be rechecked at a Game Master's discretion or if the character receives assistance from someone that has an equal or better progression bonus.
