Okay, I don't like the feel of Dead Magic and Wild Magic in Cerilia but for those who
might like it, I had a simple idea about these types of magic.

Sources have a base and are then modified by whaterer (dragon bones: +2 source; magical
cataclysm: -2 source, etc). So if a source falls below -3 (but recoreded as 0) is is
considered dead magic and if it rises to 12 or higher it is wild magic. Simple.
