This system was originally created by Lord Blackfang on the Wizards boards in 2006. I updated it and modified it for better playability. This is meant to completely replace the Spell Points variant found in Unearthed Arcana, which is a broken piece of trash. Many attempts have been made to produce a good point-based casting system, and every one of them has failed miserably, all because of the same basic design flaw: a linear - or even exponential - increase of casting cost for higher-level spells. It may seem like common sense because everybody's doing it, but in this case, everybody's wrong.
