Power Components

The Dungeon Master’s Guide presents this optional rule as an alternative to spending XP on spells and magic items. Instead of using XP to power a spell, a spellcaster may substitute a special material component. These “power components” are rare and very valuable, and might even be a secret known only to a few spellcasters.

I wanted to use this option, because I never felt right about spending XP for anything other than their intended use in gaining levels. In a search for some recommended components, I ran across the best article ever printed regarding power components in Dragon Magazine #317 – March 2004  It was in an article called “Eye of Newt and Toe of Frog”.  Here are the suggested components for spells and magic items from that article:
