From publisher blurb: One of my earliest D20 System PDFs was devoted to the idea that wizards could amplify the power of their spells by adding special arcane spell components to the casting ritual. 101 Arcane Spell Components was one of my many hits well over a decade ago, so it should come as no surprise that I decided to tackle the subject again. Where today’s approach to spell components deviates from my original work is in two very specific ways: These “rules” are systemless in nature, meaning that the gamemaster must craft the actual in-game effects for each of the described items. This isn’t as complicated or challenging as it may sound, though, because I do provide some loose guidance. I’ve given each of the described arcane spell components a full page so that each can include suggestions on how the items may affect spells, separated by school of magic. In many instances, a component only affects spells of three or four different schools of magic. As always, adjust the specifics to suit your needs.
