(But not a "lvl 7", etc, just "A slot".)- Spells have a difficulty DC that is also related to their drain.- If you make your Fortitude save, the spell goes off. It may even reduce the drain if you do it well.- If you don't make the save, you must make a skill check to keep control.- You can reduce the drain by; saying the name of the spell (Fire-BLAZE), turning the spell into a whole round cast, or making it even longer into a ritual. If you are really good, you just flick your finger and it goes off.- Also rules for anime-esqe spell countering and combining.Sounds fun.- Feats are included.+ Class conversions for 3.0 and 3.5.+ Spell conversion guidelines.+ The book is also designed if you have an idea for a "Magical Girl" (Sailor Moon) type campaign in mind.+ Also can be used in d20 Modern, or d20 Space of you wish.
