Thanks for the answers!

One last thing: where in Thaumatology does it cover minor changes of specific spells? To clarify, I've skimmed the minor spell variants, but it's mostly from a GM perspective, whereas I'm interested in this from a player perspective (i.e. a player wants to cast Splashing Acidball and wants to know what enhancements or spell variants are needed; not how I as a GM could setup new elemental colleges etc).
