From the LAME readme:
- every spell now has a code at the beginning (magic school + effect + mastery level), your spell book won't be a mess anymore. E.g. ILi3: Candlelight
edit.
From the original Supreme Magicka readme:
Have you ever had trouble looking for the right spell just because you couldn't remember what it was called? The spell sorter feature sorts your spells so that they are displayed by school and mastery level and are not just thrown everywhere haphazardly. All spells have a letter and number in parenthesis in front of their names such as "(D3) Fireball". The "D" stands for Destruction and "3" means that it's a journeyman spell.
Not sure if Strategy Master's updated version still does this, probably does.
