New (old) Spells

I was digging through some old burned disks I had, and found a .txt file from a long time ago. Probably left over from when I was backing up my three and a half inch floppy archive on an older computer. Well on that disk, besides finding a specialty cleric class for 3.0 D&D, I found some spells that dated back to my campaigns in highschool with BEMCI. So yeah, here's those spells plus one more that I've made in the interim. The formatting has been altered to fit with the style of OSE.
If you're wondering the newer one is Seal Magic, which was needed for a Dragon Quest I thing I'm working on.
