Good stuff, thanks for sharing. One suggestion that comes to mind (if you have the time) would be to add a column next to the spell name that just says what spell line each one belongs to (Pet, Lifetap, Buff, etc.). This would be useful for anyone who may not be familiar enough with necro spells to know each one by name.

Bump: Added sheets for Magician, Enchanter, Wizard. It's now an all-in-one research sheet.
