At the moment, I packed both age and nation into same column, and think it's probably a good idea. Even Machaka, which only exists in middle era, is Machaka2. Should probably be 2Machaka...

For spells, I suggest categorizing them by their purpose. Later, when I grep things, I'll want to filter spells which let me devastate enemy provinces, buff my provinces, etc. I don't like idea of having both Forest Dome and Seeking Arrow in same category.
rituals:
- assasination (targets an enemy commander)
- artillery (targets enemy province - fires from afar or ghost riders)
- travel/movement
- paratroopers (separate cattegory, because this may allow you to take control of a province)
- summon
- global enchantment
- local,(beneficial) enchantment (Domes, Watcher, Three Red Seconds)
- other
----
battle:
- selfbuffs
- army buffs
- weakening spells (False Fetters, Numbness, Slime...)
- offensive (various damage dealers)
- sniper spells (single target offensive spells)
- symmetric (Darkness, Storm, Rain of Blood, Heat from Hell, Acid Rain)
- reinforcements (Raise Skeleton, Mists of Deception, Howl)
