Sweet! I didn't know DrPraetorious had released a new version of his database, I will go ahead update my database when I find the time, maybe during the weekend.
I have indeed not done any integration with summon/unit statistics, as you have noticed. That's somebody else's domain
My dream is just to be able to link to a well organized page somewhere else.
One of the things realistically on my todo list is to actually distinguish between national and general spells, and even indicate which nation they belong to. The spell guide does contain this information. But alas this hasn't yet come to pass
