Wich Spells can my nation cast?
 

I used an earlier posted Excel file (I don´t know who posted it) and added a filter to see if your nation can cast it.
-Go to "Raw Data"
-On top you´ll see Research, and the magic paths
enter the number you desire in top of each, (eg. up Fire put 0 if your nation has not fire and 4 on top of earth if your most powerful earth mage can cast earth 4 spells)
-On the B column filter 1 to see what you can cast or 2 what you cannot
(Research number left of the paths is to limit high level spells so you see early spells and filter out more research-intensive spells)
