As I said above ghost riders are shocking effective against devils. Heck they are effective against everything except specially made armies or really, really good SC's.

Yes for 5 death gems this spell is seriously overpowering. For the group I play with we've banned this spell... especially after discovering the computer opponents don't use it since most games have at least 3 computer players. In the game we discovered the computer opponents don't use it was Ermor which maxed out his research and owned at least 40 provinces including his capital of 10 death gems per turn... and after 30 plus turns never casted the spell once. Also another side note... Ermor didn't research any blood magic as his research bar flat-lined sooner then it should my guess is others also don't research blood magic.
