I really like the fireball spell.  Did you know if you summon 2 firebals at the exact same spot you can make their path ark?(would be great for shooting over walls)  The main reason I like this is because it has inspired me to try something like this myself.  I will make shure to give you credit if I use the fireball concept (I may use a different meathod of spell use).  I cant get the escape spell to work.
