I actually made it work, when I cast my fire spell on the ground, it would ignite a la Flame Wall spell, but I made some change I cant remember and it hasnt worked since.

I'm pretty much trying to make my custom spell (it has the effect of a fire ball) light the ground on fire and cause damage... I created the same fire effect as flame wall, and added it to the effects of my custom spell right below the fireball effect... but I can only get my fireball effect to work. I don't get what happened.
