Hello there, I just got home. Also, I've done the changes required. I've also changed the spell a little. Now, the unit will only have the Unholy Aura graphics when standing on blight. I hope I didn't miss anything. I'm also expecting more suggestions. Please be kind to tell me my mistakes so I can learn. Thanks for your time.
EDIT: also i need to ask somethings. i've used alot of variable for this spell, if i use arrays will it reduce the file size. also, if i destroy the initialization trigger after initializing will my variables retain its value?.
