Spell Help....

I have Searing Arrow for a ability but I also want it to add range But I cant find any way to do this.

Add the buff that adds ranged damage (forgot name) If I understood your question.

Try changing the casting range in Object Editor.

Hope this helps.

the game ignores that , and the casting range of searing arrows is always the range of the hero

Hmm, if there was a way to pause the unit when the spell is cast, then change the range and reorder the unit to cast the spell, then it might be possible, other than that i cant think of anyway.
