ok

that makes it a lot easier. All you have to do is open up the object manager, and click the ability tab. (in world edit of course) Anyway, then find the stormbolt ability, and click on any field once in the right panel. Press ctrl+f and type in range. It should bring you to the cast range field, where you should modify the range. (it is 600 i think) To make it melee, I'd say give it a range of 100. (0 might work, but 100 usually works better) I know that sounds wierd, but that's what you want.
