Custom spell questions

Is there a way I can make a hero skill increase sight and range. Not permanently, because I want my hero to "reclass" later so altering its sight/range permanently would be bad. I tried making the acquisition range huge and basing the sight bonus off of that little telescope item, but that didn't work out too well.. (It didn't even give me an icon when I clicked on its counterpart in hero abilities).

I have a bloodlust mod that only targets self. But autocast doesn't really work with this spell. Is there a way to make it realize that it can only target you and trigger?

(Would never ever happen but I might as well ask) Is there anyway to make chain lightning target units it has already hit? (not the one its currently hitting, but say you chain a pair of units and the chain bounces between those two until it runs out of leaps) If there was a way..*twitch*

Off topic, how do you make the entire screen tint a color, or the screen except a circular region tint (I cant find it *grumble*)

I don't like to let posts slide down the list with a "0" for responses, so I'll try to help with what little I can.

For your first question, it may be that you did not define your ability in one of the pairs of <race>AbilityFunc.txt and <race>AbilityStrings.txt files. The ability needs this information to display anything about itself, and if you set it to look for it's own description in AbilityData.slk and it doesn't find one, it might not display anything.
