Removing off/on from an ability?

Is this possible? I know I'd need a new icon for it, but aside from that im not sure what to do.

If you're talking about autocast, I just put a blank space " " into the tooltip off and tooltip off extended, and set the icon to the one without a yellow border. Most people will never realize it's autocast.

should have been more specific...this particular ability is based off the 'Kaboom!' ability, thye might notice an autocast troop explosion....

You cannot change an autocasting spell to be unautocasting.. However depending on your goal we may be able to do something...

Please give the actual spell your trying to do and what you want to happen.

I'm trying to make a non-autocast of the 'Kaboom!' ability used by goblin sappers.

Couldnt you just detect when the order of autocast kaboom is on and set it false?
