Activating/disabling abilites

[Drain Pipe]

I'm working on my hero map still and i wanted to make a really good trigger that activated a pssive aura on my hero when she was near water and otherwise kept it disabled.

I want to keep the ability but disable it (like skills that require a certain condition to be activated). I want mine to look like that disabled until she's on water i which case it activates.

I've come up with a way using a dummy unit with the condition for the name, and making that unit the requirement for the spell and by triggers adding when she's on water, and removing the 1 unit when she isn't.
And also making sure there's only 1 unit so the spell does disable.

The problem is that i've heared that dummy units are stupid and useless, so i just want to know if there's a better way.
Now that 1.18 is out, i suppose there could be.

If you mean making icons invisible... That is simple. Add all the passive abilities to a spellbook and then disable it. You will realise that the passive abilities work.

But making dummy units useless? LOL... April's Fool. Dummy units are the key to spellmaking.

I suppose that would work.
