Passive Requiring Mana

Is there a passive skill which requires mana to take effect? I want to make a passive skill which regenerates X hit points every second, but constantly drains Y mana each second. The skill should stop regenerating hp if the mana of the unit/building goes below Y. Is this possible?

Of course, trigger it.

Assuming it should stop when the unit is out of mana you could possibly add a negative Immolation with Targets Allowed set to Self.

However it'd require some triggering to make it passive anyway..

The idea behind this question was to know if there was a way to make it without using triggers...

And my answer implies that there is not. I guess you could add brilliance aura to the unit with a negative value and then add life regeneration to the unit, but in order to get it to end when under Y life you'd need triggers anyways. It'd be much cleaner to just trigger the entire thing, including the mana degeneration.

There is one way I could do it, but it'll be a bit a crappy method, involving a dummy unit cast a spell everytime to detect a passing second (and detecting that spell so as to create a loop), but I'm guessing there has to be a much more efficient method to do this, one which I'm hoping does not involve JASS.

Doing it with even GUI instead of that absurd dummy caster thing you just mentioned would even be a huge improvement.

Easy with GUI

This is a bit outside the box, but I feel obliged to mention that I don't think most people will want a skill that drains mana that they don't have any control over. Most people find the Destroyer's mana pretty annoying, for example. The active skills are active for a reason.

That said, I understand you're not soliciting opinions of your idea, but it might be worth taking another look at.

I fully agree. A negative Immolation with targets set to self, would be the best solution in my oppinion.

Dragoon, the reason why I didn't do it this way is because every change in life/mana are going to be synvhronised, and, well, it's not really a bad thing, but it sorts of makes it too uniform, and life regeneration for 10 units are not uniform, as far as I know, because they didn't come into play at 1 sec, 2 secs, 3 secs into gameplay, it more like 1 sec, 2.3secs, 4.5secs, etc (if you see what I mean). If I dnt find any alternate solution, I'll go with what you posted.

Also, Panto and Hans, I see what you mean, but the purpose of this spell is not conventional, as you may imagine :)

How many units in the game would have the ability at once? Because if it's lowish, you could just run 1 timer per unit.

It for buildings, so I guess it could work in that way, but still, aren't there any alternate solutions?

Permanent Immolation have proper effect, but it wont shutdown when mana ends.

Okay, let's recap then, what do you excactly need? Be as detailed as possible please
