Drain Life and Channel

Hello, I have about 2 problems that I need help on.

The first is about the ability, life drain, I found out that you can't cast it on your allies. Is there another spell that acts the same as life drain and I can make it have the same lightning effect as life drain but you can cast it on allies and enemies?

The second one is about the Channel ability. I want to know how to make the unit stop casting once the target gets out of a certain range of the channeling unit. I thought that this was what area of effect was but it doesn't work, the target can go to the otherside of the map and the spell never stops. The cast range and the area of effect are all set to 800.

1. Try siphon mana, or life drain for neutral hostile, or devour magic and absorb mana

2. Never knew, go post it in Handy WE tips thread. Don't know how to fix this

I tried mana siphon and it didn't even work on allies, even though the tooltip says it does.

I am not sure I was clear enough. I need a dummy ability that does nothing. When the caster casts it, it should show the drain life lightning effect and make the user channel it. When the target goes out of a certain range of the unit channeling the drain life ability, that ability stops. It also needs to work on both enemies and allies. Is there anything like this?

Siphon Mana didn't work and life drain neutral hostile didn't work.

If it is an dummy ability try Chain Lightning or HJealing Wave.

WAIT. In Advanced settings or something, like, Game Constants found at the top bar of the world editor, there is some on the second half that has something like Gameplay Constants. At one point, there is alot of ability things that tooltips say can happen but the constants are set to false. Some of these are the Siphon Mana and Life Drain sorta abilities that have things like "can cast on allies" or things like that.. I don't know why Blizzard set them to false. There is alot of stuff there you can play around with actually. Hope I helped!
