Are you asking how you should trigger it?

So, this must be trigger right? Well, I do not know how to do it, I did not get idea. It is very stupid that this type of ability is very limited

WC3 has a lot of abilities that are hardcoded. This is why I prefer triggering everything.

So, how this can be triggered? I suppose it is easy. I did not do mapping for ages, I am doing something for good old days, but I found current death coil for demons unused, that is why I need brand new ability in similar manner.

Holy Light is extremely easy! Have you worked with triggers before?

Sure I did. I was map mod back then in 2008 remember
Its just that I forgot lot of things. It was ages ago.

Did you manage to get it to work?

Holy Light wouldn't be a good base because you can't heal undead units.
