Whats wrong? It doesn't work.
And allso: How do I do so that it only target undead units? Among the target-list I find dead but that doesn't work eather.

It doesnt work simplay that. . .

that. . .

What is it meant to do?

Without knowing what its meant to do HOW CAN I POSIABLELY KNOW WHATS WRONG.

Please state what the spell is meant to do.

This way is stupid

if- (Level of (Light Aura) for (learning Hero) equal to 1
Then - add (Light Aura) to (learning hero)
else - increase level of (light aura) for (learning hero)

any other way is just needless work.

I made an abillity that would damage undead units when they came near. I based it on permanent immolation, but immolation only change damage when it is restarted. So I tried to make it so that when the hero learned this abillity it would change to the next ability-level. I made several (5) non-hero abilitys that made the same thing, but I needed the triggers to replace them for each lever. The problem is: It doesn't work as I want.
