Non-Hero Ability Leveling

In order to reduce the size of my map, I'm experimenting with adding levels to already-created unit abilities in order to compress them into one ability. This way, when my hero learns the spell that uses the spell, the triggers will update an upgrade to increase the spell's power for that player.

For example, I created a Raise Dead ward. I want the ward to summon increasingly powerful units as its summoner increases in levels, so I made a trigger that sets his upgrade level up as he learns the ability, in order that the ward's ability gains the level and summons more powerful dead.

This fails to do anything, though. Why not? The upgrade applies to the new ability, and all its summons are in place.

why dont u just replace it with a unit in triggers :D

Because there will be differences in how many summons can be summoned, also. The ward has X amount of mana, and as the spell rises in levels, it lowers in mana cost, allowing the ward to summon more.

I could always give the ward more mana with triggers, I guess. But I'm still interesting in non-unit-ability leveling.

If it's a ward then you have to order the ward to cast the ability with triggers.

Untrue. It casts the spell; the spell simply does not gain levels.

Of course, it probably simply casts since Raise Dead is autocast.

Maybe you need to have the ward use the upgrade too I dunno. I was under the impression that this type of unit ability leveling was definitly supposed to work with 1.15

I started using this yesterday and man does it save space in the Object Editor. The caster has to use the upgrade for it to work; so that wouldve been why it wasnt leveling the ability.

Aaaah, okay. Thanks.

The only disadvantage to this method is that skills can't be unlearned properly, as upgrades cannot be decreased. Oh well. Tomes of Retraining are overrated :P

You know you can Set the upgrade to the level you want and easily decrease and increase with trigger, I did it before ...

The whole topic here is about using triggers to upgrade a unit ability; so he already knows that. You cant decrease the level of an upgrade the same way though. There is no way to decrease upgrades as far as I know.

oh shit, sorry I think we was able to change the level but the bugged game don't take the effect. This completely ridiculous, really complexe editor and a stupid restriction for upgrade. We can't use upgrade if you want to use book of retraining. The only way is to use item ability or something like that.
by the way any know if we can set the level of a non-hero ability in game?
