How do you make a resurect spell for heroes

How do you make a spell that allows you to ressurect heroes (ie. resurrection that works on heroes)? preferably without triggers (using TFT)

Heroes don't leave corpses like normal units do. Therefore, a Resurrect spell will not catch them. Ergo, you need to trigger it. As long as you store whether each hero is dead and where it last died, it shouldn't be too hard.

I think it's possible to make it so heroes do leave a corpse. There's a tag in the object editor that i think is called "death type" which lets you choose whether or not the unit decays and whether or not it can be revived. Set that do "can revive, does/does not decay (second half doesn't matter)", then make a revive-type ability that targets heroes.

It seems i'll have to go with the triggered one. I already tried changing the leaves corpse/ doesn't decay. It doesn't work for heroes, only standard units. thanks anyway.
