[Spell] Spells that cannot target heros but can hit units with resistant skin

[Blake8]

Is it possible to create spells which cannot be used on heroes but can be used on units with resistant skin?

I doubt it is possible using only the object editor. In the trigger editor you can do it though. If the unit is issued to cast it on a hero, you order it to stop or something like that and display an error message.
You could also sacrifice ancient or suicidal classification for it, add them to heroes and set targets allowed to non-ancient/non-suicidal.

Ok, thanks. But if I set the hero to have the suicidal classification what other units will the spell not be able to target besides goblin zappers?

I think goblin zapper is the only unit with this classification. If you still want to use zappers (I think the only thing suicidal does, is that you cannot load them in zeppelins), you could increase their transport size, so it cannot be loaded.
