Pet that hurts its owner (on purpose)

[sweet nymph]

So, I have this wacky, off-the-rails pet for advanced Witches on my server. It's a Voodoo Doll.

It's got a bunch of mechanics, but one mechanic I particularly wanted is for this pet to be able to hurt it's owner in certain cases. Obviously direct - damage won't work, and I'm fairly sure that - sudoskill for self-damage isn't going to work either (though I haven't fully tested this, just a bit).

Does anyone have any clever ideas to **bypass **pets not being able to hurt their owners?

(I could see it spawning an invisible mob to indirectly hurt the owner, but: there's a chance this damaging could be rapid fire. So spawning an extra mob for this purpose seems inefficient.)

Why wouldn't the damage mechanic not work on @PetOwner ? I'm not sure to understand

In general, it seems pets can't hurt their owners.
for example, this on a mob skill absolutely does not work: - damage{a=3} @PetOwner ~onInteract

or this. - damage{a=3} @PetOwner ~onTimer:40

I'm going to make an attempt for my pet pet to spawn an invisible, no-hitbox pet's pet, that will mount the pet and traffic ~onSignal

Okay, I found a way to cheese a solve for this, without all this crazy pet's pet stuff.
Mob: - setparent @NearestPlayer ~onSpawn
And in the mcpet's file, I just tightened the spawn range a bit as a precaution: SpawnRange: 2

Correction: this doesn't seem to work after all. Drat.

that is very weird, I've never seen that before

how about applying a potion effect of instant damage?
