Non-projectile, unit-targeted damaging ability with no side effects

[Pyrogasm]

Seems like someone should have asked this before but I didn't see it in a cursory search. I'm looking for a base ability with the following properties:

1. Unit-targeted and not an AoE effect
2. Deals damage (not a healing spell with negative healing)
3. Does not use a projectile (and is therefore instant once cast)
4. Does not apply any visual effects or buffs (like Shadow Strike's damage text, Frost Nova's blue tint, or a silence effect like Soul Burn/Doom)
5. Is not target restricted (Holy Light can only damage undead units but is otherwise what I want)

Is Finger of Death the only such spell (it explodes units on death but otherwise satisfies these conditions)? Other thoughts:

• Abilities with buffs and effects set to 0.01 duration are not acceptable unless they would literally not be visible or affect the target in any way.
• Acid Bomb and Chain Lightning both fail #3 because they have projectiles.
• Unstable Concoction satisfies all but kills the caster, which could be acceptable in some cases.
• Forked Lightning with targets set to 1 would work if the targeted unit is guaranteed to be the first chosen target every time, but I don't know if it is.
• Life Drain with a very short duration?

You can Chain Lightning, changing the Number of Targets to 1, or you can use a properly set up Channel and deal damage through a simple trigger.

Chain Lightning has a projectile speed and isn't instant (the lightning effect is but there's a projectile that actually does the damage).

Damaging a unit with a trigger isn't what I want, because I want the spell cast to be constrained by normal things like armor type damage reduction, resistant skin, spell shield, etc.. I am fully aware that if I wanted to I could also account for all of these special cases with additional effort as well as using an attack-/damage-type combo that is properly accounted for in armor reduction... but that's not the point of my question here.

Set projectile speed to 0 and remove the visual effects.

Doesn't change anything, Chain Lightning seems to always have a 0.25s delay between "starts the effect" firing and damage being dealt.

• A dummy with proper instant-cast setup doesn't change this.
• Projectile speed at default 1500, maximum 10000, and minimum 0 all have the same delay between the event and when the unit takes damage.
• The same dummy casting Holy Light on the same target does achieve a 0.00 delay between cast and damage so it's 100% the base spell not some setting for the caster.

Acid Bomb damage delay does decrease with projectile speed, but setting it to 0 achieves the same speed/delay as setting it to the maximum 10000 so again it isn't instant.

Alright, why not simply using a Unit-Target Channel ability with triggers for damage dealing then?

Please read what I have already replied the first time you suggested this.

I'm not looking for a workaround. I am asking: is Finger of Death the only such ability that satisfies this, or are there other things I am not considering? It seems weird that there's literally only one spell with no side effects and I'd never thought about it before.

Edit: Never mind, FoD has a side effect: units killed by it explode on death. So only Forked Lightning if it works properly?

Frost nova maybe? Feels similar to holy nova but i dont have my PC to test...

If the buff restriction is only about it not having a visual effect, you could use Unholy Frenzy with an invisible buff and a duration of 0.011 seconds. Then you get exactly one tick with damage equal to the Damage per Second field.

That’s not damage it’s health reduction so it doesn’t grant kill credit, experience, or gold.
