Best single target dummy spell?

As I've been creating several custom spells that are triggered, I'm now wondering: what is the best single target dummy spell.

By best, I mean it:
1) does not have a stun effect
2) all art must be fully adjustable (i.e. no hard-coded special effects)
3) all effects of spell must be fully adjustable to be set to no effect.
4) not autocastable
5) targets a single unit (duh)
6) targets allowed must be fully adjustable (i.e. finger of death is hard-coded for non-ancients)

Many of you will say "channel" is the best, but the problem is that channel will not show missile effects (violating #2).

So what spells are best for this criteria?

How about the Acid Bomb Spell ? u can adjust it to be single target and haves buffs, and many adjustable stuff :D, you also have drunken haze ... in few words many "bomb" like spells can be adjusted to be single target and have buffs and stuff u want :D

Chain Lightning or Healing wave are probably the best mainly because they can either heal or do damage, can hit multiple targets, have both missile art and lightning effects, don't stun, and aren't hardcoded to not be castable on anything.

They don't, however, leave a buff that you can detect.

acid bomb is the best IMO, the only lesser disadvantage is that AI players won't use this spell if it's set to affect only one target, for all the other things, it's 99.9% fantastic.

Seems like these are the best choices

single target dummy buff: acid bomb
single target damage: chain lightning
single target heal: healing wave

thanks for the input.

Chain Lightning's missile art doesn't work. I doubt Healing Wave's does either. Acid Bomb is the choice when you need a missile without stun.

The best way to damage a single target is using the "UnitDamageTarget" function. It's very customizable. However, it'd still be nice to have a spell that inflicted pure damage with no stun.

Channel?

I knew that. I was just testing those less skilled at paying attention to what they read.
