What buff cannot be dispelled?

I only want castables like inner fire, soulburn, etc.. No auras please.

So, does anyone know which buff cannot be dispelled? Or can even be casted on a magic immune unit.

And the doom spell wont work, because i dont want the hero to be silenced.

Doom.

Thx, but not windwalk.

What i want is like a buff that you can cast on a targeted enemy unit.
However, the buff cannot be dispelled or removed by invulnebility, it can only fade off by itself after 2s.

Doom.

And the doom spell wont work, because i dont want the hero to be silenced.

Web and Ensnare as far as i know cannot be dispelled, however I don't think they can be made not to stop the target.

Another question:

What buff can be casted on a magic immune unit?
Please exclude: ensnare, web, doom, silence, stun, etc..

Aside from the obvious ones, I believe only Channel.
With Data - Options set to "Universal Spell".

Actually, Acid Bomb is in my experience by far the best way to apply a non-dispellable buff. Unlike the other ones, you can turn off all the options for damage, attack/move rate etc., so that it has no side effects.

Regarding the magic immune buff: do you care if it's castable on invulnerables? If not, you can just set Invulnerable and Vulnerable targets. If you don't want it castable on invulnerable units, you could trigger it by setting the Inv/V targets, then preventing the cast if it's invulnerable rather than just magic immune.

One possible hack: Try changing the ability to a Hero ability, then set the Required Level to 6 or above. Ultimates bypass magic immunity. Then change it back to a unit ability. Not sure if it'll stick, but it's work a shot.

EDIT: Just tested it. It works!
