[Problem]Frost Nova without Cold Effect

I want to make a frost nova like damage effect so i modified frost nova and changed damage, radious and removed the buff "Slowed" but the problem is that it still slows and adds the frost model to the damaged units... Is there any way to make it work without the cold effect by not using triggers?

Edit: SOLVED, See my last post too

Try replacing the default buff with a dummy one.

Frost effect is hard coded to slow the target, so set duration to 0.01 as well.

I used both of your suggestions and it worked (no buff image, too short duration) but...
Its better to combine a Missile Based (Storm Bolt) ability with an AoE Based (Thunder Clap) Ability so it requires triggers or jass.

Acid Bomb deals AE damage without the fuss of slow. Comes with handy buffs and missile art too! A very customizable ability.
