What is a good base AOE spell?

I wish to make a spell that uses the "Area of effect" texture that shows you the range of the area of effect before you cast. I know channel doesn't have this and I don't think channel can be given this functionality.

So what is a good spell to work off of? I tried Death and Decay but it ends up causing some kind of weird effect on the units that I can't get rid of through the object editor.

edit: i found the buff in the object editor causing the effect from the death and decay. But does anyone know other good aoe spells to base off of.
However, Death and decay also kills trees, which is not what i want.

Is that so? I don't have the editor on hand so I can't tell you exactly, but there's an option somewhere to enable a Targetting Image that will show the Area of Effect of the ability.

You can use channel. Data - Options "Visible, Targeting Image". You also need to set the AoE or it wont show anything :p

Silence is also a good one, not channelling + all the effects works.

Well heck, that is exactly what i needed.
