How do I do this? I want to dispel a certain magic effect, within a certain radius around the player.

I was thinking it would be as easy as just using a script to cast a spell onto the player, which simply explodes the dispel magic effect with an area of (for example) 20.

However... no matter what I do, the "Area" part of the spell is always greyed out. I have no idea why. So how do I make a fire-and-forget AoE spell that I can cast on the player?

Seems pretty simple... but for some reason it just isn't letting me do it.

Screenshot the window where it's greyed out? I think I know why.

Cant get a screenshot now, but it's where you add in magic effects, for the spell window. I.E. where you can change the duration/maginitude of a spell effect you've added. The "Area" box is greyed out, for some odd reaosn.

Any help?

Why not just make a brief duration cloak of selective dispelling?

The simple way to do this is with scripting - area of effect, if target.hasmagiceffect(akEffect), dispelspell(akSpell).

Alternatively, if this magic effect has a keyword, create a new null spell with any one of those keywords, check 'dispel spells with these keywords' on the effect list, and fire that off.
