AOE ability that gives some buff?

I need an AOE ability (casted) that gives some buff to friendly units.
Anyone knows one?

Drunken Haze can be modded to do that.

Scroll of Protection has an ability that does that by default. Use that.

Big Bad Voodooo?

I already used all scroll and rune area abilities of that type, that is why I asked for casted one.

Drunken Haze is complicated I would use it only if there is no other option, anyone?

Silence.

Replenish Life / Replenish Mana / Roar.

All already used.... damn.

I think I will just go with ForGroup + one unit buff ability.

Soo anyone knows one unit buff casted ability?

Cripple, curse, inner fire, acid bomb, drunken haze, parasite...

Also, do you use both roar abilities? They have different orders; the hero one with orderstring "battleroar" and the other is "roar," both count differently for orders.

All used except acid bomb.
Hmm will try that roar thingy, tnx.

EDIT:
Omg they do have different buffs, great.

Thunder Clap/Slam with 0% slow and modified Targets Allowed? They use separate order strings (thunderclap for Thunder Clap, creepthunderclap for Slam) and the red debuff text can be easily rectified with a colour string :D They're the only two I can find that haven't been suggested :\

Or does it need to be point-targetable?

Those were probably not suggested because they use local terrain modifications.

I already solved my problem but tnx for trying to help.
