Another "Web" like ability?

Is there another ability that makes a good dummy spell base for autocasting spells on enemy units? Basically I want to be able to have 2 spells that are autocastable on the same unit and was going do something similar to how it is done in circle defense. I have web as one possible base, is there another good one that targets almost, or exactly, the same?

You mean a spell that only targets air? Try using slow, faerie fire or curse, and set it's allowed targets to target air only...

Ensnare, but make it's target air, not ground.

I think he's trying to make an autocastable trap ability besides web...

He's trying to find an auto-cast dummy ability. NCCD uses Web for all of it's dummied auto-cast abilities, but it only has one ability on a unit. He wants to have multiple dummiable abilities.

I'd recommend using pretty much any of the negative-buff-based auto-cast spells. As long as you use Darky28's system to stop it from actually firing, it shouldn't matter which ones you use.

I'd just make another Web skill with a different Buff/effect

Having two Web skills on the same unit will cause them both to fire whenever one is activated, as having two of the same skill on a unit has always done.
