Ok I guess a trigger is needed. Here is the tooltip of the ability I'm trying to create, what would you recommend? It is based off of statis trap, and the statis trap unit it summons has the ghost ability removed (so it doesnt turn invisible), the bundled up web model, divine armor, and targeting priority set high.

It says it "ensnares" units, however I don't care if the units are stunned instead, since it's based off of statis trap, but I do want a "webbed" or "ensnared" graphic to be on all the units in the area of effect.
