Trigger A creature that isn't a spider walks into the web

Effect The web wraps around the triggering creature's body, clinging to its limbs. The triggering creature must succeed at a DC 20 Reflex save or take a –10-foot circumstance penalty to all its Speeds until it Escapes the web. On a critical failure, the webbing also clings to the creature's face, making it Sickened 1, and it can't attempt to reduce this condition until it Escapes the web.
