A 1-foot diameter sphere with four knife-like legs and a single large 'eye'

An Avenger Advi appears as a 1-foot diameter sphere with four knife-like legs and a single large 'eye'. Its sharp legs also allow it to climb vertical surfaces such as walls. The avenger advi uses its sharp legs to slash at opponents. An avenger advi can also fire a beam from its 'eye' at a target up to 50 feet away, and will set fire to any flammable material that is hit. The avenger advi may use this beam at most once per three rounds.
