An overcharged Wall of Light becomes unstable, and when it electrocutes something, the arc of electricity can extend to nearby objects/beings, similar to a Stun Mine with the "Chain Lightning" upgrade. So now you have created a "Wall of Chain Lightning", and you can use it to kill guards that are nearby by throwing something at it like a bottle.
