Executioner

The Executioner is the final boss of the Mission/Map The Pit on higher difficulties.

Strategy
The Executioner is considered one of the less formidable of the bosses, and is far less intimidating than many of the far larger foes you'd face. But don't underestimate him.


 * One of his tactics is to randomly pick a player and chase him/her down. As long as you can out run him he'll be a open target for any turret/teammate you may have but he will eventually catch up to you.


 * One of his attacks is a electrical shock-wave, either get out of the way completely or make use of a well timed dodge roll to avoid the attack.


 * When the ceiling starts to spark he'll call down a single bolt to strike, it can be very hard to predict and hard to dodge.


 * One of his charging attacks leaves behind a trail of electricity, and although it goes without saying avoid that.


 * Finally when his health gets low enough he'll use his chains to bring the walls closer together, you'll want to be in the center of the room or face instant death.

Keep this in mind and this easy boss will just get easier.
