How to defeat Praxis in Destiny 2

When playing Destiny 2, Praxis is one of the more difficult villains to defeat.  Finding him is hard enough.  You have to hunt him down.  When you find him, defeating him seems impossible.  In your attempts you may die over and over.  Fortunately, in a video game you get extra lives.  Here is the secret to defeating Praxis.  Use this method and you will have good success and few deaths.

The room in which the battle takes place is rectangular and is wider than it is long.  A porch surrounds 3/4 of the room overlooking an abyss into which if you fall, you die. There are several platforms in the middle and their are all accessible with easy flying leaps.  Some of them are elevated on poles.  MOST IMPORTANT, there are four balconies, two on each side of the room.  These balconies are the secret to winning the level.

When you advance into the room Praxis will descend and immediately loose a wave of killer goons.  They will come at you viciously.  Praxis has the power to freeze you in place using Stasis.  Make one quick attack on Praxis if you want using your Super Power, then then run to either side of the room and make a flying leap up onto any one of the balconies.  When you land, back up into the balcony as far as you can and hide.  The goons cannot get you when you are on a balcony.

From the balcony, you can easily pick off all the goons.  In between each wave of goons, inch forward and take a few shots at Praxis using you heaviest firearm.  He/She is immune most of the time, protected by powerful shields.  Keep trying.  Praxis will summon another wave of goons..... repeat, repeat.  Sooner or later, the shields will go down and you have a few seconds to do some major damage to Praxis.  Continue in this fashion and defeat each wave of goons, shanks, and whatever else comes along.  Always back into the rear of the balcony after shooting at Praxis.  He will follow you around the room and will be out of sight, right below the balcony.

Soon you will run low on ammo.  Rest up, then leap off the balcony and run around the room defeating goons and picking up ammo as you go.  Go quickly to the other side of the room and leap up into a balcony.  Continue shooting goons and blasting Praxis in between waves.  

When Praxis' energy get down to 1/3, one of the stronger goons will drop an important stasis device.... pick it up on one of your runs around the room.  You will now have the power of stasis, the ability to freeze the enemy and your super power will recharge very fast.  Blast Praxis with stasis, it is now your super power. You can do this from a distance and you will see a faint targeting ring to guide your shots.  In between blasts, run to avoid the goons and blast Prixis with your heavy gun.  Continue this procedure until he dies.  You win.  Piece of cake.

If you have slightly above average skill, and you follow this procedure you can defeat Praxis without getting killed yourself.  If you do get killed, start over and try again.  Keep in mind that I am basing this guide on the fact that I play Warlock and had a power of 1205 at the time.

Note:  Instead of running around the room when you are out of ammo, you may be tempted to leap onto a platform, pick up ammo, and then leap on across the room.  This works fine, but if you miss a jump, into the abyss you go.
