I am really glad this week's strike missions are both "The Summoning Pits." I just got the thorn hand cannon last week and one of the requirements for the bounty was to complete a special version of the strike mission on level 28 so I know it like it is the back of my hand.

When you spawn, just skip through the initial wave of enemies. Your ghost will say something about going down to find summoning pits. At that point you should reach a sort of cave-like area with a bunch of enemies. You will know you are in the right place if the left-hand side of the area is open.

You want to make sure to kill all the enemies because it is going to make the next part super easy. After you clear it out, just go down a hallway and you will reach the entrance to the place where you have to spawn your ghost to open the door. While your ghost is opening the door, there will be three waves of enemies. During the waves, stay near the entrance you came through.

Sometimes you may get overwhelmed with the Knights. If you do, fall back into the hallway and quickly run up the stairs to reach the previous room. You won't have to worry about enemies behind you in the previous room because you cleared them out. Sometimes the enemies will follow you in the hallway, but they will never come up the stairs. If this happens, just stand back and put shots into them.

Now the second wave will have 1 wizard, but the third wave will have about 3 or 4 wizards. They will only spawn toward the end of the wave. The best way to clear them is to put shots in them, back off into the previous room to recharge, and then shoot the wizards when they pop out from the entrance. Repeat this so you can clear out all the wizards.

After you finished and your ghost opens the door, check to see if there are any drops and pick up whatever ammo is there.

In the next main room, there will be an Ogre blocking the exist. When you enter the room, go right so you can run behind the ogre and the rest of the enemies. Now all you have to do is just run through all the enemies so you can reach the summoning pit.

As the door slowly opens, You will see phogoth chained. Stand in the doorway, shoot his heart until his chains break free. Then quickly rush to the back left side of the pit near the edge. If you position yourself correctly between the rocks along the edge, you can periodically shoot Phogoth and crouch to recharge. The other enemies won't hit you, but Phogoth's laser eye power will hurt you. If you run out of ammo just sit and relax so your ammo refills. I recommend using a scout weapon, sniper, and, a machine gun.

It might take a while, but you should be able to kill him.

I am going to be online on My xbox One in about an hour and a half from posting this if you need help.

Let me know if this helped at all. I put a lot of effort in this.
