Thorn Exotic Bounty

I have the Thorn Hand Cannon bounty almost completed, but there is a Summoning Pits Very Hard you have to complete. This is very like the Strike but a whole bunch more Thralls and Hive in this one. Tried by my self but man there is no way I could complete it, you get consumed by thrall right when you enter the first chamber. Killed most of them, but by the time you get in the center of the room there is a few too many of them plus the lovely Knights Ultra and a few too many Wizards Ultra. This bounty was a three bounty process, the first one was being able to use just void damage in any crucible up to 500 points worth. Next is the completion of a few items you have to get to get to the next steps, see the stranger Etc. You then get this bounty to complete the Summoning pits on Very Hard, they even put another icon to use for this mission. Anyways some day I will have the thorn Hand cannon and anyone that can help would be greatly appreciated. The bummer thing is, my MIC is broken and cant replace it until Next month so its really hard to find anyone that will play without it.
