Destiny Eris Morn Bounty RITUAL OF THE FORSAKEN
You need to buy it from Xur for 1 Strange Coin. Eris Morn will then give you quest steps that you need to complete. http://youtu.be/dbW87zUagZ8
Start the special mission on the moon that becomes available once you completed all previous quest steps and fight your way through a short section until you come to a room with a big urn in the middle.
You will have to survive 5 rounds of enemy waves:
Wave 1: Thralls
Wave 2: Acolytes
Wave 3: Knights
Wave 4: Wizards
Wave 5: Malgor the Forsaken and Thogar the Forsaken
HOW TO SURVIVE RITUAL OF THE FORSAKEN
- It’s best to stick with the sword through all waves. You can pick another one up from the middle once it gets destroyed.
- You should keep a good pace because the next wave can start during the current one. But more important is to keep your distance from big groups and attack single enemies or smaller groups. It can happen very quickly that you get overrun.
- Don’t let the Knights get behind you. Line them up in front of you.
