I don't do them because I am hardcore though. Some are really good for farming glimmer and bounties.... ie the will of SCROTA and the undying mind. Some are also good for trying to get a weapon.... like the will of SCROTA or if you were trying to get the hopscotch some people said the shadow queef was a good strike to run. Anyway, I don't want to lose my place so I will say more than 100 but less than a 1,000.
