Important recommendations:
1. If you do the quest solo, it's better to remove the cadence mod and put an extra status like cold or toxin that you don't have on your other weapons.
2. The best stats for a riven are multishot, critical damage, and critical chance. Avoid having a negative damage stat from the Corpus faction.
According to my polarities, the riven must be of Naramon or Madurai polarity. If you have a Vazarin polarity riven, you have to change the Naramon form to a vazarin one and adjust the mods.
3. This orb does not suffer from status effects, so 60/60 mods are not recommended.
