|Far Harbor quest: Ablutions|
|Speak to Mai|
|Travel to Vim! Pop Factory|
|Locate & take the Regulator|
|Travel back to the Nucleus|
|Install the Regulator|
|Test the Decontamination System|
For this quest, Sister Mai, at The Nucleus, asks the Sole Survivor to acquire a pump regulator to repair the decontamination arches near the entrance. Her directions lead to the Vim! Pop factory which is inhabited by a large number of super mutants and their hounds. The regulator can be found in the Vim factory floor area with the two large mixing vats.
Upon returning to Mai, questioning her about her "repairs" reveals that she is actually attempting to circumvent the decontamination arches' filter systems in order to have them irradiate instead of decontaminate everyone passing through. She then leaves the honor of installing the pump regulator to the Sole Survivor. Reaching the mechanism at the bottom of the submarine dock involves trudging through the dock's heavily irradiated water, so suitable preparation is recommended. With an Intelligence of 7 or higher, the Survivor can opt to reverse Mai's alterations to the system before installing the new regulator, thus making the decontamination arches actually decontaminate as they were meant to do. Return to Mai to claim the unique Radical Conversion radium rifle as just reward regardless of how the quest was resolved.
- If the quest was completed by reversing Sister Mai's alterations she will later thank the Sole Survivor for the work on the decon arches, commenting "... even if it does refuse to spit rads. Saves folk from scouring I guess."
pc ps4 xboxone After completing the quest and choosing to reverse the alterations, there is a chance the decontamination arches will not work, only spraying mist, thus not affect the players Rads in any way. On PC the test of the reversed arches during the quest may work fine at first and clear rads but after returning to The Nucleus later on the arches neither clear rads or give rads.[verified]
