Because I did not see this in the new sea thread, request for Mafia to track the drop monster of the Mer-kin lockkey.
And, ideally, set the choice of Into the Outpost (Choice adventure number: 312)
From the Wiki:
(1) If the lockkey dropped from the Mer-kin burglar, the stashbox will be available from one of the choices from Sneaky Intent.
(2) If the lockkey dropped from the Mer-kin raider, the stashbox will be available from one of the choices from Aggressive Intent.
(3) If the lockkey dropped from the Mer-kin healer, the stashbox will be available from one of the choices from Mysterious Intent.
