@typicalink500 said in Question about voyage lenghts and values:
I have a question: i know captain voyages are usually shorter, but are captain's vault stashes, ghost ship battles and lost shipments shorter than their regular counterparts?
No, they use the same exact voyages, but repackaged for captain purchase.
Also, you unlock Gold Vault Keys at GH level 45. However, are level 75 vaults better than level 45 ones if they have the same keys?
GH vaults top out at max value when unlocked at 45, there is technically no level 75 voyage.
And is this true for lost shipments and ghost ships as well?
It is true for lost shipments. But it gets complicated for ghost ships. At level 75 you unlock the chance to get a voyage that gives you The Burning Blade as the final boss. This was introduced in February of last year when they removed the Flameheart World Event but needed a way to let people still work on their OOS commendations that required The Burning Blade and wraith balls.
