Hello, in the aft part of Zaken's ship there is a door, I was waiting there for some time but it didn't open, is it any schedule for it's opening? Ty very much

12 o'clock midnight GAME TIME(i.e write /time and find out), that is pre gracia epilogue since after zaken is instanced for night time and day time.

So I have to enter at midnight and wait there until the night is passed because Zaken is too powerful during the night, is this corect? And much better to fight during the day time? Not so much time to wait, if I remember well night is 1 hr and day 3 hours normal time.

What chronicle are you playing as there is a big difference in how you get to fight him on different chronicles

gracia epilogue, I managed to enter, that door is open from 12.03 to 12.33 game's time.
There is another door looking the same and heading outside, pretty close to the entrance and reachable by a flooded tunnel, the same schedule here?
Ty for your attention
