If you are considering moving your family to another Guild,
then carefully consider the day of the week you intend to move.
If you transfer to a new Guild on Monday,
you will have to watch your guild members fight the Bosses in Slunterfallen Castle for a whole week
without being able to help them.
Additionally, for the entire week, you will not receive any of the rewards that developers at Pearl Abyss Ltd
have prepared for you for defeating bosses at Slumberfallen Castle.
Which day is optimal for moving your family
to your dream place?
Personally, I think the right day is Saturday,
if you decide to transfer and leave your original guild, there will be a one-day waiting period,
after which you should become a member of the new guild on Sunday.
On Monday, you can participate in all the battles at Slumberfallen Castle,
and all the loot will be available to you that your new Guild wins at the castle.
Good Luck
