Hi all,
What I'm trying to explain right now is how to guess as quick as possible the right way for Vizjerei via Arcane sanctuary.
First of all, once the first side has been revealed, Vizjerei can be deduced.
1st option (after the first side revealed) : The opposite of this side. Ex.: If it was North East, it would be South West.
2nd option (after the first side revealed) : The adjacent side. Ex.: If it was North East, it would North West.
To be conclude, the 4th way shouldn't never happen if your logic is good and if by chance you have the 4th way, you're just unlucky, but at least you could get good drops via the chests.
