I have run into a few of these puzzle chests....they are very fun and kill me often... I have yet to actually unlock one yet tho...
I now have 120 lp so it gives me a decent hint....
Ran into one the other day.
My lockpicking hint:
In the first slot : Green
Used in unknown slot : Light Blue, Yellow and Red.
There are 5 boxes for colors.
I was able to figure out the following before it started instant killing me.
Box 1 : Green
Box 2 :
Box 3 : Red
Box 4 : Yellow
Box 5 : Light Blue
I was curious on Box 2. With the hints I was giving, would those colors be the only colors used? Or are the other colors(Dark Blue, Purple, Blue, Orange) can be used for box 2?
