anyone know the combination? i went every where in the area and no hint and i really want to know whats in those rooms lol
There are 4 switches, each with 2 possible settings: up or down. That makes 2^4 = 16 possible combinations, 8 of which open a vault and 8 of which do nothing.
It's pathetically simple to just count from 1 to 16 in binary and loop through the combinations that way. The game alerts you when you hit a valid combination and even goes so far as to tell you the exact number of the vault that the combination opened.
I think it's mainly potions but one axe is in one of the warehouse doors.
The axe is Gaia's maul, iirc. Those potions include one or more elixers as well, I think.
