Safecracking Mechanics
Opening Chests with The Sand Seer's Advice
Overview
With some help from Gremix, the local blacksmithtype, I've managed to get this vault opened and examined the mechanism.
The basics are very simple: each vault can be unlocked by entering a combination of 4 symbols in order. If you make 12 wrong guesses, though, the vault becomes jammed.
Each time you guess, you can see how many symbols in your guess are correct, and further how many symbols are in the answer but are not in the right order. An example notation is '1,2', which would mean 1 of the symbols in your guess is correct, and 2 more of the symbols are part of the answer, but are in the wrong spot.
From these clues it's possible to figure out the answer... but given how many symbols there are, 12 guesses is hardly enough! That's what led me to my biggest discovery...
Rune Symbols
There are 12 symbol buttons on the vault lock, but only six of them are actually connected to the mechanism! The other six symbols can't possibly be part of the solution and are just decoys. So the first task is figuring out which six symbols could be part of the solution.
Fortunately, minotaurs' love of puzzles means that the answer is hidden right in the war cache: there are six rune pictures hidden on the walls of each cache. If you find all six, you've narrowed down the solution tremendously. This is imperative!
For this practice vault, I've connected the top six symbols. The bottom six symbols are never used.
Solving Technique
I haven't had time to figure out a complete solution to unlocking these vaults, but here's my system so far:
1. Figure out the six symbols which could possibly be part of the answer by searching the vault for six corresponding images. (On my practice vault, it's the top row of six symbols).
2. Use your first guesses to figure out which of those six symbols are actually part of the solution. For instance, if the possible runes were A,B,C,D,E, and F, my first guess would be 'AABB' then 'CCDD' and 'EEFF.' These three guesses will give me many pieces of information. After that I just make educated guesses.
3. Carry some lockpicks! The mechanism will jam after 12 tries, but a lockpick can reset it. Unfortunately that will also change the combination, but the new combination will still be comprised of only the six symbols you already found.
4. Practice! I've set up this vault to let me practice my lockbreaking skill. Pity I don't have time to actually get much practicing in...
Player Solving Technique

You don't need any hints when using this guessing/logic technique.
1. Check combinations of 2 symbols until you have found 4 hits or checked all symbols. Use an AABB pattern. If you found the hints in the dungeon, you only have to check those 6 symbols instead of 12. Tries 16 in the image.
1a. If after 6 tries you did not find 4 hits, one of the tries that shows 2 hits could be 3 or 4 hits. You will have to test that separately.
2. Now you have up to 6 symbols that could be part of the solution, tries 2, 4 and 6 in the image. Eliminate those using one of the symbols that does not match.
2a. Try 7 uses one symbol from try 1 which is no match and one symbol from try 2 which could be a match. Try 7 is no match so you know that the other symbol from try 2 is a match!
2b. Repeat this for the symbol from try 6 (in try 8, no match so the other symbol from try 6 is a match) and other symbols.
3. Use logic: you now know the C symbol from try 2 is correct and in slot 1 or 2, also the hourglass symbol from try 6 is correct in slot 1 or 2. That means one of the runes in slot 3 or 4 is already correct and the other will be from try 4 but slot 1 or 2.
3a. Put all the symbols in place, both of those in slots 1, 2 and 3, 4. Try 9 in the image.
3b. It was not correct, the result is (2, 2) so we have to switch 1, 2 or 3, 4 but not between those groups. Try 10 in the image.
3c. Try 10 was not correct but (0, 4) means you can switch 1, 2 and 3, 4 and be finished. Final solution at the top, ready to open the vault.
