In the Temple of Eothas there are 3 bells that you have to ring to (presumably) open the door to the next level.
I’ve found one clue, that the large bell is to be rang second, where can I find the other clues (or what is the actual order).
The correct order is
Right, Middle, Left, Right
Alternately, you can find a key in the same room where you found the clue that allows you to bypass the whole thing.
