It's not made very clear how exactly trap avoidance works. I initially assumed that it was a percentage chance to evade a trap altogether, but observation seems to indicate that it is basically a number which a "level" of a trap is compared with, and if the trap's "level" is lower, then the trap is evaded. If this is the case, shouldn't there be some indication of the "level" of each trap in the tooltips such that players can actually know if they can pass through a trap or not?
