piss people off with a bunch of meaningless numbers
seriously: some form of rune match-up trail
Ex: in the first chamber there is a "map" on the wall that has a trail of glyphs that lead to the door.
the next chamber forks off into 2 directions. each trail has a glyph in the entrance you follow the one that has the same glyph as the "map" had (sorry if it a little vague)
if you choose a wrong path there should be a dead end with a group of monsters waiting for you so its not just a minor inconvenience
PS. Yoshiboy, if your confused with this (i know i wrote it down in like 20 seconds) just PM me for a detailed description.
