=== Part 3: Trap Corridor ===
# Once past the gates do not rush ahead - there is a pyramid trap. You will also find a lever on the wall right before the entrance to the tunnel with the trap. 
#* Note: Pyramid traps do roughly 400 damage with an aegis active. A pierce protection rare negates all damage.
# In the trap tunnel, there is a wooden door (no lever, it's just a normal door). Midway through the tunnel there is a 4-way (with colored mist) where you will notice a frost ring spell trap that fires every couple of seconds. Once the trap fires, pyramids will shoot out of the same location going in all 4 directions. Note that the pyramids may in rare cases fire simultaneously but more often will fire one at a time following a pattern. First, a pyramid will head toward you (backwards). Then a pyramid will head toward the wooden door (forward). Likewise, pyramids will also shoot off into the other 2 tunnels (to the left, S and right, N). There will be cubicles in the tunnel wall that you can use to make your way forward. 
# Solving this part requires coordinated lever work. Past the wooden door, you will find a lever-activated metal gate (your goal). To open this gate, you must first press the lever at the entrance to the trap tunnel. 
# This will then open a gate to a room with a lever in the tunnel to the right (N) from the 4-way. One person should make their way there to pull this lever when the door opens.
# Doing so opens a door to a lever room in the S tunnel from the 4-way and likewise you should position a person there. The person pushing the lever in the N tunnel will not be able to make it to the S tunnel on time without hitting a pyramid - remember pyramids will also fly down these tunnels.
# Once you pull this lever, the metal gate past the wooden door will open. There is a lever right after it, which you can use to re-open it. Thus, there is no need to block it as long as one person makes it past.
