Mangar's Tower  

Spoilers, Level 5

The (unavoidable) magic square at 1n/20e will possess one of your characters. 
The Pool will teleport you to 6n/10e (hurts though). 
The magic door at 15n/10e requires that you have all three silver objects (square, circle, triangle) in your party's inventory. 
The magic mouth at 21n/10e will give you a Spectre Snare if that is what you answer. 

1 Death to those who attack the mighty one! 
2 What can bind the mightiest foes? 
P Pool 
M Mangar
