The gems outside can only be reached by cheating (hexediting your position). Except for that they are pure decoration... <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />
Concerning the second part of your post I am not sure what happened here. Could it be that you picked up the cursed halberd from the cursed abbey, brought it with you and equipped it in the house of madness?
As far as i know this is the only item that drains stamina.
Besides that if you take a nap in the house of madness you should leave it, so I really don´t know what happened to you.
Kiya, Raze?
