OK, its a good thing you have the Overlord Item because its a very rare drop item. This
item grants you entry to a special area in the game at the beginning of Act 5. Start in
Rhodes and go onto the beach and follow it east, then start moving north towards the
rebirth fountain. Click on this fountain in case your killed (keeps you closer to the area
and you cannot use portal to leave and come back from inside this area). Now from the
fountain move east but stay close to the top of the map, you will see a small gate (its
only about 50 game feet from the fountain). Make sure you have Warden Key also. Click on
it and it opens. Try this without Overlord Item and you can't grant access. Follow the
trail into the cave. Skip the first demon flying because he never dies. Go down steps and
face the turtle boss (has a name like Jake or Chris, these are all developers/designers
names - easter egg area basically). Kill turtle, go through door, kill large Fury boss,
follow around the path (notice as your running there are models of sites in game in
background) and go up steps to face Beastman. Go through door and down steps. Be sure you
have HIGH Fire Resistance on your character. Start by taking out little fire robot (do not
open any doors yet). Now start with first door on left. Kill Red Demon and Large Moose
looking guy (he shoots darts at you in spread formation so you might want high pierce
damage also). Now move to front right gate and kill Plant, Dragon. Now come back to first
right door and DO NOT KILL LITTLE RAM (when he dies he becomes a flaming skeleton and
throws fire and piercing at you together with Storm Surge). So kill the little flame
demons, the Skeleton and dark warrior then the little ram. Once your done with these guys
goto end of walkway and a Large Boss comes out of ground. Kill him and you can open the
Majestic Chest. Opening this chest can give you a boat load of good things
(charms/shards,yellow, blue and purple items)

Hope that helps you out, would say to be built up with your spell tree before entering
area. Good luck and happy hunting.
