@incredifan you need to collect four crimson orbs and place them on the pedestals in front of the stone door. There's one in the background of many of the fight scenes in the desert if you don't what they look like (just red spheres that you press space on to collect). You need to use the levers in the lower southwest corner to find them all - using the markings on the walls as a guide(O=right |=left -=doesn't matter). There is one orb just north of the levers(through a maze of stone doors), through the stone doors on each side of the big stone door you can find one orb in each area, the last orb can be found without using any levers and is found to the east of the big stone door and north of the three npc's that give you quests.
For those stuck on the Cosmic Monolith: Thunder weapons and the Pope outfit are your friends! The ninja cloak for Matt or Lance is also nice. Of course, healing spells like Regen, Revive, and Medipack are also a must.
No, tehfatkid is right - sometimes Kage's spells say they do damage with a number above the enemies head, but then do not actually take away hp from the enemy. Usually the spells do register the damage though. The main place I noticed it was against the leader thing - I can't remember what they are called( the squid like things).
Mine works fine for the most part, the only problem I'm having is that it doesn't reset to 0 until it goes past both backgrounds(then the second pic of the background disappears). I have the code set to _x<-2110 and _x=0.
