The Bishomen Spear is a somewhat powerful weapon. It only has 30 damage, but has 2 to 5 Element Damage of every element. To get the first piece of the Bishomen Spear you must go through the Caverns Of The Ancients. Find the exit to the southeast slope. You must use Benkei (fat character who is the best with polearm and spear class weapons) to obtain them. You must look for three rocks. Each is located on different parts of the southeast slope. Attack them, but be aware that every time you obtain a part a unique monster will try to defeat you and bring it back to Zanshin. The monster that most commonly appears is a Bach Yori (a member of the Wolf Clan). The last one is always random. Brick can only use this weapon.
When you see a Boss amongst the other guards it has, kill the guards then aim your attacks on the Boss. Almost kill the Boss, leaving a small amount of life. Save the game, then kill him. If he does not drop a unique (blue colored) item, press [Shift] + 5 to reload your saved game, then kill him again. Each Boss does carry a unique item, but only has a 1% or 2% chance to drop it. Keep repeating this process until it happens. It may be irritating, but most of the time the outcome is worth it. This trick is especially useful when in the DarkWarlord's Property (blue line on the map). Once such item that can be obtained this way is an Imperial Harpoon with the following statistics:

Press [Shift] + 6 during game play to quick save. Then, press [Shift] + 5 to quick load. When you do this, your health and Ki will double. This is useful when you are low on health and do not want to wait in the shrine room.
Save the game at any point. Hold [Alt] and press [Tab] to switch to the Windows Desktop. Go into "My Computer/C:/Sierra". Right click the the "Sierra" folder. Then go to "Send To" and "Compressed Folder". You should see a folder appear that looks like a folder with a zipper. Hold [Alt] and press [Tab] to switch back to the game. Throw down the item that you want to duplicate. Save the game again and go back out. Go to your "Compressed Folder" and go into "Characters". Highlight everything in this area then hold [Ctrl] and press C to copy those items. Go back into the actual "Sierra" folder, then go into "Characters". Hold [Ctrl] and press V to paste those files. Switch back to the game. While holding [Shift], press 5 to reload your earlier save. Go into your inventory if it is not already displayed. You should now have the item you threw on the ground back in your inventory. However, the same item is also on the ground.
To see all items, press [Alt].
