DROD: The City Beneath/Objects

• Pressure Plates which act like Orbs, but need to be stepped on instead of hit with a sword. Monsters, as well as Beethro, can trigger Pressure Plates. There are three different varieties, based on how and when the effect is triggered.
• Sister Gates, also called the Anti-Doors, close when their specific condition is met.
• Bridges are sections of floor, placed in pits or water, which fall if they have no connection to other solid floor. Thus, if connected to stable floor by trapdoors, they will fall if all connecting trapdoors are removed.
• Platforms are sections of floor placed over pits or water. If Beethro attempts to move off the edge of a Platform into the pit or water, the platform moves (while maintaining its shape) to continue supporting him, provided it is able to without any part of the platform leaving the pit or colliding with another object. Monsters on the platform do not move with it and will be killed if they fall into the pit.
• Hot Tiles kill almost anything that is stationary on them for a turn, including Beethro, but not including tarstuff babies (Tar, Mud, and Gel).
• Water is impassable to Beethro but is the home to certain types of monster.
• Oremites force Beethro, or other sword-bearing monsters such as Guards and the Slayer, to put away their swords while walking on them.
• Speed Potions allow Beethro to take two turns for every one update of the environment.
• Clone Potions allow Beethro to create a second Beethro on any empty square. Pressing the Tab key switches control between Beethro and his clone(s). Inactive clones do not move and cannot be killed by monsters but can be killed by swords, bombs, or other room hazards. Any clone can clear a room, and the room must be restarted if any clone dies.
• Architectural Tokens allow a number of changes to be made to the room when they are touched.
• Mirrors reflect the gazes of Evil Eyes and Aumtlich, and can be pushed around and/or broken by Beethro and his sword.
• Disarm tiles can allow Beethro to toggle whether or not he is holding his sword.
