Dungeon Keys

Basic Information

Every dungeon has rooms with a locked door or a locked treasure chest. A Dungeon Key is usually needed to open these locked doors/chest.
All keys are usable only on the floor they are obtained on and are automatically dropped from a player's inventory should they try to leave the current floor while in possession of one.
Keys dropped by monsters can be picked up by anyone in the dungeon, regardless of who defeated the monster.

A key that opens a locked door in the dungeon.

Comes in Orange, Green, Blue, Dark Blue, and rarely Teal or Yellow.
- Color depends on the amount of doors in the way before the next key.
Found in every dungeon.
Dropped by a random monster in the last wave of a sealed room or found in a chest in the corner of a pre-spawned rooms.
- Very rarely, no monsters may spawn or one or multiple waves may be missing and a key will drop within the room. This is a bug caused by lag.
- Using Taming Wild Animals or Control of Darkness on a monster that possesses the key will cause the key to forcibly drop from the monster.

A key that opens the chest inside the Treasure Chamber

This key is always Yellow, within the exception of the ones found in The Other Alchemists.
Only appears in certain dungeons.
Only drops from enemies in switch rooms. There is at least one key from every switch that spawns enemies.
- That being said, most floors with a treasure chamber will only have three switch rooms, to accommodate all nine chests.
- Opening the door in a switch room will prevent the player from obtaining more keys provided there are any unhit switches.
Also dropped by Leprechauns in The Other Alchemists and used to open the chests in a special room that requires a Mini Potions to access and is guarded by a Giant Leprechaun.
