Amend rule 2.7 Monsters to read:

A Monster is a type of game entity; each one has a number of HP and an amount of Damage, which is two integers (a number of Dice and a number of Sides).
An active Encounter exists while at least one Monster exists. The RNG can create a Monster at any time; this either creates a new active Encounter, or adds Monsters to any existing active Encounter. When creating an Encounter, the RNG must detail the Monsters in it in a Story Post with [Encounter] in its title; new Monsters added to an existing Encounter must be detailed in comments to its associated Story Post. In addition, all monsters will be tracked in the GNDT, along with their HP and Dungeon Level. If all Monsters in an Encounter cease to exist, the Encounter stops being an Encounter. Each Encounter has a Dungeon Level, which is any integer, and is set by the RNG. A monster inherits the Dungeon Level of the Encounter in which it exists.
An Encounter can be Ranged or Melee. An encounter starts out ranged but becomes melee if it exists for 24 hours.

In Rule 2.8 Combat, amend:

An @ may not Fight a Monster in an Encounter whose Floor is different than their Dungeon Level.

to read:

An @ may not Fight a Monster in an Encounter whose Dungeon Level is different to their own. An @ may not Fight an @ whose Dungeon Level is different to their own.
