Midnight Pathlighter

Moving into a dungeon room will cause its room ability to trigger.

A player may only have one dungeon in the command zone at a time.

Unblocked creatures with double strike deal damage twice, which will cause Midnight Pathlighter's last ability to trigger twice.

You can only move forward (well, downward) in a dungeon, never backwards or sideways.

The player venturing into the dungeon chooses which dungeon they will venture into. They may choose a dungeon that they have already completed this game.

To venture into the dungeon, a player moves their venture marker into the next room of the dungeon they are currently in. If they aren't currently in a dungeon, that player instead chooses a dungeon card from outside the game, puts it into the command zone, and moves their venture marker onto the first room.

Once you resolve the last room ability of a dungeon, that dungeon is now completed and is removed from the game.
