Radiant Solar

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.

Dungeons are removed from the game as a state-based action.

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.

If you somehow venture into the dungeon while a room's ability is on the stack, you will continue on in the dungeon. If you're already in the last room, complete that dungeon and start a new one.

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

A token copy of Radiant Solar entering the battlefield will cause its own ability to trigger, but not that of any other Radiant Solars.

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