The Lord of the Rings: The Card Game – Khazad-dûm

An "Action:" on an encounter card in play can be triggered by any player, following the normal restrictions on triggering abilities (page 1).

The last player is the player sitting directly to the right of the first player; in a solo game that single player counts as both first and last (page 1).

"Immune to ranged damage" means characters participating in an attack via the ranged keyword cannot deal damage to that enemy; however, a ranged character that attacks by some other means (not using the ranged keyword) can deal damage and still contribute its attack value (page 1).

You remove First Hall and Bridge of Khazad‑dûm from the encounter deck and set them aside out of play; they are not in the game until East‑gate is explored, which then adds First Hall (and subsequently Bridge of Khazad‑dûm) to the staging area (page 2).

The first player attaches Cave Torch to any hero and that hero bears it for the rest of the game; if Cave Torch would leave play (including if its hero leaves play) it is removed from the game and set aside, not placed in the discard pile (page 2).

At the end of the combat phase players may optionally bypass the current quest: this removes all progress on it and moves it to the bottom of the quest deck with side 2B face‑down; bypassing is optional and players may instead remain on the quest (page 3).
