You are playing Nightmare mode.

While the active location is Underwater , encounter card effects cannot be canceled.

Forced: When the 'when revealed' effect on state 2A resolves, Captain Sahír makes an immediate attack against each player in turn order, instead of only the first player.

Begin with the standard quest deck and encounter deck for The Drowned Ruins scenario.

Remove the following card, in the specified quantities, from the standard encounter deck:

1x Cursed Caverns / Twisting Hollow

1x Undersea Grotto / Dark Abyss

2x Throngs of Unfaithful

2x Soulless Cadaver

2x Drowned Cave

3x Into the Abyss

1x Tangling and Grasping

2x Sea-scorpion

2x Cave Eel

Then, shuffle the encounter card in this Nightmare Deck into the remainder of the standard The Drowned Ruins encounter deck.

Finally, flip this setup card over and placr it next to the quest deck. Its effect remains active throughout the game, which is now ready to being.
