Unfathomable

Deal loyalty cards when the Awakening condition is met (Waypoint ≥ 6) or during setup unless you're using the Learning Game variant, which delays dealing loyalties until after the first Mythos (see pages 7, 21, 23).

After resolving a skill check, everyone follows the check’s specific pass/fail effects; players still discard down to their hand limits during the normal Discard step, not automatically because of failure (see pages 16–17 for resolution and page 25 for the Discard step).

Advance the Travel track with successful progress and retreat with failures; if the Travel token reaches 12 or higher the Humans win, while retreating to certain thresholds can advance the Ritual/Threat—follow the token rules on movement and win condition (see page 14).

When a traitor reveals, follow the reveal procedure and apply their revealed abilities and restrictions; they remain in the game and may act according to reveal effects, but some reveal consequences (like being unable to escape or gaining treachery actions) are specified at reveal (see pages 23–24).

Monsters have distinct activation rules: Deep Ones activate and attack/move according to the monster activation procedure, Mother Hydra and Father Dagon have special behaviors called out separately, and examples of full activation sequences are provided to clarify order and targeting (see pages 18–20).

When taking damage draw the appropriate damage card(s) and place their tokens as instructed; Structural and Fuel Leak cards each have specific placement and repair rules and may cause ongoing penalties until repaired (see page 19).
