Traits

• False Appearance. While motionless, the clock is indistinguishable from a mundane grandfather clock.
• Pendulum Swing. The clock’s pendulum is a deadly weapon. Whenever a creature starts its turn within 5 feet, it must succeed on a DC 15 Dexterity saving throw or take 7 (2d6) bludgeoning damage.
• Temporal Aura. The tick-tock of the Sentient Grandfather Clock warps time around it. Creatures within 20 feet treat difficult terrain as if it were doubled, and their movement speed is reduced by 10 feet.

Actions

• Multiattack. The Sentient Grandfather Clock makes two Slam attacks.
• Slam. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 18 (2d10 + 6) bludgeoning damage.
• Pendulum Smash (Recharge 5–6). The clock swings its pendulum in a wide arc. Each creature within 10 feet must make a DC 16 Strength saving throw. On a failed save, the target takes 27 (6d8) bludgeoning damage and is knocked prone. On a success, it takes half damage and remains standing.
• Chime of Dread (Recharge 6). The clock tolls a deep, resonant chime. Each creature of the clock’s choice within 30 feet must succeed on a DC 15 Wisdom saving throw or be frightened until the end of its next turn.

Legendary Actions (optional, for boss fights)

• The Sentient Grandfather Clock can take 2 legendary actions, choosing from the options below:
• Tick Forward. The clock takes one Slam attack.
• Temporal Pulse (Costs 2 Actions). All creatures within 10 feet must succeed on a DC 15 Constitution saving throw or be stunned until the start of their next turn.

Description
The Sentient Grandfather Clock is a cursed construct, born from dark magic woven into the trappings of domesticity. It stands unmoving until prey draws near, then reveals its true nature — an unholy fusion of time, inevitability, and brutal force. Its pendulum can crush bone, its tolling bell drives terror into the hearts of adventurers, and the slowing aura around it makes escape nearly impossible.
