Animated Grandfather Clock

Antimagic Susceptibility. The clock is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the clock must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute.

False Appearance. While the clock remains motionless, it is indistinguishable from a normal clock.

Time Manipulation. The clock has advantage on any saving throws made to resist magical effects that would alter its movement speed or number of actions it can take. 

Multiattack. The clock makes two attacks: one with its bite and one with its pseudopod.

Bite. Melee Weapon Attack: +5 to hit, reach 5ft., one target, Hit 6 (1d8+2) piercing damage.

Pseudopod. Melee Weapon Attack: +5 to hit, reach 10ft., one target, Hit 5 (1d6+2) bludgeoning damage. The creature must make a DC 13 Strength saving throw, or be pulled 5ft towards the clock.

Ghastly Toll (Recharge 6). The clock sounds off an ominous, ear splitting toll. Each creature in a 40ft radius must make a DC 13 Wisdom saving throw, taking 8 (2d8) psychic damage on a failed save or half as much on a success. Creatures that are deafened or in the area of effect of silence are unaffected.
