Clock of Opening

• Rarity: Rare
• Type: Wondrous Item
• Attunement: No
• Source: Level Up A5E

This grandfather clock weighs 250 pounds and tolls loudly every hour. Among its internal mechanisms are 12 keyholes of various sizes. Any key can be inserted into a keyhole.

If you are trained in the Arcana or Engineering skill, you can use an action to cause a lock within 500 miles to magically lock or unlock by inserting the lock’s key into the clock and adjusting the clock’s mechanisms. Additionally, so long as the key remains in the clock, you can schedule the lock to lock or unlock at certain hours of the day.
