The door is secured by a heavy internal iron lock. |
Mechanical Trap |
The lock becomes magnetic if opening it fails.
A DC 14 Intelligence (Investigation) check reveals that the lock is slightly magnetic. The lock requires a DC 14 Dexterity check with thieves’ tools to open. If it fails, a click is heard and the lock becomes magnetic. Any tools being used get stuck in the lock. Pulling them out requires a DC 14 Dexterity check. If it fails, the tool breaks. Disarming the magnets requires a DC 16 Dexterity check with thieves’ tools. |
