Pit (Locking) | Traps
Description
This pit trap is identical to a hidden pit trap, with one key exception: the trap door that covers the pit is spring-‐‑loaded. After a creature falls into the pit, the cover snaps shut to trap its victim inside.
A successful DC 20 Strength check is necessary to pry the cover open. The cover can also be smashed open. A character in the pit can also attempt to disable the spring mechanism from the inside with a DC 15 Dexterity check using thieves’ tools, provided that the mechanism can be reached and the character can see. In some cases, a mechanism (usually hidden behind a secret door nearby) opens the pit.
