Poison Needle
~~~~~~~~~~~~~

*Mechanical trap*

A poisoned needle is hidden within a treasure chest's lock, or in
something else that a creature might open. Opening the chest without the
proper key causes the needle to spring out, delivering a dose of poison.

When the trap is triggered, the needle extends 3 inches straight out
from the lock. A creature within range takes 1 piercing damage and 11
(2d10) poison damage, and must succeed on a DC 15 Constitution saving
throw or be :ref:`poisoned` for 1 hour.

A successful DC 20 :ref:`Intelligence (Investigation) <investigation>` check allows a character
to deduce the trap's presence from alterations made to the lock to
accommodate the needle. A successful DC 15 Dexterity check using
thieves' tools disarms the trap, removing the needle from the lock.
Unsuccessfully attempting to pick the lock triggers the trap.
