Autonomous Sentry (5e Trap)

Autonomous Sentry

Mechanical Trap

This trap resembles a small ballista in appearance. It consists of a large crossbow integrated into a mechanism that can aim and fire it at will at targets that come within its firing range. No particular checks are required to detect its presence. A creature can disarm it with a successful DC(16) Dexterity check using thieves' tools or tinker's tools.

The autonomous sentry is a construct with statistics listed below. It acts on an initiative score of 10 (losing ties), and on each of its turns uses its action to make a Crossbow Bolt attack against the nearest hostile creature within range that it can see.

The creator or owner of this trap can command the autonomous sentry to instead target a particular creature, object, or area within range with its Crossbow Bolt attack, designate certain creatures to not be targeted, or activate or deactivate the trap altogether.
