Caustic Dart Trap

Three wall-mounted launchers that spit acid-tipped darts across the room in a relentless barrage.

The launching mechanisms can be noticed with Stealth +20 (expert), or DC 30 (expert) to spot the three of them built into the wall. To disable, a creature must make a DC 32 Thievery (master) check to sufficiently jam the tubes to make the trap unable to attack creatures in a single 5-foot square in the room, or a DC 34 Crafting (master) check to alter one of the three launching mechanisms. The trap is immune to critical hits, object immunities, and precision damage.

Dart Barrage [Reaction] (attack)

Each round the trap runs a 3-action routine, using each action for a caustic dart Strike — a ranged attack at +28 dealing 2d4+5 piercing and 4d4+8 acid. The trap loses 1 action for each launching mechanism that is broken or destroyed.
