Routine (4 actions) The trap loses 1 action for each disabled ink spout. On each of the trap's actions, a spout pours ink, increasing the depth of the ink in that vat by 2 feet. Creatures standing in the ink are exposed to a dose of poison ink. Once the vat is full of ink, the trap stops using actions, but creatures in the vat might start drowning.

Reset The trap can be reset by refilling the ink storage tanks above the vats.
