Trap Parts[ | ]
Trap Parts are items in Orcs Must Die! Unchained that change how your Traps behave or add passive bonuses to them like lowering cooldown or amplifying damage. You can obtain them from Chests just like Traps or Traits. You can also buy them with Gibs through the Traps Chest at the Premium Shoppe section of the Store, it costs 4000 and contains 2 unique Trap Parts and 1000
Each Trap has a maximum of three part slots. Depending on the type of trap, each of these part slots accepts a specific type of part that modifies the trap's function. There are 10 different types of parts, and several different examples of each. Some of them also interact with Elements.
Killer killboxes require quality traps! Add parts to your traps to customize their behavior.
Trap Parts Types[ | ]
Don't be afraid to experiment when it comes to your trap parts! You can mix and match parts as often as you chose without any cost. Adding a part to a Trap is not permanent, and they are not destroyed when they are removed. You can swap in different parts without penalty until you find the configuration that works best.
