A Nuclear Warhead, once placed, will automatically begin a 10-second countdown.
In order to craft a Nuclear Warhead, you will need the following materials:
Once a Nuclear Warhead explodes, the region in which it detonated will remain radioactive for a duration of time (By default 5-minutes) with a 50-block diameter. This can be seen by thick green particles in the region which will dissipate once the region is no longer toxic.
The only way to defend against a Nuclear Warhead is to diffuse it before it explodes. This is challenging, as it only counts down for 10-seconds.
To diffuse a Nuclear Warhead in the countdown phase, the player must right-click the weapon using a Wrench. This will sacrifice half of the durability of the Wrench but remove the warhead.
