The Super Pole is a construct available to the Miner and Engineer classes, which takes 114 blocks to build. It is a large 3x3 pole, 13 blocks high.
Super Poles are occasionally used as 'stilts' to life structures off the ground and get them in the air quickly. However, this makes the structures relatively easy to collapse if the poles are destroyed.
In the Demolition game mode, the Super Pole can be used to effectively re-enforce bases. It's narrow size means that it can fit into spaces that larger prefabs, such as the Super Dome, cannot.
