Iron Fences can be stacked on top of one another, and if a player approaches the resulting pole while holding the Crouch button, he will quickly slide down the pole, much faster than down a ladder, but still not fast enough to receive fall damage upon touching the ground.
The player is unable to slide down the pole under any tested conditions.
Magnetized iron fence.
- W/o boots.
- W/ all metal boots. (Bronze|Iron|Gold|Static|Nano|Quantum)
- From above and below Magnetizer.
It would seem that the Iron Fences need to be unpowered to slide down them. No boots are required to slide down them.
