Buoy

Overview
The Buoy is a Naval defense unit that is released in the 4.5 Patch and can be built at the Dry Dock. Comparable to a naval Portable Wall, it does not boast the above-average health or armor of the Portable Wall, it more than makes up for the average hitpoints with above-average resistances and the standard immunity to all status effects. It is a very viable blocking unit, and can absorb more hits than even the Battleship Mammoth-Class. They can be placed as decoys to absorb damage instead of having damage-dealers soak it up, and as a shield for shells. It is a good investment, and will serve commanders well.
