They attack with Firebrand Broadsides and shoot powerful Explosive rounds from the deck cannons. Due to these powerful explosive rounds, it is best to shoot off the ship's sails and sink her from afar. These rounds also make Behemoths one of the deadliest ships afloat, and they should be avoided by weaker ships, especially light ships. They can be found in the Hinterseas, and sometimes in the Uncharted Waters between Rumrunner's Isle and Isla Perdida, some Behemoths are known to hide out around Isla Cangrejos, East of Kingshead, and sometimes at SvS arena.
Originally, the Behemoth was a flagship but was later changed to a normal vessel.
