The last legendary man of war in AC4, I swear that thing flipped 270 DEGREES in the AIR, and crushed my fully upgraded brig, the 2 man of wars one was easy-unarmed hulls, and all you have to do was kill both almost at the same time. The last one whose name I forgot was flipping around like a speed boat, almost immune to my mortars which 1 hit kill frigates, more agile, and faster than you, tries to ram you like a brig, has cannon range that outrages your mortars, can dodge cannon shells and heavy shot which also one hit kills frigates, and 2 hit kills normal man of wars as well as being immune to those. So how do you kill it, you lose your dignity, go to a guide, find a video that says forward cannon it when it tries to rams you, and counter ram it with a 35 percent chance of doing it. Then you hope it jumps in the air so you can Dmg it's weaker lower hull which rarely happens, and if it does the ship has a better chance of air jumpi ram you, or you turn ship's back perpendicular to it's side, and fire barrel praying it won't be able to ram, or broadside you, than you repeat the above. It took me Atleast 10 tires to get it right, and 4 with the information from the video.
