Boss Battle: Retrieve the Black Pearl

[Speedway Master]

Yeah, what i did to beat the boss battle is defeat a light frigate with firebrand, then level up and used the skill point on lightning bolt, used the lightning bolt to pwn the other 3 light frigates, defeat the drawbridges (takes forever), then sink the goliath with ramming. All this takes like an hour alone. If you don't have ramming speed, you're out of luck.
