La Dama Negra | Legendary ships AC IV: Black Flag Guide

The Black Lady with mortar.

This fast ship's basic weapon is a long-range mortar, which has very short reload times. Additionally, both of its broadsides are covered with heavy armor and hosting a lot of cannons. The best tactic therefore, is to attack it from behind. You should fire the chase cannons at its stern. The slowed down ship can be further shot at from the chase cannons, or take a turn and fire heavy cannonballs, reinforced with the swivel gun but, do not let the enemy escape and respond with mortar fire. You can also attempt attacking from the side of the exposed bow but, it is going to be much more difficult, and additionally you might expose yourself to fire.
