Spelljammer: Pirates of Realmspace/Bloodthirsty killer

In order to save the Realmspace, you have to lower yourself to the level of pirates, slavers and invaders and mercilessly kill some of them.

Get equipped
Travel to the six ports and purchase the best equipment for each one of your officers. Magic equipment is more effective and it is labeled with "+1", "+2", "+3", etcetera.

Get a better ship
Visit the pubs and accept any job that requires to destroy or defeat an enemy ship. Look for that ship, board it and conquer it.

After each battle, you can heal the crew at a temple; note that this service is missing in Clive's Den and that the healer in Mingabwe has limited skills. You can recruit more crew members at any pub.

The three shipyards allow to buy five ships altogether, but such ships are ranked less than the galleon you started the game with (lower prices). Also note that the names of "Dragonfly" and "Greek warship" are swapped in the shipyard menus.

🇨🇴 🇨🇴 Ships that can only be conquered: 🇨🇴
 * Shou Lung trader
 * Hammership
 * Man-o-war (usually Elven)
 * Nautiloid (usually Illithid)
 * Deathspider (always Neogi)

Enhance your final ship
Go to a port with a shipyard and repair your ship (Umberguard is cheaper, Waterdeep is more expensive, Hisssta allows to buy weapons only). Then, upgrade it to its maximum and buy the strongest weapons.

With a fully-equipped crew and a fully-armed ship, you are now ready to deal with the main quest of the game.
