Finishing Quest:
Did you find this letter on one of the Maiden Cutthroats? Let me have a look. All those accidents were caused by the Riptide Pirates! They raided the cargo ships and made it look like the ships met hurricanes!
- What happened to the people on the ship?
Those pirates are really intolerable. This letter said that "the hostiles have all been thrown into the ocean."
- I will kill them.
Don't get mad. Those pirates and maidens are just minions. The one who planned this is the Pirate Leader. Those Maiden Cutthroats and Riptide Pirates are easy to deal with, but, the real pain in the ass is the Pirate Leader.
- What do you mean?
It is said that the Pirate Leader is wearing a Golden Jade Dress, which makes him invulnerable. If we want to fight him, we have to find a way to weaken his armor. You can ask Kevern about this.
- Right away.(End quest)
