I had been camping both sea routes over and over and talk my 75 Samurai boyfriend into joining me. Fog and rain were on the ships, but I wasn't even getting the pirate pops. My LS then asked me if I had the pirate quest unlocked. LOL! What pirate quest? So, I go and unlock "Sand Charm," and board the ship for Selbina, and ride a couple more times.
In total, I have been camping these ships for about 4 hours, and then, after boarding the Selbina to Mhaura ship, I get the delayed black screen, like described in other posts. I walk outside on the deck, and its so foggy, I can barely see the water. The music stops abruptly, and next thing I see is the pirate ship coming towards us. Then I see the middle pirate is wearing a vermilion cloak! I look around and see Silverhook, just chillin on the deck. My boyfriend vokes him and we pull him up towards the 2nd deck of the ship to avoid links. My boyfriend starts wailing on him, Seigan, Hasso, Kasha, Gekko etc (all the cool stuff a 75 whm doesn't really understand, but really appreciates). I have to keep taking paralyze off because of the ice spikes. I try a Holy to try to be helpful, but it doesn't do more than 30 damage. His -aga's really hurt, taking both of us to orange. I panic because I don't want to lose to this guy, and Bene for good measure. The samurai beats him, and we get a bone chip and Seawolf Cudgel!!! LOL! 1/1!
.....5 days later, and no such luck with Sea robber....
