wait invisible as in the sense where no one can attack u?

1. Don't know
2. It's probably the new sailing skill that you unlock after you complete the boss battle called "Leadership". It causes the ship to have a white-bluish glow on the deck. (thats not the point of the skill)
3. Those aren't new, there just aren't many of them and they are mostly behind Padres and around that area.

I have seen about three or four Black Harbingers, around fuego near the juggernuts and such..

was it me you saw doing that? lol
2 days ago there was some glitch in my game where i could get fired on and fired on in my ship and my ship was not taking any damage. plus, it lasted the whole day no matter if i exited the game and re-started or just logged on/off. and yeah i was sitting in my sloop off the coast of padres hitting the juggernaut and others.

oh btw I do know the invincibilty ship glitch where no ship will ever fire back at you. downside is you have to redo *the little secret that im not posting on here for fear they will fix it* everytime you port.

1: The ship might have used take cover once, or just dodged some of the cannons. Smart sailing, got that right. :D

2: The white light around the ship is the leadership skill you get after you complete the boss battle. Everytime you use it, the ship glows.

3: Black Harbingers have been around a while, but are only seen southwest of PDF, to outcast, and beyond.

A few days ago there was a glitch on the whole server. If you were on Cruzman server, you could sail and never sink. Needless to say it was fixed the next day.

Thank you for answering a question I had...I saw my first Dreadnaught tonight and wondered if it was new.

I personally have only seen two Harbingers. Lucky I was in a warship with my fav pirate partner or I would have sailed away PDQ! :)

I had that happen to me one day when my ship (a war galleon) was taking no damage. I didn't exploit it all that much because I'm not in the habit of getting in the way of incoming fire. I went about my business and went off line for the night and everything was back to normal the next day.

It doesn't seem to happen as much now but the glow from Leadership can hang around for a while. Also they seem to have changed the graphics so ships get a shimmer before using Full Sail or Ramming Speed (and I think Come About).

I have run into a few Harbingers now and just a word of warning, they use thier forward facing guns unlike the other skeleton ships.
