If you're a new player or just simply bad at PVP I will give some advice in this thread on how to avoid it. I know people are just gonna say "Oh, you're just upset that your loot got stolen." I do not care. I have plenty of money and currently in a position where I can buy anything I want. This guide is for newer players who do not know much about PVP yet. So here we go:
5: Look out for any reapers on the map.
If a reaper emissary has 5 stars, it will be able to see other emissaries on the map which can be very harmful if you are grinding a certain role. If you see any galleons with a 5 star reaper, that is a big red flag.
4: Distract them with a teammate.
If a ship gets too close to you, have your teammate board their ship and start juking around while throwing fire bombs. While they are distracted, use this time to get as far away as possible from them. The longer your teammate makes the chase last, the better.
3: Only take what you need.
Some quests like the new one will give other players a sign when you are doing it like the big blue tornado. What they are going to want is to make you do all the work and when the tornado disappears they come in and steal the loot. What I did on these ones is that if I saw a ship nearby I would only take the Athena loot or anything that is the most valuable and got out of the place right away.
2: Find the fastest way to speed run a quest.
Many new players might spend too much time on a quest not knowing what to do. In the shroud breaker for example, they might start at the big island and track down the chest. This will give other players more time to find you. Instead, read the whole thing. It will say they dropped the chest off at a island. Just do some problem solving and the island should be obvious. Go straight there to get your quest item so you can move on.
1: Use your own reapers flag to counteract other emissaries.
You need a 5 star reapers flag to see other emissaries on the map. Buy one at the reapers hideout and then do small things to get loot like sea forts. Once you've done enough of them your flag will reach 5 and you can do something bigger like fort of fortune or damned. Have a teammate check back on the map every once in a while to see if any one is coming. Then plan a strategy on them.
