I did something ... err ... salty ... last night. Regrettable? Absolutely not.
So I was on a solo sloop and I had just spent the better part of an hour collecting resources for a skeleton ship battle and looking for an alliance to join. I finally noticed a brigantine and a galleon at sanctuary outpost who were allied up and waiting for the Shores Of Plenty battle. It seemed like a perfect crew to ally up with - a Sloop, a Brig, and a Galley. I approached slowly and announced my intentions over the megaphone. When I heard no response I then parked on the opposite side of the island.
One of the other players used the cannon to get close to my ship and asked what I was doing. I then told of my intentions again and he responded by saying "It would be more fun to just kill you." I said "This is Sea of Thieves, not Sea of Murderers." He then started fighting me and when his two buddies arrived I was quickly killed in a 3v1 fight. At respawn all seven members of the brig and galley were on my sloop, spawn killing me. I refused to give up my boat, and after 4-5 spawn kills they sunk my ship. I respawned all the way at Marauder's Arch.
They wasted my past hour of collecting resources just because it was more "fun to kill me." It was personal now (In a light hearted, fun way, of course).
So I set course toward Smuggler's Bay/Sanctuary Outpost in search of my assailants. I stopped at a fort on the way to stock up on gunpowder barrels. Sure enough, they were at Smuggler's Bay battling a skeleton ship. I quickly approached the galleon when I heard them speaking on the megaphone asking me to join the alliance if I really want to. Really? They just sunk all my resources. That ship sailed a long time ago, no pun intended. As I am about to sail within jumping distance of their ship I raise the Jolly Roger flag and hop down from the crows nest with a gun powder barrel. I lit the fuse, dropped it in the galleon's mid deck, and then climbed up to the crow's nest. I then started igniting their gunpowder barrels and dropping them from the crows nest. Within a minute or two the galleon was toast, I got killed, and my ship sank. I wasn't able to exert my revenge on the brigantine, but I was happy enough to teach the galleon a lesson for being jerks at the outpost. Say goodbye to all of your resources.
Should I have not approached two bigger ships at the outpost while I was sailing solo? Probably not. But it's principal. Kill me or sink my ship for no reason other than sadistic pleasure, and I will hunt you until I get my revenge.
