Xbox One.. Kenways Fleet Trade Routes.

I'll Add! I use this heavily! Help away!

I'll happily play assassins creed black flag with you. Need people to join my kenway's fleet?

When setting up the battle, left/right on the left stick selects your first ship, up/down selects the slots to select your second and third ships to join in the battle. The more ships you put in the battle and the stronger they are, the better the chance
of success will be. When the battle is going on you can press Y I believe to use fire barrels if you have them, they're not that useful though. I recommend keeping at least one dock space open in your fleet to salvage newly captured ships for gemstones, doing
the battles you generally run a deficit on gemstones.

I just send my Brig to do most of them. It has a 100% success rate so far. I can imagine it will get harder though so might need to get a Frigate soon. I just salvage the Schooners for gemstones.

If you want to dominate these mini games just go down to the hard areas down south and take a Man O War and add it to your fleet then you can just own the trading routes and will have the cargo space for all the missions. Get 2 or three of these and some
high level Frigates and your set.
