AC4 Naval battles against all Legendary Ships. Assassin's Creed 4 Black Flag naval gameplay.
AC4 Naval battle against Legendary Ship - El Impoluto. This ship is located in the upper left corner of the map.
I have recorded this video long time ago, but did not post it because I wanted to add commentary. However recently I have too few time when I can speak loud, so keep this video for too long time. Now I decided to post it without commentary otherwise will delay it for one month more... Hope you can understand and forgive me :) I put detailed description below.
Legendary ships are bigger than the Jackdaw, much faster, and with the longer range of all cannons.
My Jackdaw is upgraded to the full level - all Elite weapons and storage. However even in this situation there is no way to win the Legendary ship in direct confrontation. You should have a strategy. The strategy is different for every Legendary battle. You will figure out after several tries and failure.
This is my third attempt of this Legendary Ship - El Impoluto. I was very lucky to win this battle because I did not use the correct strategy. El Impoluto has very strong Ram and Front Cannons. It has 12 chase cannons! (compare to only 4 chase cannons of the Jackdaw). It always attacks directly rushing to you, shooting from its front chase cannons and finally attempts to ram you.
If you are going towards this Legendary ship - try to avoid the collision, deploy fire barrels and use broadside cannons combined with the Svivel until this ship will go more far for the next round. After it will go out of your broadside cannons range - use mortar.
Once El Impoluto is rushing towards you you can try to go away dropping as many fire barrels as you can and using mortar. However this ship is fast enough to chase you down - try to avoid the collision. Use fire barrels heavily when it attacks you.
The best if you can manage to sit on its tail - it is fast - use chain shots to slow it down and combine with mortar or chase cannons trying to trail it as long as you can.
Abstergo Challenge completed - defeat a Legendary ship.
Next legendary battle is in Serranilla - bottom left corner of the map - against La Dama Negra. This ship strength is in it's mortar; weaknesses - slow speed and long reload time of it's broadside cannons. Take advantage of your speed. Ram La Dama Negra when it is possible. Keep behind this ship is very safe. Attack with mortar, broadside cannons and swivel.
Next Legendary ship is HMS Prince. This ship is also not very fast. Broadside cannons, round shot and swivel finish are very effective against HMS Prince.
The last and the most difficult naval battle is against 2 legandary ships - Royal Sovereign and HMS Fearless. Both ships are very fast - much more faster than Jackdaw. Do not attempt to chase them - no use. Instead when they are rushing towards you - try to sail away to reduce approach speed, so you will have a chance to aim mortar 1-2 times. Try to avoid to get between them. HMS Fearless is weaker - attack and sink it first. HMS Fearless is vulnerable to ram attacks. Once you sink HMS Fearless - Royal Sovereign will become more aggressive and will rush to ram Jackdaw. Try to avoid this attack, use fire barrels. Mortar is not very efficient weapon agains Legendary ships - mortar is too slow to aim and will often miss because of the high speed of legendary ships.
Remember to brace under enemy fire to minimize your damage.
The reward of defeating all legendary ships is Charge attack. The charge attack allows you to temporarily SPEED UP the Jackdaw to RAM an enemy ship with more STRENGTH. Hold L1 while looking forward and then DOUBLE TAP X to charge.
