This is a brand new idea that should be EXCLUSIVE for Pirate legends. Basically, it adds a brand new quest type, more mechanics, and more ways to earn rep. Plus brings us more lore.
Let's say we just started out Pirate legend. So, what is there to do? Well, if we take a look t heres teo. The standard chest quest and a "Legendary Journal" quest. So, because we don't know what the second one is like, we pick it.
Once we go to read the map, there's basically 10 pages from the same journal, which leads us to famous members of the same crew. Basically like order of souls, but instead of knowing who or how many, it gives us the exact location they went to. For example, "My newly formed fleet was all a rouse, and was never intended to share the loot. Last time I saw their ship they were heading to Mermaid's Hideaway. After I hurry my chest I will go after them." So we find he never did that and we finish the deed. Of course also taking their skulls. Also there might be other entries like "The last chest I had brought my crew some devastating side effects. Better to leave it under the sands in Smugglers Bay's tunnel entrance." Which would introduce us to new chests.
After we get the rather legendary loot and finish off the crew, we find one last entry. Something along the lines of "My time is running short and I have cursed the seas for long enough. I shall retire to the farthest corner of the sea and become the Devil under the ridge." Which basically gives his location.
Once we find him or hee, he will be one of the first to spawn, but each time we do enough damage, he will summon more and more skeletons. Like let's say... 10 waves at most, and 5 powder keg blows to kill him. (The boss gotta be hard and rememborable) and once we finish his crew and defeat the captain, we find his unique skull, so other legendary skulls are unique. Upon returning the unique skulls to the Legendary Person in the tavern, we will get new gear. Maybe a unique weapon that might look cool, have a cool and unique move to it, And new Gear. Maybe even a new body kit for the ship to change the hill to a unique look.
So. That's one idea on how we could improve Pirate Legend.
