Weapon Unlock: Voodoo Doll

Prerequisites: Notoriety level 5
Benefits: The Voodoo Doll is an incredibly powerful weapon that is able to defeat many high level enemies easily (with the right strategy). The quest might be a little long and difficult, but if you want a powerful weapon at your disposal, then I recommend that you do this quest.
Getting Started: Visit Tia Dalma in Cuba. She says that you need to make your own voodoo doll in order to be able to use it.
First Tasks:
•Recover 4 bundles of straw from Navy ships.
•Recover 2 buckets of pitch from a storage container (barrels).
•Recover 3 bolts of silk from East India Trading Co. ships.
•Recover 2 spools of wire from a storage container (crates).
Let's start with the Navy and EITC ships. You can either join a crew via the 'Find a Crew' icon in the Lookout tab of your Sea Chest, or you can sink them on your own. Low level Navy and EITC ships can be found around Tortuga or Port Royal. Either way, when you're finished plundering the straw and the wire, head over to Port Royal and go into Fort Charles.
All the storage containers we need to search for are in Fort Charles. Continue up the road and proceed into the building. Now look for either barrels or crates that, when approached, have a green ring around them. Be careful because when you search them, any Navy Soldiers near you will attack. These two tasks are best done in a crowded Ocean, such as Abassa so there are other Pirates around to distract them. When you are done with these tasks, return to Tia Dalma. When you talk to her, she says you have made the weapon, but it needs to be given power to truly become a real voodoo doll.
Second Tasks:
•Recover 2 blood from Rock Crabs.
•Recover 3 blood from Giant Scorpions.
•Recover 4 blood from Swamp Alligators.
•Recover 3 blood from Cave Bats.
•Recover 2 blood from Dire Wasps.
Almost all these creatures can be found in Port Royal, so let's head over there. Enter the King's Run now. It is right of Fort Charles and the jail, through the graveyard and into the tree tunnel. Run past the Undeads and kill the Swamp Alligators here. Once you have the 4 blood, continue on until you see a hill. On top of the hill there should be some Dire Wasps. They are pretty high level (levels 6-12) so be prepared with some tonics and maybe a friend or two to help you. Once you have obtained the 2 blood from them, exit the King's Run and return to the Port Royal town. Then enter the Wicked Thicket for the Giant Scorpions and the Cave Bats. The Wicked Thicket is located to the right of Darby Drydock (the shipwright in the big beached ship) and through the tunnel. There should be a couple Cave Bats and many Scorpions here. Retrieve their blood, and exit. Now for the last type of blood; Rock Crabs. The closest place they are is Devil's Anvil, so sail there and dock. Rock Crabs could be a little trouble for you if you are only level 5 or 6, so make sure you purchase some tonics from Gypsys. When you are done with that, go back to Cuba to speak with Tia Dalma. The last thing you need now is bone dust from Undeads:
Third Tasks:
•Recover 3 dust from Undead Gravediggers.
•Recover 2 dust from Undead Bandits.
•Recover 2 dust from Undead Pirates.
•Recover dust from an Undead Witchdoctor.
All of these Undeads can be found in Port Royal, so head over there. The Gravediggers can be found right in the Port Royal town, in the graveyard to the right of Fort Charles and the jail.They should be a cinch to defeat, as they are only levels 1-3. Now go over to Wicked Thicket. There should be Pirates, Bandits, and a Witchdoctor. Kill them (you may need a friend to help you), and when you have retrieved the dust, go back to Cuba to speak to Tia Dalma to get your doll!
Finishing Up:
When you talk to Tia Dalma, she says you have been brave and true, and you have completed the doll. This icon then pops up:
