Yup. Will is useful for your heals and barrages; the more will you have, the more you will heal for and the more damage your barrages will do, and the higher the chances you will critical on both. Weapon damage depends on what type of weapon it is. If the weapon is based on Will, you will get the benefits of your increased Will. If the weapon is Strength or Agility based, its damage is dependent on your Pirate's Strength or Agility respectively. Hope this helps.
Your name looks familiar... dead -eye destiny dennis? Don't know if it's just a coincidence or not, but anyway, Cunning Caleb Hawkins, at yer service.
No, sir. Destiny arrives is my discord name. My in-game name is Sean Painer. About four years ago actually, I had two other pirates on a different account; Wicked Aaron Brewster and Cruel Connor Bowman. My Message Boards name back then was Captain Blaze Hunter.
