what is the best way to level up my pirate???

I would suggest keeping your weapon levels within a close range of each other.

Ex.) Having your cutlass at level 20 and grenades at level 17 is ok.

I wouldn't want them over the range of four levels. I made the mistake of having grenades level 15 and all of my other weapons at 20+. It's been taking me even longer to level my grenades now than it might have been if I kept them within the range.
