Nami's staff

[Blackangel]

with that weather staff, she is very powerful. why do you think usopp gave her the staff? he could have kept it for himself.
without usopp nami wouldn't have any powers

 

[Kaname]

I agree but usopp might not be able to control the weather magic.
He is more used to his plants and if a fights breaks out, nami can take down usopp, without breaking a sweat.

Because everyone in the crew needs to be able to hold their own. It also shows goodwill and make sure that Nami isn't a damsel of the crew.

she is stronger than chooper, usopp because of the staff.
she shouldn't have a power like that.
