First of all thanks to "sosalucioleonel" who made this posible with his help.
1 - Now lets begin with the program you need: Notepad++ (https://notepad-plus-plus.org/download/v7.3.3.html)
2 - You need it to modify 2 files on your client: "prop0.pak" and "prop255.pak" do a copy to be safe (Dragon Ball Online \ pack \ prop0.pak).
3 - Open it and look for the search tool, click on replace tab.
4 - Chose your weapon code from this list (ex: I used w_wnd for wand, since I am turtle):
w_axe
w_clb
w_clw
w_dru
w_fan
w_gem
w_gun
w_ins
w_msk
w_scr
w_stf
w_stk
w_swd
w_wnd
5 - On the search box put your weapon code(ex: w_wnd), on the replace box put always "w_www".
6 - Click on Replace all (128 subjects should be changed).
7 - Do it with both files, save it and have fun. 
BONUS: If you dont want to see your gloves and weapon at the same time, install "Czarpos invisible gloves mod" before you edit your files (Czarpos' Mods Thread)
