Hi !
As i said on the previous guide you can up diretly to 70 by using Power lvl magazine .
Time to up 80
This gonna be hard a little little little bit
Try to find a good party then go to forgotten ( you can find teleporter at dream island )
A voyager would be great for tath job
for better and fast leveling Nana + Poss and ofc x2,5 amp
At lv 75 try to buy x3,5 amp .
Good luck with leveling tath's all .
