okay do all of survival trail every day it gives much-needed coins and cult ruins. Upgrade group skills to max all the time. don't lvl gear past lvl 60 unless u have alot of extra coins like 5 to 10mil. as once u get 65+ most of your coins should be on eight inner gates. do all daily and weekly missions. upgrade star lvls of ninja u plan to use for a long time.do all u can do with events for free. as in this weeks event the spending ingots one were u can get free points too get cave keys. do as much ninja exam as u can do and so on tis also. convoy plunder just do everything and in so u get more power.
