Do ninja exam as much as u can and upgrade your group skill, spend your coupons carefully

save your coupons to get better ninjas in events

I have personally never bought a Ninja outside of the lucky board. With lucky board, you get so many rewards, which can boost your power to 500-1500 BP or even more depending on your current BP. Hence, spend coupon wisely don't waste them. Also, have a plan. For instance, some people just buy Ninja beacuse they think its OP and have no idea how to building a team around it.
In short as others have said, save your coupons for an event(more like hoard pretend like they dont even exist). Use them on events where u can get power as well as a good ninja.

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.
