How's your refinement, magatama, summon runes, equipment & ninja cultivation?

Refinement i have done as much as i can, magatama are quite good, only just got summons so i think its ok for what i have rn and ninja cultivation is max on all my mains

Probably group skills, a lot of people neglect them but they are much better then gear strengthening.

^ Yeah, since your other stuff is good, it's probably your group skills?

Yeah i havent really went near that stuff o:

Don't forget to Awaken as well, refinement's are good, try to get everything up to a certain level of refinement across the board. Dont forget Battle armor, that can give quite a bit of power as well through upgrading and transforming. Magatamas I'd assume you've almost got full sets of level 3's and group skills are a core part of it all.

Well if we determined the problem, stop spending on strengthening and try to ease up on black market, only buy materials and frags for ninjas you really need and focus all your coins into group skills.

As for where to get a lot of coins, full clear survival every day, do rich fields whenever it's up and do 9 tails with a proper team, 9 tails gives so much coins, especially if you are on an emptier server so it lives for more then 5 minutes lol.

Most likely because you focus too much on the plot, and nothing else. Missed daily events, poor resource management, and not staying on top of upgrades. I made a guide about a week ago below that will help out.

Guide

Group skills are definitely the way to go.

Up until around level 55-58, group skills give a bigger "* for your buck", shall we say. Try to get all your skills to level 20, at least; it will be a big help.

Next, your magatama should be at around lvl 3 for all of your ninja, not just your main.

Since you're a lightning main, initiative, and therefore refinement, is key. You should aim for at least lvl 4 refinement on your main and lvl 3 refinement on everything else.

At level 50, you should have already unlocked battle armor. Attempt to make friends around the same level as you and team up to finish Strong Approaching on Easy. There are plenty of guides on the forum, but to sum them up for easy:
Bring two healers and make 1 Sakura.
Make sure you have a combo of around 10. If you use Kabuto and have clones, you can have a little less.
Wait until Shizune heals once before you go ham. After the next round begins, go ham and finish her off before she heals.
Kill Karin and then kill Hanzo.

Good luck!

uhm get good maybe baby? ;)

Battle armor is important.

best thing to do is get refinement up to 90% at least for all ninja in your lineup, and invest in group skills. there's also cultivation, star upgrade, mood and much more

Awakening, cultivation, group skills, equipment strengthening, battle armor, levelling, equipment upgrading, refining, magatamas.

Are you magatamas at level 4 all of them?
Are your equipments strengthened to at least lv45-50?
Are your Equipments refined to at least level 3?
Is your battle armor at least level 6; Rank 1-2?
Are your main group skills (Life, Attack, Defense, Ninjutsu) at level 15-20 at least?
Are your main characters awakened, cultivated to the max?
Are you using your Ninja Tools from the Team Instances? Are they leveled up?

Review these questions and get to work.

Also, below your stamina bar there is a Power Up *on. You c*e that to guide yourself
