Other Events in Weekly Cycles also gives Free Coupons sometimes, but others will require you to participate and the prize for it is a chance of getting a certain amount of coupons. If i forgot to include something, just let me know .. :D

..

Post your available ninjas you have now so that the people here can help you to build a viable team for you to use in Arena :D

There's no limit when it comes to gaining Coupons and Seal Scrolls, collect and save as much as you can until you reach your desired amount of resources .. But if i'm gonna give an exact number, then you may opt to save up to 300 Seal Scrolls and use it when we have Recruitment Feedback (Rebate) to maximize the value of your Seal Scrolls and gain more Seal Scrolls .. You can save up to tens of thousands of coupons too if you want, and spend it when you find a good deal in events or if you buy a certain ninja or item that you really wanted, but you may choose to wait for the event Fukurokumaru Event too where you can get great deals of Rebate ..

Note : When it comes to this 2 words - Coupons and Ninjas, you need to be careful, if you really want a certain ninja, then but his/her fragments in events and do not spend in RNG events where you will take risk of ending getting nothing .. But if your aim and goal is just to get or piece a certain item in that Event's Redemption Store then go and spend some .. It's hard someone to lose all your savings in a RNG event, they all end up regretting and ranting here in forums sometimes ..

I see, so i guess you didn't do what other people did when the servers still on 55 days single server matching at arena .. base on what you've posted, you're lacking in some major *es to make a dish perfect and flavorful .. You don't have a good Barrier Ninja as of this moment like Darui, Mei Terumi or Danzo tho you have Edo Tensei Haku but he's too squishy to use in arena .. For now, try to upgrade star and skillbreak fully your kurenai so that you c*e her with WaterMain and HinataGNW, then find another ninja to use, maybe Itachi Anbu ..

Don't mind the Ranked Arena for this time being, and focus on the other things for now .. Time will come that you will get good ninjas for you to use and when that happens, then that's the time where you can grind so hard to get the highest rank Six Paths ..

Yes, that's true, if you're still at the stages where you still have equipments that has refinement of 4 to 7 then you must redeem Medium Refines from Monthly Events instead of getting Seal Scrolls .. But once you get past refinement 7 to all of your equipments then feel free to redeem Seal Scrolls or Summoning Scrolls in the Monthly Events ..

Yeah, i agree with you .. I used that team too before when i was still on my early stages (Lv 50 to Lv 70) .. Actually, the Lightning Main, Sasuke, Kimimaro and Jugo team or the Cursed Mark team is the most powerful F2P in early stages of game ..

You have 2 options to get iruka but 1 of them is most recommended ..

1) Thru Treasure of the Sage Event - This one allows you to buy Iruka Fragments at discounted prices, 10% to 30% ..

2) Thru Fragments Refining - This method is the most recommended way to get Iruka, since this method is Free tho it will take time before you can actually recruit Iruka .. This one is also my suggestion for you to do ..

Go to your Ninja Interface and go to Train Tab .. At the upper part of your interface, you will find the Fragment Refinement there .. All the excess fragments of your 5 star ninjas will be available and appear there for you to use for refining, choose all the ninja fragments you want to use to refine and click the "Fragment Exchange Pts" to convert it into points, then choose the "White/Silver" Medium Refining for you to get 10 Iruka Fragments and 2 Seal Scrolls or 4 Summoning Scrolls ..
