Well, that's pretty high BP compared to mine .. I'm Lv93 with only 79k BP (76k with my current 3rd Raikage Team) .. If you're planning to spend some cash to get more power, choose the events wisely, the events where you can get power-up items like Lucky Board or Lucky Star Wheel is good events, since while spinning or throwing dice, you can get items for power and obtain points for you to use to redeem other power-up items or the ninja fragments you needed .. Also, pick the time for recharging, choose the week where we have the Recharge Events, and/or spend when we have Spending Rebates so that you can earn items and other event ninja fragments .. That's some of the ways but there are other ways to spend wisely ..

I hope that helps you even for a bit ..

yea what the guy above me said, this week when all the events came out together was a good time to spend imo cause 10k ingots would give you lvl 6 attack magas and lvl 7 life which would boost my power (lvl 89 70k) plus lucky board and lucky stars being i still need higher charms and med. refine runes

thanks for the advise.
Till now i did exactly the same thing =)

But wasnt sure how to get like 10k+ Bp withing some week or so.

Im playing on .de serves we dont have such greats events neither such good rebates ^^
when you guys use 100 seals scrols u get 10 back in an event we get 3 back ^^

when u get leve 7 magas we get lv 4 and stuff liek that :)

Then dont spend. Have some respect for yourselves, if they give you bad rewards, dont pay and encourage them.

On topic:

myoboku gifts are propably the best and cheapeast way to increase power in general.

Charms, refines on first position, while giving you less overall power have a significantly larger impact in pvp. You could also pick the most refined gear and try to get its purification to the highest possible level. If you havent done it yet, you can max out mood on your main team (if you are using only 1 set of ninjas for pvp). Also look for tool essences, because they provide a lot of initiative+stat, good deal. I assume your mangatamas are all lv6 and runes around lv5~6 each, so other power sources (mangatamas, runes, purification in general, battle armor, summon cultivation, costumes) are rather expensive for the ammount of power they provide for team. It can still be beneficial to improve your first position even if it gets a little expensive, but at your current stage its not worth to do it on everybody else.

You're saying German version, arent tactics kinda op thing there? Could be worth looking into it.

I need to spend 120 mykobo for 1 thing.

Tactics is going up to 10% withi nsome days but its really expensive.
Magatams and runes are at 5-6.

charms and refines are doable. but therefore i need to wait for a good event :)

Modds are alrd up to 65% all :D

I need to get some hihher stage at ninja exam but i stuck at lv 128 there. ._.

I spend like 2k on ninjas and still dont be able to do that xD
