Hey,

Its hard to say what you lack in what feature, due to you the only 1 in your server. At best I could recommend you to ask your group mates that are ahead of you, for example what field on myoboku etc they are, as you then will realize if you are ahead in this feature or actually behind in this feature.

And to answer your questions about the events, in general best event to get ninjas or power items from is Lucky Board. Due to the amount of crazy Magatama's it can give with it, what helps a lot to increase your power as well and not to mention most of the items on the board are really helpful to increase power as well. Although currently a bit outdated some of the items.

And to what should you spend cp on; You should base it on what you lack and where can you get for low cost most benefits out. Currently for most players this is training potions as the stats it gives is overall and not for 1 ninja.

Depending if you are a f2p or low spender. I would recommend to try to unlock all the flags, due because this feature gives a crazy amount of power at the start. With this feature its recommended to unlock first initiative tiles and go to the next ninja of course if you have other ninjas unlocked, and best place on every ninja is to stop on lvl 6 or 7

I hoped this helps you a bit with your question

Thanks for your answer. Sadly, my mates are like "I have no idea". And 1st guy on the server is like "spend EVERYTHING on pos 1 ninja, focus on the Helmet". From my Lucky Board (30k cp), my power's increased by ~2k, so I assume there has to be better way... I'm low spender, but in this game it's so hard to compare BP sources - I have same issues as my friend - I have no idea where the power comes from. I mean, it's hard to specify their contribution in total power. And that's why I come here for some tips

The best way currently to increase power is Training Potions, as i said above u really will notice the difference really fast.
The best events to buy the training potions in my opinion are Color Banner Gift, Lucky Stars, and if you can do 10k Fuku Deals the Anniversary Firework Event

By Fuku Deals, you mean Fukorokumaru Exchange? It gives some premium ninjas on higher spends, doesn't it?

It's possible that other players who are ahead of you aren't focusing most of their resources on their position 1 ninja, therefore their battle power is higher - even if it doesn't neccessarily translates into having a stronger team overall.

Yes Fukurokumaru Deals, and as csillag mentioned higher power doesnt mean somebody is stronger than you, sometimes ppl with 50k + difference even loses, depending on the ninja and substats etc.

Thanks! That actually cover some of my points. Any thoughts when should I upgrade Tactics Grade or when do I perform Purification Breakthrough?

Lvl 6 tactic pages is good so wouldnt really bother.
Purifaction Breakthrough Pill just use on your highest gold, and in general what i personally do with purifies is stack like 999 locks and start purifying till i have gold Ini and than start locking locking from there

So yes this means roll the gold crits/injurys/controls and combo's, and when u get gold ini if you still get a gold combo/control still dont lock that. Lock gold crits and injury's and move to the next set. This is personally how i always did my purifies

Hope this answer some of your questions

Thanks! I meant those secondary updates on tactics, not tactic pages. Idk english name for it...

don't concentrate entirely on position 1

it will decrease your power

so divide ll the magatamas and runes to increase power

also how much power do you have?

how did you complete ninja exam level 199

i am stuck in 128

It's possible they have more stats in the meaningless ones (NIN/TAI Pen.), some people have very high power and lose to others with much less because of that investment in not so meaningful stats just to gain more power.

I have around 71k power. I don't know how to answer your question :p exam is pretty easy, I'm doing it for my teammates.

you forget the most important feature to talk about which is ninja assist you have to gather flags and upgrade all the ninja assist at least to lvl 5-6 this will give you a pure 20-30k power at least

This one is not available on my server yet, but I will keep that in mind :) (on my prev server, UK one, I went for 1010 training, which was a mistake, I assume)

Flags and Training Potions, when you get it will give huge boosts. Otherwise it sounds mostly like your levels are just lower than others your are comparing to. You'd have to ask them to find out how far they are in the other systems.

Also you said you only have 2 outfits so far. Each outfit is roughly a 2K BP, some less, some more. So getting 4-5 more would close that 8-10K gap you are talking about.
