the skill books system won't come until they release the actual system for it, I don't know why they released the six break through like that. once the system is properly in place you will need coupons to pull for skill books like a lottery system, also anyone saying they will listen to our suggestions is either wasting our time or they themselves don't know because if they release skill books for frags then 90% of the player base will get their ninjas broken for free, oasis is a company and I said it here first the majority of skill books won't be released until 4.0, plus some ninjas like the sound 5 (who desperately need skill books) Don't even have them even in other versions.

lmao Danzo will be the OG ninja once his books arrive But he is a rare so his books will cost around 150-200$ average.
