thats true but what of the tatoo? does it have draw backs as well? and the biju does have flaws for example gaara cant sleep because of it, and it runs the risk of the jinjuuriki being taken over by it
1.) Bijus - You can buy a Neko (two tailed demon), Shukaku, or a Kyuubi at different ranks in the game.
Play longer and save up gems/gold. You may be able to afford one.
Also the Neko and Shukaku in game have a certain time they last.
If they run out of that "Time", you need to feed them or continue with no mount. After that you have the time back for that same period.
2.) Tattoo and CS - One of the biggest game secrets. We cant tell you its effects, drawbacks, or how to get it.
All i will tell you is that it comes later in the game as well.
