Not-So Gentle Fist: While the Gentle Fist of their banished brethren is much more feared and well known its roots lie in the Taijutsu Style of the Otsutsuki. This style is considered to be much more offensive in nature than the rather passive Gentle Fist despite the two styles being extremely similar. Due to the strong emphasis on using chakra to damage the opponents tenketsu and internal organs, a user of this fighting style will completely bypass the durability stat of an opponent.
Forgotten Knowledge: The Otsutsuki Clan possess the single greatest library in the known world, and within that library are countless books filled with knowledge of chakra that was once thought forgotten. With this ancient and forgotten knowledge, any Otsutsuki can become a force to be reckoned with (user gains a second Secondary spec in place of a second Tertiary spec).
Almighty Chakra: The Otsutsuki Clan are widely known and feared for many reasons, one of which is their unnaturally potent chakra (+50 Chakra)
