TaiJustsu is another art and talent set that ninjas can pull from.
They're a few styles of Taijutsu that offer different results in combat.
Below I'll give some basic knowledge of the Taijutsu styles.
Chakra: Chakra is the natural bodily energy, Very much like Mana. Chakra and Mana are both a force of magic. The Mages just manage to harness Chakra in a different way. Ninja Ginjutsu users use Chakra to call upon Summons or activate Ginjutsu attacks and effects very similar to Magic spells.
Analyze Chakra/Mana: Upon Successful INT test, Allows the user to ID a magic item, weapon, or caster.
Stop Chakra/Mana: Upon successful unarmed WS test, Allows user to cease use of Magic/Ginjutsu in target. Target may contest with a toughness test. Upon Failure target can not cast Magic/Jutsu for 1 d6 turn duration.
