Help....

So how much TP does Nexus cost to train? I can seem to find it or maybe I am just blind AF

Nexus stats, like before should be 1 TP per attribute.

Element mastery is 3 TP each. Chakra Control, Kekkei Genkais and any other kind of control costs about 4 TP . Nature training itself is 6 TP to train.

Things will also be changing shortly to give a better information for the guides later on. Just continue the way it is until the update comes. But yes its located on the Training Guide under the Guidelines.
