help with the new Ninja

[Macleod]

You still have to use the Ninjutsu ability after inputing your mudras to activate the ability associated with that mudra combo. The Ninjutsu icon changes to the ability icon associated with each mudra as you're inputting them. Sounds like you need to add Ninjutsu to your hotbar, and I'd recommend putting it right by your mudras so you don't have to move far to hit the button after hitting your mudras.
