Dragon Kick is one of the attacks Monks can execute while in Opo-opo form, which then changes the Monk to Raptor form, while other abilities use Coeurl form. Using Perfect Balance allows the Monk to open Master's Gauge Chakra from each of these stances, allowing them to use actions like Flint Strike. Additionally, Dragon Kick grants Leaden Fist, which improves the power of certain attacks like Bootshine.
The Forbidden Chakra is an attack that a Monk can use when all five of their Chakra from the Chakra Gauge have been opened, which is gained through an ability called Meditation. The Chakra Gauge can also be spent on other abilities like Steel Peak, Howling First, and Enlightenment.
Phantom Rush is a devastating attack that grants Formless Fist to the Monk, allowing them to use actions without the prerequesite stance. However, it can only be executed when a Monk has opened all three Master's Gauge Chakra in additon to the Solar Nadi and Lunar Nadi, granted from Flint Strike and Elixir Field respectively.
