Ah, Lucky me i have a cw that let's me do that
I stand up as i focus my raw chakra as i think about how the water looks, how the water feels, how the water sounds, And how the water smells, by doing this i change my raw chakra into water nature chakra. Once this is done i use shape manipulation on the water and shape it into a sword, Once this is done i harden the water to keep it's shape and i swing it towards the fire ball cutting it and putting it out.
A- can be used for both offense and defense.
D- Venerable to lightning while using the sword.
