Do you mean during the Onua vs Lewa battle? I don't really now where it can be used but it would be beter agaist multiple targets instead of just one, it could be used in the onua vs lewa if there are many bohroks surrounding lewa. I imagine it something like: lewa sheathes his axe then he kneel a little (like delsin) air appears in his feets, leaves start circling around him ,then he jumps into the air leving a trail of leaves.
