Called while the Maulotaur is charging.
If counter 0 is nonzero, it will spawn a HereticPhoenixPuff at actor's origin and give it +2 vertical velocity. Then, its 0 counter will be decremented.
Otherwise, it will remove the SKULLFLY flag, stopping charging. It will go to the see state.
This means that the 0 counter and successive MinotaurCharge calls can be used to control the charge length.
