Onoki wins this mid diff
--Earth style golem to stall orochimaru whilst he prepares jinton to atomise him, thats all there is to it
Golems get constricted with snakes.
Weighted Rock is countered by Orochimaru shedding a new body.
Cut him in half with Jinton? He grows another body.
Onoki can't land a fatal attack on him to put him down and Orochimaru will outlast him, since most people abuse the flight argument.
