Most of us know EU luke would kill oryx with a thought. I will explain how return of the jedi luke can solo oryx. Luke grabs spark and force jumps up to relic, no need for platforms. Once the 4th ogre spawns he force grabs all of them and slams them into each other with enough impact to kill all of them at once leaving their orbs in the same spot. Vessel spawns, he runs over to grab the brand and force throws the vessel into oryx chest for the stagger, maybe he follows it up with a lightsaber throw if needed. Detonates all orbs at once. Rinse and repeat. Easy. Don't even say the shade will be trouble because it won't be. I can't believe anyone could deny the son of Anakin skywalker would even break a sweat doing this.
