This was done after multiple missions and an Astral Grind... and an update two days after the initial release of the first build of Shadow Lords, the new "Story Mode" for Killer Instinct (Season 3). This happened after a first completion in Normal Mode with Crafting and learning the system. This was done on the Challenging Difficulty which is below Godlike, the hardest difficulty available.
After finding the right team (preference and initial skill and knowledge) and items, I decided to attempt the Impossible: defeating the All-Buff Shadow Lord himself, Gargos! The Astral God comes with a few adjustments to make him an absolute beast worthy of Shao Kahn, a true final boss with evil laughs, new recapture abilities and... just watch the whole video! I decided to skip all the Missions and go right to the Finale. And boy, he's a pain in the Astral Butt... Here you have the full Replays, I may do a real Boss Rage for the Godlike Difficulty.
Here are the buffs used by Gargos for this specific run: - Shadow Lord (always active) - Claw of Gargos - Heart of Gargos - Wings of Gargos - Eye of Gargos - Blood of Gargos
Gargos can also have other types of buffs but all of them are randomized making each run almost unique. Four buffs can be removed in total by defeating the Omens during the Missions once a portion of the Earth has been 50% corrupted by the Shadow (an Omen will arrive a little later after the initial warning).
