to complete this category, you would have to defeat all events (except frost legion (because it sucks)) as fast as possible, subcategories would be glitchless and glitches.

would these be the events? Goblin Army, Old One's Army, The Torch God, Solar Eclipse, Pirate Invasion, Pumpkin Moon, Frost Moon, Martian Madness, and Lunar Events?

The end game events are quite hard when under-geared, so the fastest route would most likely require ML gear. But that would make the run very similar to the category AB&E (All bosses & Events) which we already have on category extensions.
