"It's weird to think about whether this could be considered a flaw in the game's design, though. On one hand, it's so specific with its setup that it absolutely would never happen unless it's done intentionally, but on the other hand, this doesn't require any fancy glitches or ridiculous exploits. All I did was level up a Pokémon and teach it the moves it wanted to learn. It just so happens that a certain combination of those moves at this stage in the game can completely ruin everything."
Jeez. Leave it to SAO to not only have a Boss that glitches out and dies on its own, but also doesn't even flag THE GODDAMNED EXIT TO OPEN!
