Spoilers for "Infinite Mana in the Apocalypse" around chapter 600
Plot armor is a thing that always exists, however it is up to the author how much they want to hide it. Thus is definitely surprised me a bit when the main character of a novel received the Protagonist trait at around chapter 600. This trait obviously being extremely broken and including numerous insane skills such as plot armor, blind luck and save points. (Not all skills come unlocked directly with many more I haven't mentioned)
Honestly I can only respect such a ballsy move.
