I guess I love suffering and play games only because it's not enough in real life (that's why my favourite genres are souls-likes and fightings, but that's another story). I'm currently playing Expedition 33, and this game marks some areas as "dangerous", implying that the player is underleveled to defy local bosses and mobs. But hey, it sounds like a challenge! The moveset of the first boss I've met was very small—only 3 moves. But that was not the issue here: I dealt very little damage, whereas they simply one-shot me. After two days I finally made it: 37 minutes of patience, and 265 successful parries in my winning attempt. I'm very proud of myself :) It was not the longest time I've spent on a boss, but by far the longest attempt
