Surprised I didn't get hit at 1:21. Old Hero is another interesting boss, a gimmick that technically can be removed by not having Thief Ring. It trivializes the fight so maybe one day I might try something without it, just to see how much harder the boss is. The strategy was easy enough where I was just like "eh, fuck it" and decided to do no sprint too. He's a mostly consistent boss but is kinda hard to read sometimes, might work with lower damage.
