The first one is easier than a dark souls, it never really gets to that difficulty (although I did stop at the final boss as it’s gimmick was super annoying) but the first game is kind of based around multiplayer as almost every boss spawns ads constantly.
Yeah, the one that summons a bunch of rat things. The cool thing is you can just refresh the map and get a different boss. Each biome has 2 different bosses both tend to have Adds but usually one is better or worse with it.
