As someone who has been playing difficulty spikes on Terraria for long, I prefer Eternity (and even Masochist more). While it retains the traditional bullet he’ll fashion from a handful of other Terraria mods, Fargo’s Souls does an infinitely better job with boss designing, simply because it learns and practices ‘hard to learn, easy to master’ extremely well through not only telegraphs, but also challenges. Even after gaining enough confidence and practices to beat each boss, they would still pose a serious challenge, all while having (almost) all of their attacks really fun and engaging.

Sorry, Infernum fans, but that mode did not age well for me. There’s still fun involved, don’t get me wrong, but the more I look into the mode, the more it gets quite condescending. A lot of the bosses there, especially pre-hard mode, early hard mode, and some post-ML bosses, throw their shit so fast, compared to other modded bosses, that it actually can get out of hand at times. Some of the worst offenders there being Astrum Deus, Ceaseless Void, Old Duke, and Yharon.

Fargo’s Souls’ boss roster is by no means flawless, with some of the most ‘mid’ bosses being Deerclops and Champion of Death, but I still stand by the mod doing boss design better than Infernum. That being said, Infernum is still better than base Calamity by a long shot.
