Eternity Mode
Eternity Mode is a higher difficulty mode in Fargo's Souls Mod, initiated by using the Mutant's Gift. The main features of the mode are its numerous changes to enemies, the environment, and bosses to increase the difficulty of the game. Many common enemies behave in different ways and have new attacks, bosses have many more additional changes, and a wide variety of old and new debuffs are employed to inhibit the player.
Conversely, Eternity Mode also provides various quality of life changes and other incentives. Certain items that are normally non-renewable become available as rare drops and many bosses drop helpful items such as crates or potions. Additionally, each boss and event has unique item associated with that exclusive to Eternity of which eventually combine into a powerful soul accessory.
General Changes
Main page: Eternity Mode/General Changes
Eternity Mode has a wide number of general changes to the game on top of Expert Mode. This includes adjustments of vanilla mechanics, buffing certain hostile projectiles, rebalancing existing weapons or equipment, as well as a wide variety of quality of life changes.
Prominently, spawn rates are slightly increased overall but are generally disabled while any boss is alive. All enemies and bosses drop more coins on defeat. Many strong weapons from the base game have their stats adjusted so that weapons on any one tier are closer to each other in terms of performance; in certain biomes will inflict mild debuffs on players in them, though these debuffs can be resisted or disabled by various means.
Enemy Changes
Main page: Eternity Mode/Enemy Changes
Eternity Mode makes changes to almost every enemy in the game. They have new behavior, more intense movement, new attacks, or new gimmicks to make the game feel fresh again. Enemies may spawn other enemies when defeated, attack more often or with new projectiles, or have complicated new attack patterns and function as pseudo-minibosses with additional new loot as well.
Many enemies inflict debuffs with their contact damage, projectiles, or the new Aura mechanic. An enemy with an aura will inflict a debuff on any player that is within the aura, which is denoted with a glowing ring. Some enemies will have reverse auras, which instead debuff players that are too far away. The direction of an aura is denoted by the movement of the glowing particles it produces.
Boss Changes
Main page: Eternity Mode/Boss Changes
Eternity Mode heavily reworks all vanilla bosses. While they retain some of their original behaviors, they have many new attacks, adjusted movement, or new gimmicks that build on the existing to rework the flow and feel of the fight.
Upon activating Eternity Mode, all vanilla bosses will have new recolored sprites, inspired by existing enemies in Terraria, as well as references to other media. For example, the recolored Queen Bee is a reference to her early concept art sprite, while the recolored Skeletron is a reference to the Lich boss from Enter the Gungeon.
The recolors can be disabled if Eternity Mode is disabled, or the recolor configuration option is set to false
In addition to modified existing bosses, Eternity Mode drastically increases the power of bosses introduced by Fargo's Souls Mod. Details on the changes for each boss can be seen on their respective pages.
Eternity Mode also allows all bosses to drop their Master Mode-exclusive items.
Debuffs
Main page: Debuffs
Eternity Mode adds debuffs to many enemies. attacking makes debuffs wear off twice as fast and damage over time effects will not deal damage below 10 health.
Masochist Mode
Masochist Mode is a difficulty that is unlocked after defeating Mutant (boss) on Eternity Mode, and activated by using the Mutant's Gift on Master Mode. Masochist Mode changes will be listed in orange on each respective page.
Masochist mode enhances the 
Mutant Nibble debuff, causing it to inflict one of ten debuffs.
