Terraria Mods Wiki

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.
