Terraria servers offer four difficulty modes to choose from: Journey, Classic, Expert, and Master. These determine how challenging the game world is.
Journey: The most relaxed, creative-style mode. Players start with upgraded tools, wings, and can duplicate items. Journey mode allows you to adjust time, weather, spawn rates, and even infection spread. Only Journey characters can join Journey worlds.
Classic: The standard Terraria experience and the default difficulty used as a baseline for all others.
Expert: Enemies are tougher, with double health and damage. Players gain extra loot from enemies, an additional accessory slot, and exclusive expert-tier items. Players drop 75% of their coins on death and regenerate health more slowly.
Master: The most challenging difficulty available. Enemies have 250% health and deal 250% damage. Players gain two extra accessory slots but drop all coins upon death. Master worlds include all Expert rewards plus exclusive fiery red rarity items.
