The Forbidden Fragment in Terraria is required to craft endgame items, including the Forbidden Armor, an ideal armor set for magic and summoner builds. However, farming this material can be tricky if you don’t know where to look. Here, we'll cover which mobs drop Forbidden Fragments, their locations, and how to use them!

Forbidden Fragment Locations & Mobs

Introduced in Patch 1.3.3, the only way to farm Forbidden Fragment in Terraria is by defeating Sand Elementals, rare Hardmode enemies similar to the Ice biome’s Ice Golems. These enemies only spawn at the surface layer in the Desert biome and only during a sandstorm. A sandstorm event may occur if the wind speed in the Desert biome reaches at least 30 mph. Also, there’s no manual method to trigger a sandstorm in Terraria. However, a sandstorm typically has a higher chance of starting if it’s raining on the surface layer. Use the PDA, Cell Phone, Fish Finder, Shellphone, or Weather Radio to display the wind speed on the screen’s upper right corner. Additionally, bring the Lifeform Analyzer or its upgrades to help detect if the Sand Elemental is nearby. Thankfully, the Forbidden Fragment is a guaranteed drop from the Sand Elemental. However, some players might not be lucky as they must still rely on RNG for this enemy to spawn.
