Where to Find Wind Charge in Minecraft

Wind Charge belongs to Trial Chambers (deep underground), which is one biome and no more for anyone hunting Wind Charge. Depth decides the odds on Wind Charge: the Y -40 to -20 range is where Wind Charge shows up often enough to be worth the tunnel. The relevant structure, a Trial Chamber, generates deep underground in the Overworld and is built from copper, tuff, and exposed blocks of these materials, a useful visual cue while caving. The Breeze is a hostile mob that spawns from Trial Spawners in Trial Chambers. Trial Chambers generate deep underground with copper and tuff construction. In total, Wind Charge can reach your inventory through collecting it as a mob drop and looting it from generated structure chests, so you can pick whichever path your current world makes easiest.

Craft it rather than hunt for it: Wind Charge comes off a Crafting Table from Breeze Rod, 4 at a time, and that grid hands you Wind Charge every single time you fill it in, which no chest or mob will do. Gather first and craft after, because Wind Charge takes Breeze Rod (kill a Breeze in a Trial Chamber) before the grid does anything. Wind Charges can be thrown to create a wind burst that knocks back entities and activates redstone components. Can be used for advanced parkour: throw at the ground beneath you to launch upward. Mob drops reward preparation on two fronts: Looting on the sword for more Wind Charge per kill, and a built spawn area so the next one is never more than a minute away rather than a whole expedition. A full stack of Wind Charge is 64, so gather freely: 27 slots turn that into 1728, and that is a session worth of work stored in one block. One note worth having on Wind Charge and its updates: Added in 1.21 (Tricky Trials Update).

If you are here for Wind Charge, Mace, Trial Key, and Ominous Trial Key are the neighbours worth knowing, since a route to one tends to pass the others. The item page for Wind Charge has the numbers this guide leaves out.
