In Minecraft, the Wither Storm is a powerful and dangerous boss mob that can be created by the player. It is similar to the Wither, but much larger and more powerful. The Wither Storm was added to the game in the 1.4.2 update.
The Wither Storm is created by placing four Soul Sand blocks in a T-shape, and then placing three Wither Skulls on top of the Soul Sand blocks. The Wither Storm will then spawn and begin attacking the player. The Wither Storm is immune to all forms of damage, except for the damage dealt by the player’s sword.
