There isn’t a confirmed, reliable way I can verify for Mace Mayhem Roblox specifically, but the usual method for summoning a Wither in Minecraft-style games is to place soul sand in a T shape and add 3 Wither Skeleton skulls on top; that’s the standard Wither spawn pattern.

What to try in Mace Mayhem

  • Look for a summon or boss spawn area in the game.
  • Check whether the game uses the same soul sand + 3 skulls pattern as Minecraft.
  • Make sure you’re using the correct skull type, since using the wrong head item can stop the summon from working.

If it does not spawn

  • Clear the blocks around the T shape so nothing is obstructing it.
  • Try in an area with enough open space.
  • If the game has a custom Wither Storm or event boss, it may use a separate trigger instead of the normal Minecraft recipe.

Practical note

A result tied to Mace Mayhem content suggests this game may include a Wither Storm -style feature rather than a vanilla Wither summon, so the summon method may be game-specific.

Best next step

Open the game’s description, update notes, or community posts and search for terms like Wither Storm , summon , or boss spawn.

TL;DR: Try the normal Minecraft Wither recipe first, but Mace Mayhem may require a custom Wither Storm trigger instead.
