|Tool||Pickaxe (Silk Touch required)|
The Clunkhead Altar is a boss spawning altar.
A Clunkhead Altar can be mined with a pickaxe enchanted with Silk Touch. If mined without Silk Touch, or mined without a pickaxe, it will drop nothing.
A Clunkhead Altar can be found in each Clunkhead Arena.
The player can use a Mega Rune Stone on the Clunkhead Altar to spawn the boss Clunkhead. Clunkhead will spawn 1 block away in the negative x and z directions, and one block above the altar, and the Mega Rune Stone will be consumed.
In order for Clunkhead to spawn, the Clunkhead Altar block must be placed in Runandor, and the difficulty must not be Peaceful. If either of these conditions are not met, then Clunkhead will not spawn. Being in creative mode will not override these condition requirements.
