Some items' or groups' chance to drop changes according to the player's gamestage. Here you can see those values for any gamestage you want using the little box below. Just type the gamestage you want in the box and press the Apply!-button. The values should change immediately, if the chance is different.

Current game stage: 1


As of Alpha 13, the Hardness of all blocks was set to 1. The Durability of a block is now determined by hit points (HP) for each block.

Historical Information

The Hardness index of a material determines how much effort is needed to break the material. You can obtain this index using the Item Stats functionality added to the game in the alpha 7.6. To do this, place the mouse over an item to see the Object Stats, including its Hardness.


Hardness is a base data for calculating Durability and Pure-Dur for blocks.


  x = Hardness ÷ Block Damage (Appropriate Tool)
If x = Integer
Then Durability = x + 1
Else Durability = RoundUp(x)
In words: Divide Hardness by the Block Damage of the Appropriate Tool and add one if whole number or round up the quotient.


  x = Hardness ÷ 0.075 (Entity Damage Infected Survivor)
Pure-Dur = RoundUp(x)
In words: Divide Hardness by 0.075 and round up the quotient.


You can use the Creative Menu to consult the Hardness for all the items. Or see Building Materials for an overview in hardness within different building blocks.
