Malice Mode is the third game mode introduced in the Calamity Mod. When activated, it forces all bosses to become permanently enraged and to use modified Death Mode AI. It is activated by using the Malice item, which can be crafted at any Altar and does not have any ingredients.

Malice Mode can be deactivated and activated at will. It does not require any of the other difficulty modes to be active. Attempting to activate or deactivate Malice Mode while a boss is alive will have no effect.
