Crazy Craft for "Minecraft" is neither a mod nor a series of levels to play. It is a collection of mods that drastically change the gameplay and features of the base "Minecraft" game by increasing the difficulty of the game, adding more monsters and adding several types of magic.
The Crazy Craft modpack contains several dozen mods that expand what a player can do while playing "Minecraft." The modpack contains various decoration mods, such as Chisel 2 and Decocraft to widen the variety of decorative blocks a player can place. It also drastically increases the health of monsters found in the game as well as featuring mods to help the player deal with them, such as Equivalent Exchange 3 and Armourer's Workshop.
