Chisel mod adds a huge variety of static blocks to the game. This mod will be very useful for people who like the construction aspect of Minecraft. Chisel mod also adds two new other items, the Ball O’ Moss, and the Cloud In a Bottle. Right clicking these items will throw them, in the same way as how snowballs are thrown. On impact these blocks will do a variety of different things. The Ball O’ Moss will mossify all the nearby blocks, for example, turning Stone Brick into Mossy Stone Brick, and the same with Cobblestone. The Cloud in the Bottle with create a large amount of clouds on impact.
Access to new blocks is provided mostly through one tool: chisel. The chisel is created with a iron ingot and a stick in a diagonal pattern. Right clicking causes the chisel GUI to load.
Place a block in the middle and you may turn it in to other blocks of the same type.
