Chisel is a mod that implements a chisel as a tool to add to your repertoire. If you right click with your chisel in hand it will open a GUI that will enable you to change various blocks into up to 24 varieties.

Chisel 2 adds a significant number of blocks to the mod as well as an Auto-Chisel capable of automatically converted blocks into their selected chiseled form (exactly like the hand-held chisel), but it can be automated.

Chisel 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 change all the nearby blocks into their moss variants, for example, turning Stone Brick into Mossy Stone Brick, likewise with Cobblestone.

The Cloud in the Bottle with create a large amount of clouds on impact.

Smashing rock will decay the blocks it hits in a splash area of affect.
