Breaker Block

The Breaker Block breaks blocks below it whenever it's activated by redstone,. The block can be pushed by pistons and can stick to Slime and Honey blocks.

Whenever it breaks a block, it'll drop the item as if the player broke it (Stone into Cobblestone, for example) and the dropped item will be where the block originally was.

This mod is free to use in any modpack, provided that you include proper credits.
