Essence

The essence items are used to make the healer. They are crafted with the hard crystal ball with a life thing (Such as plants - leaves, cactus (And it's dye), sapling, flowers, mushrooms, etc.) to get the essence of life; dirt or grass to get the essence of earth; a water bucket to get the essence of water; a lava bucket, [mcw:netherrack|netherrack], or flint and steel to get the essence of fire; and the air is the hard crystal ball just put in the crafting grid.

As of the snapshots/2.0, you can right click a plant thing (leaves, flowers, tall grass, etc.) with the hard crystal ball to get essence of life, right click lava or netherrack to get essence of fire, right click dirt or grass for essence of earth, and water for essence of water.

These are animated textures.
