Celestial opal

This opal is the opposite of the void stone. This stone has a 1% chance of spawning in a flower forest. It can heal anything. And flatten out the obsidian pillars but not destroy them completely. This stone can shoot yellow blasts of energy to destroy part of the pillars or to knock back mobs. If a player has both the void stone and celestial opal the pillars will become a yellow version of obsidian that decay anything around them.
