The Instability Orb Ore is a rare ore found inside Biome Islands in very small clusters.
The ore has to be mined using a Diamond Pickaxe. Each mined ore has a 40% chance of yielding exactly one Instability Orb and a 60% chance of breaking. The chance of getting the orb can be increased by using Fortune enchantment, with 4% increase per level.
Each successful attempt also yields between 6 and 9 experience.
