Moon Fragment

A Moon Fragment is a Hardmode Biome created upon the crash landing of a Moon Fragment crash-lands. This event always occurs off screen, leaving a massive crater for the player to explore. The crater is made up completely of Moonstone ore. The event is triggered when the player has destroyed all three mech bosses, and are alerted of the crash when a status message says: "A shard of the moon has fallen!"

Moon Fragments are huge, dwarfing the Pre-Hardmode meteor biome. It also features several new enemies which pose a threat to the player. A variant of the slime, the Moonwalker, which has additional defense in the form of a armoured body, a flying enemy known as the Orbiter and a crab-like enemy called the Voyager. These enemies can be prevented from spawning if several NPCs are nearby.

Moon Fragment crash sites provides moonstone ore, a valuable crafting material. It requires a Pickaxe Axe or higher to mine. Unlike meteorites, Moonstone does not cause burn damage. However, the biome itself inflicts the Warped debuff, which causes local gravity to act similar to Space.

When most of the Moonstone is mined away, it stops counting as a moon fragment which stops the gravitational effect and ceases enemy spawning.
