Shadow Orb

Shadow Orbs are purple floating orbs which are found deep in the crevices of the Corruption. Frequently, to get to them you need to dig through Ebonstone, which is possible by using Nightmare Pickaxe or higher tier Pickaxes, exploding it with Dynamite, or converting it to normal stone with Purification Powder.

Once you reach the orb, you can break it with a Hammer, Bomb, or Dynamite.

The light emitted by Shadow Orbs is also sufficient to bring Deathweed into bloom at any time - during a Blood Moon or otherwise.

Orb Count (Cycle)
Each orb, when destroyed, will leave behind items for the player and, with a 50% chance, cause a Meteorite to fall during the next night after midnight. The following list outlines the cycle of messages and consequences, and is ordered assuming that the world loads with 0 orbs having been destroyed (see bug below):


 * Destroying your first orb will relay the message "A horrible chill runs down your spine...". This also fulfills the criteria for a Goblin Army to attack.
 * On destroying a second orb, the message "Screams echo around you..." appears.
 * On destroying a third orb, the message "Eater of Worlds Has Awoken" appears and the dreaded Eater of Worlds is spawned. Also, the destroyed orbs count is reset.

Drops
Shadow Orbs may contain:
 * Musket and several Musket Balls
 * Orb of Light
 * Vilethorn
 * Ball 'O Hurt
 * Band of Starpower

The first Shadow Orb you break on any given map will always drop a Musket.
