Exxo Avalon/Comet

Comets are a  in Exxo Avalon. They have a 1/5 chance to spawn every night at midnight after defeating, or can be manually spawned by using a purchased from the  after Oblivion's defeat; if the player attempts to use a Hydrolyth Trace before Oblivion's defeat, it will have no effect, and restore the item used if there was more than one in the stack. Players are alerted of a comet crash via a : "A comet has struck ground!"

Comet biomes spawn s, which behave like Meteor Heads, flying toward the player and following them as they move, passing through all blocks that they come across. The spawning of Comet Tails cannot be prevented as long as the area is considered as a comet biome, even with several NPCs nearby.

Once most of the comet has been mined away (less than 50 remaining; about 10% of an average comet), the area will no longer be considered a comet biome.

Conditions
In order for a Comet to drop, the world must be in and  must have been defeated, and there is a 1 in 5 chance for one to drop every night at midnight. There also must be no chests nearby (similar to Meteorites).

Trivia

 * The music of comet biomes is overridden by the theme music of, The Corruption, The Crimson, Glowing Mushroom Biomes and Space when crashed there.
