Blaze

'Blazes; are a type of mob that appears in The Nether. They are able to float and shoot fireballs at the player. They appear to catch fire just before shooting said fireballs, then "cool down" until they can shoot again. They drop Blaze Rods, and can spawn naturally or from a spawner.

Trivia

 * Lighting has no effect on their mob spawner, as Nether mobs typically do not evaluate light when spawning.
