Blaze

"Alchemy addicts and experience farmers are among the few who might have good things to say about the blaze, a ferocious, flaming mob that spawns in the formidable Nether Fortresses. There they patrol, to unknown purpose, aggressively flambéing any and all adventurers who enter their domain."

- Marsh Davies

Blazes are hostile mobs found in the Nether.

Spawning
Blazes can spawn naturally in nether fortresses at a light level of 11 or less.

Monster spawners
Blazes spawn from spawners found in nether fortresses. They can spawn in a 9x9 area around the spawner on the same level, one level higher and one level lower.

Drops
When killed by a player or tamed wolf, a blaze may drop one blaze rod. Looting increases the maximum drop by 1 per level. Blazes which are killed by other causes will not drop anything. In the Console Edition, they also drop 0–2 glowstone dust.

They also drop 10 experience when killed by a player or tamed wolf.

Behavior
Although blazes are able to fly, they will stay on the ground or sink down slowly in the air when not attacking. Blazes will not attempt to swim upwards in lava or water, unlike zombie pigmen. Despite taking damage from water (see ), blazes will make no attempts at their protection if somehow pushed or dropped into water. Blazes' pathfinding does not avoid fire, avoids water like other mobs avoid lava, and treats lava like other mobs treat water.

Blazes will target players within 48 blocks. If a blaze is damaged by a player or other mob, it will alert other blazes within 48 blocks to target the attacker. When a blaze has a target, it will begin flying (attempting to remain 0.5–3.5 blocks above the target) and slowly approach the target.

The blaze's normal attack is a trio of fireballs, shot from up to 16 blocks away. Blazes will shoot even without line of sight to the target. When using this attack, the blaze will catch fire for 3 seconds, shoot three fireballs over the course of 0.9 second, then extinguish the fire and wait for 5 seconds before attacking again. A blaze shoots its fireballs with roughly the same lack of accuracy as a dispenser; however the blaze's shots maintain the same speed all the way to the target, unlike the dispenser's which starts slow and accelerates.

Blazes within 2 blocks of their target will instead perform a melee attack that does damage on normal difficulty, once per second. This attack is not considered fire damage and will not ignite the target.

Blaze fireball
Blazes shoot fireballs at their target, which deal on all difficulty levels. If the fireball hits a block fire will be placed adjacent. If it hits an entity, the entity will take of fire/projectile damage and will be set on fire for 5 seconds, which typically does an additional  damage over time.

Data values
Blaze fireballs are also entities which have associated entity data. Their entity ID is.

Combat
In addition to normal weapons, blazes can be hurt by snowballs, taking damage per hit, and by splash water bottles, taking  damage per hit. They are also damaged by water and rain by every half second. Like most Nether mobs, they are immune to fire and lava.

Data values
Blazes have entity data associated with them that contain various properties of the mob. Their entity ID is.

Trivia

 * When throwing a potion of invisibility on a blaze, the smoke will stay visible.
 * Blazes can fight each other if one accidentally hits another with a fireball when not fighting a player.
 * According to Jeb, blazes look the way they do because all mobs in Minecraft are cuboid-shape, so to make them flame-like and magical, he created them as a core surrounded by rotating rods, and he gave them eyes so they had personality.
