Fire Aspect

Fire Aspect is a weapon enchantment that sets the target on fire.

Usage
Fire Aspect adds 80 fire-ticks (4 seconds of burning) per level to the target. Because the first hit is caused by the item with this enchantment, the first second of fire damage will not be recognized. Targets will be dealt and  damage with level I and II respectively.

Formula to calculate the fire damage: fire damage in =.

When possible, dropped meat will be cooked if the mob is killed while on fire. Experience will only be dropped if non-fire damage was dealt by the player within 5 seconds of the death.

Immune mobs
Both Fire Aspect and Flame are nullified on all Nether mobs, except normal skeletons and endermen, because nether mobs are immune to fire and lava.
