Fire Aspect

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

Fire Aspect adds 80 fireticks (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 / damage on level I/II.

The player can use this formula to calculate the Fire damage: Fire damage in = (Level × 4)-1

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.

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