Arrows shot from a Flame bow are on fire when shot, set fire to mobs they hit, and deal 4 fire damage over 5 seconds. Fire damage applies after initial damage, similar to Fire Aspect for melee weapons. Creatures killed by fire drop XP only if a player dealt non-fire damage to it within the past 5 seconds.
Unlike flint and steel, flaming arrows affect only players, mobs, TNT, and campfires. No other blocks catch fire. For example, a flaming arrow shot into a tree will continue to burn without igniting the tree. Flaming arrows do not produce light.
Flaming arrows become normal arrows if fired through water or rain.
