Flame is an enchantment from vanilla Minecraft used on bows only. Flame lights the enemy on fire when hit with an arrow unless they're immune to fire. The max level is I (One) and it does 2 and a half hearts or 5 damage per hit with the fire which lasts 5 seconds. Flame may also ignite or set off TNT. Creatures killed by fire only drop XP if a player dealt non-fire damage to it within the past 5 seconds.
