The Candle

The Candle is an unlockable activated Item.

Effect

 * On pressing a fire button, a blue flame projectile will fire in the chosen direction that deals significant damage to enemies it comes in contact with, extinguishing itself after a fixed time of approximately two seconds.
 * The flame deals 23 damage per damage tick.
 * The average damage done by this item is about 115 with the maximum damage possible being 184.

Trivia

 * The Legend of Zelda, a major inspiration for The Binding of Isaac, also has a blue candle item that can be activated once per room to create flames for burning enemies and bushes, as well as lighting dark rooms. Unlike in Isaac however, the red candle is an upgrade of the blue one, which can be activated any number of times per room.
 * The Red Candle is a variation of this item unlocked after donating 400 coins, diminishing on damage dealt instead of time.
 * The Candle was an item in The Binding of Isaac: Wrath of the Lamb where it used to be the only auto-recharging item.
