Fairy Bottle

Fairy Bottles are the result of capturing a fairy by swinging an Empty Bottle or a net near one in The Legend of Zelda series that appear as an item in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. By picking one up, the player can heal 100% of damage. However, the item only works if the player has at least 100% damage; if not, they simply hold it. The bottle can be thrown while being held, and if it is thrown at another player that has at least 100% damage then they are healed, otherwise it deals damage upon contact like any other throwable item.
