Pneuma Flower (プネウマの花, Puneuma no Hana?) was a rare revival item in Sword Art Online, usable only on «Tamed Monsters». The flower would sprout from the grass of a white stone in the middle of the 47th Floor's northern dungeon, the «Hill of Memories», if visited by a Beast Tamer who had lost their Tamed Monster. Since Beast Tamers were few in numbers, the flower was quite expensive in the game.
To revive a deceased Tamed Monster, the owner of the Tamed Monster has to drip the droplet of water in the middle of the flower onto the pet's «Heart». However, the item is only effective if it is used within three days of the Tamed Monster's death, as after that, the «Heart» turns into «Remains».
