NIWA is hosting a cross-wiki event this weekend (September 22-24). Details here.
The Yggdrasil Leaf (also know as the Leaf of the World Tree) is a recurring item in the Dragon Quest series. The leaves take their name from the World Tree of Norse mythology.
Yggdrasil Leaves are used to revive characters who have been killed in battle. Due to their usefulness, Yggdrasil Leaves are by far the rarest nonessential items in the game; they cannot be purchased, only collected from chests, and in many cases the player can only ever find one or two in the entire game world. In games where the World Tree can be climbed, a player may obtain a leaf by searching in the fantastic foliage.
The leaves first appears in Dragon Quest II. The greater tree is located in the single forest tile on an island east of Wellgarth, and players can pluck one by searching the spot. In the remakes of Dragon Quest II, there is a newly added sub-quest which requires the player to acquire the leaf at least once in order to cure the Prince of Cannock's catatonic curse.
In III, the leaf can be found in the large forest area in the portion of the world map that corresponds to real-life China. Within the forest, the player must search at the intersecting tile of 4 single mountain tiles.
In the original version of Dragon Quest III, an additional leaf could be found in the world of Alefgard. By searching in the same tile location the leaf has in the light world, a duplicate can be found in the dark world. This glitch was fixed in the remakes of III.
A leaf can easily be found on the branches on the Yggdrasil tree itself, though only one can be obtained at a time. In the remakes players can have three at once provided, that they get one off the branches, and get the other two which are found by:
In VI, the leaf is available as a casino prize at two of the three casinos in the world. It costs 1,000 casino tokens, and the party is not limited to one leaf as in other games.
By a certain point in the game, Yggdrasil leaves can be bought from the item vending machine on board the Albatross. They can also sometimes be found in the wild.
