15w44b[1] is the thirty-eighth snapshot for Java Edition 1.9, which was released to make various items available in survival and to fix bugs and crashes. The development team's aim had been to have the 1.9 release feature-complete by the end of October 2015, followed by a period of bug-fixing,[2] and this snapshot was the last snapshot before the end of October.



Luck potion
  • Gives the Luck effect for 5 minutes.
  • Also comes in splash and lingering potion forms as well as for tipped arrows ("Arrow of Luck").
Uncraftable Potion
  • Has no effect, unknown use.
  • Cannot be obtained in survival.
  • Has tag Potion:"minecraft:empty".
  • Also comes in splash and lingering potion forms as well as for tipped arrows (just called "Tipped Arrow").
Tipped Arrows
  • Now exist for mundane potions, thick potions, and awkward potions.
    • None of them have any effects and are uncraftable since lingering potions of these kinds do not leave a cloud behind.


Status effects
  • New status effects: Luck and Bad Luck.
    • Increases/Decreases the luck attribute by ±1 per level.
    • Has a clover icon for luck.
    • Has a withered clover for bad luck.


  • generic.luck, ranging from -1024 to 1024.
    • Used when processing loot tables along with the quality or bonus_rolls tag. Currently used for opening chests and chest minecarts, fishing, and player-killed mob drops.
Loot tables
  • Added bonus_rolls tag, to give additional rolls on a pool with good Luck (or to remove rolls with bad Luck).



End rod
Hay Bale
  • Falling onto a hay bale does only 20% of normal fall damage.
    • The highest the player can fall, and live, without armor, is 100.27 blocks
    • The highest the player can fall with feather falling is 169.19 blocks


End crystal
  • Can now be crafted using an eye of ender in the middle, a ghast tear on the bottom and 7 glass blocks on the remaining squares.
  • Are no longer dropped by undead horses.
Fire charges
  • Once again shoot as blaze fireballs when ejected from a dispenser (since 15w33c they had shot as ender dragon fireballs).
  • Removed many unused base potions from the game.
Tipped Arrow
  • Can now be obtained in survival.
    • Splashing down a lingering potion first, then shooting regular arrows through that cloud will give you a tipped arrow back.
  • For effects with duration, the duration is 18 that of the corresponding potion.


  • Rare drops from player kills on normal guardians are returned to what they were in Java Edition 1.8, namely, they only include fish, and not fishing junk or fishing treasure.
  • Horses, donkeys, and mules drop 0–2 leather, affected by Looting, which is a return to pre-15w43a behavior.
  • Skeleton and zombie horses no longer drop end crystals; they again drop 1 bone or 1 rotten flesh, respectively.

Command format[]

NBT tags
  • Entity: Arrow
    • Potion (string): Potion effect of the arrow
      • e.g. /summon Arrow ~ ~5 ~ {Potion:"minecraft:long_invisibility"}.
    • CustomPotionEffects (list): List of custom potion effects.
      • e.g. /summon Arrow ~ ~5 ~ {CustomPotionEffects:[{Id:1,Duration:100}]}.
  • Entity: AreaEffectCloud
    • Potion (string): Potion effect of the AreaEffectCloud.
      • e.g. /summon AreaEffectCloud ~ ~5 ~ {Potion:"minecraft:long_invisibility"}.


  • TippedArrow has been removed. Arrow is used instead.
  • Luck of the Sea and the new Luck effect affect fishing again, and effects stack. Each point increases the weight of treasure by 2, decreases the weight of fish by 1, and decreases the weight of junk by 2.


Loot tables
  • Replaced luck_multiplier with quality.
    • Formula is now weight += quality * luck, formerly weight += weight * luck_multiplier * luck.
