15w44b is the thirty-eighth snapshot for Java Edition 1.9, released on October 30, 2015^[1], which adds the Luck and Bad Luck status effects, makes various items available in Survival, and fixes bugs and crashes.

Potion of Luck

• 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.
  • Have no effects and are unobtainable since lingering potions of these kinds do not leave a cloud behind.

Status effects

• New status effects: Luck and Bad Luck.
  • Increase/decrease the luck attribute by ±1 per level.
  • Luck has a clover icon.
  • Bad Luck has a withered clover.

Attributes

• 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

• Can now be crafted using a popped chorus fruit in the bottom and a blaze rod on top.
  • Yields 4 per craft.

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 crystals

• 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).

Potions

• Removed many unused base potions from the game.
  • For a full list, see removed features.

Tipped arrow

• Can now be obtained in Survival.
  • Splashing down a lingering potion first, then shooting regular arrows through that cloud produces a tipped arrow.
• For effects with duration, the duration is ¹⁄₈ that of the corresponding potion.

Guardians

• 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.
  • Elder guardians still drop junk and treasure.

Horses

• 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.

NBT format

• 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 cloud.
    • e.g. /summon AreaEffectCloud ~ ~5 ~ {Potion:"minecraft:long_invisibility"}.

Entities

• TippedArrow has been removed. Arrow is used instead.

Fishing

• 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.
