Minecraft 1.9:arrows, potions and more

Enchanted Golden Apples

• can't be crafted
• found in creative

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).

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.
• Uncraftable Potion
• Has no effect, unknown use.
• Cannot be obtained in survival.
• Has tag Potion:"minecraft:empty".

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").

Tipped Arrows

• Now exist for empty bottles, water bottles, 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.

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.

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.

End Rod

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

Loot tables

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

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 1⁄8 that of the corresponding potion.

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

Guardians

• Rare drops from player kills on normal guardians are returned to what they were in 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.

Entities

• TippedArrow has been removed. Arrow is used instead.
• NBT tags

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