Phantom membranes

Potion of Slow Falling

• Brewed with phantom membrane.
• Gives the player the Slow Falling status effect for 1 minute and 30 seconds.
• Can be extended to 4 minutes by brewing with redstone.
• Brewing it with gunpowder or dragon's breath creates a splash or lingering potion, respectively.

Arrow of Slow Falling

• Effects the shot mob with the Slow Falling status effect.

Effects

• Slow Falling
  • It causes the player to descend at a much slower rate, and not take any damage when hitting the ground.
    • This allows the player to jump further than normal.
      • If the player is sprinting while under the Slow Falling effect, they are able to jump across a gap of over 5.5 blocks, compared to 4 with normal sprinting.
  • Crops don't get destroyed if the player lands on them with the Slow Falling effect.
  • Higher levels do not change the rate of descent.

Advancements

• Added 4 new advancements:
  • Fishy Business: 'Catch a fish'
  • Tactical fishing: 'Catch a fish... without a fishing rod!'
  • A Throwaway Joke: 'Throw a trident at something'
  • Very Very Frightening: 'Strike a Villager with lightning'
• Added three new advancement triggers:
  • minecraft:fishing_rod_hooked triggers when a player reels in an item or entity;
  • minecraft:channeled_lightning triggers when a player uses the Channeling enchantment to strike a mob;
  • minecraft:filled_bucket triggers when a player fills a bucket.

Debug screen

• F3 + C
  • Now gives a warning before forcing a debug crash.

Kelp

• Changed texture.

Elytra

• Now requires phantom membrane to be repaired instead of leather.

Phantoms

• Now drop phantom membrane instead of leather.

Kelp

• Cannot generate anymore in warm oceans.

Seagrass

Enchantments
