🔧 Mechanics
🛠️ Disabled item break
Tools no longer disappear after breaking, unless they have a 
«Curse of Vanishing». An item with zero durability remains in the inventory but cannot be used to perform its function until it is repaired.
🌬️ Bottled Air
When filling 
Glass Bottles with water underwater, the bottles replenish some air.
Drinking water underwater automatically refills an empty bottle, turning it into a 
Water Bottle. The same applies to crafts that give out empty bottles as a result.
If you hold a 🔥hot item in your other hand, the bottle will not refill with water, but may burst.
🌈 Immersive Dyes
Dyes can be applied onto dyeable placed blocks with RMB.
Dyes can be applied onto dyeable items in 
Item Frames with RMB.
Shulkers can be dyed.
When possible, 
Paper will remove the color.
There’s 8% chance that the dye will be removed upon use.
Most dyeing recipes were removed.
Additionally, using 
Slimeball on a 
Piston will turn it into a 
Sticky Piston.
♨️ Immersive tools
Some tools like 
Clocks, [🛠️]Lunar Clocks, 
Compasses, [🛠️]Depth Meters, [🛠️]Barometers, [🛠️]Thermometers, [🛠️]Speedometers, and [🛠️]Luxmeters show detailed info in lore, optionally on screen, and when interacted.
Additionally, F3 debug screen no longer displays information like coordinates if the player doesn’t carry all the aforementioned tools.
✨ «Fire Aspect» acts as Flint and Steel
«Fire Aspect» enchantment allows using the item as a 
Flint and Steel.
This also includes an Enchanted Book with a stored enchantment, though it also sets the user on fire for 3 extra seconds.
🧩 Miscellaneous
✂️ Don’t run with scissors!
Shears inflict damage when attempting to run with them in your hand.
🔥 Flint and Steel ignites entities
Using (RMB) Flint and Steel on a mob while sneaking or crawling will set it on fire.
🕯️ Lit items ignite surroundings
Attacking mobs with lit 
Torches (of any kind), 
Campfires, or other burning items (including «Fire Aspect» enchantment, enchanted or stored) will set it on fire.
Lit items can also burn 
Cobwebs via RMB.
Better Shovels
Flowers and replaceable blocks no longer prevent 
Dirt Path creation.
Dirt Paths and 
Farmland can be converted into 
Dirt by using a 
Shovel on them while sneaking. The Shovel will lose durability with a 10% chance.
Using (RMB) a Shovel on a 
Snow Block will remove a layer from it, dropping a 
Snowball.
🧑🌾 Better Hoes
Flowers and replaceable blocks no longer prevent Farmland creation.
Using (RMB) a 
Hoe on grown crops will break the crops and replant the seed if the crop has dropped its seed or the player has seeds of the same crop in their offhand or hotbar.
🤺 Piercing blow
Items can now attack through grass and other vegetation. If the item is a melee weapon, the targeted block won’t be insta-broken.
📖 Readable books in item frames
Books placed in Item Frames can be read with RMB.
📓 Book formatting preview
You may preview the Book’s formatting (i.e., how the book would look after signing) by using RMB while sneaking.
🫗 Bottle retrieval
Bottled items (e.g., Potions, 
Honey Bottle, etc.) can be turned into an empty Glass Bottle when placed in a crafting grid. Being underwater will produce a Water Bottle instead.
🪣 Fragile Buckets
Buckets come in various materials (yes, including [🛠️]Chainmail Bucket) and have durability.
🔥 Hot items
Some items are considered 🔥hot: they can’t be held without 🧤Gloves and interfere with bottled air.
🗺️ Dynamic map height
Maps created in dimensions with a ceiling like Nether, show blocks at a height the 
Empty Map was used at.
🪖 Armor and environment
Wearing armor prevents some environmental damage:
- Damage from
Cacti when wearing boots or leggings (depending on where the damage comes from). - Damage from
bushes when wearing boots and leggings (or the whole armor set when crawling).
