• Only obtainable using /give playername 137
• Can operate in silent mode where it doesn't display commands in the chat box.

Beacons

• Intended as an endgame block
• Continuously glows and gives a selected status effect to players within 16 blocks while beaming a beacon of light directly upwards (as bright as glowstone)
• Activated by building a solid pyramid of iron/gold/emerald/diamond blocks underneath and selecting an effect
  • The cheapest configuration requires 9 blocks, while the best configuration requires 164 blocks
• Has to be directly exposed to skylight to work
• Building square platforms of increasing size and the same material per layer will activate it and increase range and status effect selection
• Viable materials are iron, gold, diamond and emerald blocks
• Changing selected status effects costs 1 emerald, diamond, gold ingot or iron ingot
• Unlockable effects, with increasing amount of required layers of blocks required:
  • Speed and Haste
  • Resistance and Jump Boost
  • Strength
• When all 4 layers of blocks underneath are built correctly, a second status effect can be chosen
  • This second status effect is Regeneration or tier II of the previously chosen effect
• Effects given by the Beacon will have less intrusive particles than others on the screen, such as those of potions

Anvils

• Used for repairing and combining enchanted items as well as for renaming any item/block for experience levels
• Tools can also be repaired using one piece of their material
• Enchantments that are the same are upgraded by one level as long as they are both the same level and the higher level exists
• Conflicting enchantments will be removed and only the first one will be kept
• Becomes damaged from using and dropping it - Damage persists in inventory and splits up into 3 categories: Anvil, Slightly Damaged Anvil & Very Damaged Anvil
• Can be placed in 4 orientations, but can't be moved by pistons
• Experience level cost depends on enchantment levels & rarities, whether the item will be renamed and whether the item has been used with an anvil before - Maximum experience level cost is 39 levels, unless in Creative mode
  • For a more detailed explanation on how enchantments are combined using the anvil, see the Anvil mechanics page
• Is affected by gravity and does 1 heart of damage to mobs and players it falls on per block it fell, excluding the first one - Players killed by a falling anvil cause the death message "Player was squashed by a falling anvil" to appear in chat
• Certain blocks are destroyed when an anvil falls on them: levers, buttons, torches, redstone torches, redstone repeaters, flower pots, rails & mob heads

Flower Pots

• Lets players plant all kinds of saplings, mushrooms, flowers, cacti, dead shrubs and ferns
• Using pick block on it gives the potted plant
• Right-click it with something to plant it, hit it to get both back

Cobblestone walls

• Available in cobblestone and moss stone variants
• Behave like fences - Connect to each other, to other blocks and to fence gates & have a 1.5 blocks high collision box

Item Frames

• Also exist for creepers, zombies, skeletons and players

Carrot on a stick

• Used to control pigs

• Slowly loses durability when riding pigs
• Pigs start slow but end up going about 5 blocks per second
• Can be used to give the pig a short speed boost - This takes up a chunk of the durability
• The pigs ‘eat’ the carrot eventually, leaving the player a fishing rod and will require another carrot to continue riding
