The Realistic Update is an update that drastically changes weather, mob behaviors, block behaviors, and player stats to make the game more realistic, especially for a survival game.


There are 20 types of weather:

There are variables called pressure, dropping during storms, wind speed, increasing during storms, and temperature, often increasing while near a smoldering forest.

Weather Function
Clear None
Partly Cloudy Dims light by 1
Overcast Dims light by 2
Light rain/snow Dims light by 3
Rain/snow Dims light by 4
Storm/Snowstorm Dims light by 5
Severe Storm/Severe Snowstorm

Dims light by 6 (17% chance to spawn Hail per hour)

Hail DPS = 1 if outside
Tornado Gray column zooming around the world, blowing entities and objects caught in its path, DPS = 3 if inside tornado, fall damage included
Monsoon Only found south of Y - 2000 and north of Y - -2000. Dims light by 4.5
Quake Creates a crack in the ground, forming a new canyon
Sinkhole Creates a hole in the ground, opening up a cave
Tropical Depression Only found south of Y - 1000 and north of Y - -1000. Dims light by 8, picks up Dirt, Wood, Stone, Grass, Glass, and other easily breakable objects.
Tropical Storm Like a Depression, but light is dimmed by 9, and can now pick up Coal, Gold, Talc, Copper, and other ores with a strength of only 6 or lower
Hurricane Like a Tropical Storm, but light is as dim as night, and can pick up any object up to strength of 14
Severe Hurricane Like above, but picks up any object up to a strength of 16
Wildfire A tree has a 1/48682 to start sparking every tick, and fire can spread through trees. A wildfire that is large enough (has burned about 70 trees) will have an orange haze with smoke flying out.

Inflicts blindness for the duration of the Blizzard. This blindness is called Blizzard Blindness, white haze instead of black. It snows extremely heavily. Also, blindness is ONLY inflicted outdoors or if in a house with open doors.

Block Behavior Changes

Blocks will behave different including:

  • Hay Bales - will drop 10 Hay if windspeed is greater than 14
  • Fire - spreads 30x faster
  • Water - rises during storms, lowers after storms, also rises by 1 block every 12 hours and drops 1 block every 12 hours, indicating tides
  • Ore - if left near lava, it can turn Polished, which if crafted into armor, has Polished armor, three more defense than if not polished
  • Dirt, grass, and sand - flammable, but will turn Coarse Dirt if left in flame, sand will turn into glass
  • Lava - Melts, or destroys the following objects - All objects except water, obsidian, bedrock, and ore + ore blocks and Nether materials
  • Mercury - poisons all objects if entered for 20 seconds, Fatal Poison III
  • Uranium - if mined, turns into Liquid Uranium, with the same effect as Mercury but with Fatal Poison II
  • Air - will be only in limited amounts deeper underground, completely absent by 14 Y, need an Oxygen Package Suit to survive, which is crafted with 10 Iron bars, 10 coal. It can only be used for 365 seconds before running out of air and having to go to sockets in caves or to the world surface. Air is also absent in the End and is too hot to breathe in the Nether, so the Oxygen Package Suit must be upgraded to the Thermooxygen Package Suit which can protect from Nether heat. If left unguarded in nether heat, good luck being on fire. Air is also scarcer the higher you go.


  • Central Point Supervolcano
  • Radioactive Biome - full of Thorium, Uranium, and other radioactive elements. Air inflicts Poison if entered, so a Oxygen Package Suit is required.
  • Mountain Range Biome - full of Stone, Andesite, Granite, and Diorite. Has many mountains that tower over 210 blocks but less than 256, many with snow caps. A Mount-Everest type mountain is found in the center of this biome, towering over 300 blocks!
  • Hot Savanna - full of Dry Grass, Stripped Wood acacia trees, and many wildlife, including Parrots, Chickens, Pigs, Cows, Sheep, and other animals can be found here. Lakes are in relatively large amounts here
  • Wetlands - full of Wet Grass and lakes. Frogs are abundant here.
  • Town - Cluster of villages.
  • Volcanic Biome - Nether-hot air, full of granite, rhyolite, andesite, cinnabar, and pumice. Has multiple short mountains with holes leading to a gigantic pool of lava.
