General

• Ore veins are much rarer but much larger
  • This is to encourage exploration to find a given ore
  • Also helps reduce compulsion to be excessively frugal with resource spending, especially early-game
  • Ore placement is largely identical to "vanilla", but with a slightly compacted Y range for each ore, to create noticeable strata
• Some ores (eg Ruby) do not spawn, and can only be obtained as byproducts via the RotaryCraft Extractor
• Charged Certus and Fluix can only be obtained via Satisforestry resource nodes
• Botania flower generation is more clustered, with all flowers spawning in rare, dense patches
• The ocean floor is now a mix of clay, gravel, sand, and dirt, rather than pure gravel
• TiC gravel ore does not spawn on the surface, but embedded in worldgenned gravel
• AE Meteors do not spawn
• IC2 rubber trees now only spawn in swamp and jungle biomes
• BugFix: Chisel stones can now be overwritten by ores
• Natura trees now treat Ender Forest as forest
• Streams: Biome-specific spawn rates
• Nether, End, and Twilight Forest seeds reset on dimension deletion
• Cave spawns are now biome-specific
  • Some biomes have far fewer caves than average
  • Some biomes will have far fewer ravines than average
  • Some biomes will have larger cave "holes" than average
• ProjectRed marble and volcanoes will not spawn

Biomes

• Biomes are on the "large" setting
• Climate Zones do not apply; biomes are randomly distributed
• BoP Loamy Grass does not spawn as the surface block in biomes, but instead generates as patches in those biomes

• BoP Coniferous Forest is less hilly
• Rainbow Forest animal density halved
• Added wide rivers and beaches
• Reduced ocean frequency

Structures

• Villages are 25% rarer
• Stronghold count increased to 24, in a much larger set of rings
• Each TerritoryZone territory now has additional strongholds forced to spawn within its borders, ensuring every player has some

Dungeon Loot

• Progression-related items such as steel and alloy ingots do not spawn
• Rarer or more difficult-to-find loot tables have more lucrative content added to them, some of which is unique to them
  • Mineshafts have midlevel tech items and powerful mining tools
  • Strongholds contain...rare secrets
• A few structures have resources which spawn in their chests, and can be found via no other means
• "Annoying" items such as unstackables and worthless garbage are less common or removed entirely
• Forestry saplings and crates are added to several tables, to provide progression-locked caches of material
• "Tech oriented" locations can now spawn basic tech items like gears and ic2 circuits
• "Magic oriented" locations can now spawn basic magic items like ThaumCraft phials
• Dungeon loot features MystCraft pages, if installed
• TC loot bags are much more common in their applicable spawn locations
• TC loot bag drops completely redesigned

ThaumCraft

• Eldritch Rings do not spawn in the overworld; they spawn with a custom MystCraft page if installed, the Twilight Forest if not
• Hungry and Tainted nodes will not spawn
• Taint biomes will not spawn
• Totems are much rarer
