Full list of changes here[github.com]

Major Additions:

• New biome - Ashland Highlands:
  
  • A land of treacherous rocky slopes, dotted with pockets of dense vegetation, and small pools of thermally-heated water. Herds of rotumbo are a common sight here, as is ashen jazbay, which thrives on the rocky soil.
    
  • Generated at high altitudes around dormant volcanos.
• New animal - Rotumbo:
  
  • Mostly found in the new highlands biome.
    
  • Can be milked for milk.
    
  • Added as a potential trader pack animal for all ashland biomes.
• New animal - Ogrim:
  
  • Only encountered in a new wandering ogrim incident.
    
  • Eggs can be obtained rarely from volcanic debris.
    
  • Has the 'Belly Drum' ability, which causes rapid health regeneration. This can be manually enabled for tame ogrim.
• New animal - Ashland toxbug:
  
  • A new pollution animal found in various ashland biomes.
• New plant - Kwamacap tree:
  
  • A new cave plant that can be found growing in caves in certain ashland biomes.

• New plant - Highland netch shield tree:
  
  • It's a netch shield tree but blue/green.
• New plant - Ashen heather:
  
  • It's just a new flower.
• New plant - Ashen jazbay:
  
  • A new crop plant, the tasty berries can be fermented into jazbay wine.
• New drug - Jazbay wine:
  
  • A wine made from fermenting ashen jazbay grapes. Consumption helps one forget about their troubles, but makes them grow tired faster.
• New volcanic condition - Psychic eruption:
  
  • Recent volcanic activity has awoken an ancient machine. Once slumbering deep within the bowels of the volcano, its screams can be heard echoing in the minds of those nearby. Anyone nearby will slowly be driven to insanity.
