This Biome is currently relegated to the status of sub-biome. It no longer appears as its own planet type.
Ugly trees, questionable puddles of blood and occasionally deadly weather all combine to made this a weird place to visit. Some were once home to life forms much like us... until their experiments wiped them out, leaving behind only gory grossness. Which explained the trees that stared at you. Good times.
Codex description Edit
When wandering a bloodstone world, you'll be reminded of blood an awful lot. Because, y'know...blood pools everywhere. And really messed up looking trees. They are a great way to stock up on several sorts of materials through extraction, though.
You could have encountered these subbiomes on Bloodstone worlds: Hive, Alien Forest, Sulphuric Magma, Cellular Expanse, Red Waste, Rainbow Wood, Blood Gulch, Hell Hive, Eldritch Field, Eldritch Forest, Dry Riverbed, Deadwood, Magma, Savannah, Volcanic
Now however, Bloodstone itself is a sub-biome, encountered at random on certain worlds.
Removal/Sub-Biome Relegation. Edit
Bloodstone is no longer in planet circulation. This is due to it being too similar to Atropus worlds. Bloodstone mini-biomes can still be found in circulation however. You may also find an Unknown world which has a Bloodstone biome as its primary surface biome.
