    • First, if there is an adjacent container behind, it detects the signal from the container. If not, it detects the signal from redstone components.
    • Then, if it is not less than 15, the detected signal becomes the input signal. Otherwise, it also gets a signal from item frame and container behind separated by a redstone conductor block from the comparator, and take the maximum of the three as the input signal.
Flower pots
  • Has a bottom texture when empty.
Gravel and soul sand
  • Generate in the new soul sand valley biomes.
  • Using bone meal on netherrack adjacent to nylium converts it into nylium.
    • If two nylium blocks of different types are present, it chooses the type at random based on how many blocks of each type are around it.
Nether wart blocks
  • Generate as a part of huge crimson fungi. Sometimes generates in the ground replacing the crimson nylium in crimson forest biome.
