Probably not useful on its own, mainly adds new blocks and other stuff to the Serious Remnants pack.
Current features:
Water blocks are finite except for in the deep ocean biome
Lava blocks in the nether regenerate
New bed mechanics, can only sleep later at night and sleeping consumes hunger/saturation and applies weakness
Blocks can be affected by gravity and fracture (1.11.2 only, 1.12.2 version has its own mod "Fragile Blocks")
Adventure Block - block that puts users into adventure mode when they are within range (and back to survival when they move away). Can only be placed and edited in creative mode (1.11.2 only)
Cosmetic Beacon - Beacon like effect that can be dyed (right now only useable in creative mode) (1.11.2 only)
Killing cows with an axe will always drop leather but no beef (better quality axe = more leather)
Enchantment Table use is disabled
Tough as Nails compatibility: Bottles and canteens consume water source blocks
Embers + Survivalist compatibility: Survivalist Rock Ores give 6 nuggets worth when using the embers smelter (1.11.2 only)
Most features can be changed using the config file.
