DISCLAIMER:
THE MOST ACCURATED PACK IS THE 1.18'S ONE, IF YOU PREFER THE INACCURATED CHANGES YOU CAN USE ANOTHER ONE OF A LOWER VERSION (IT REALLY DOESN'T MATTER, MINECRAFT WONT CRASH) OR ASK ME TO INCLUDE THAT CHANGES (DON'T BE SHY 😉)
Changes:
-Non hardcore mod's hearts are now hardcore-like
-Armor hearts (no longer in 1.18 and on, if you dont like the removal please notify me)
-Saddle hearts
Withered Hardcore Hearts (terran_game): Is a texture pack that swaps the hardcore hearts for the withered ones
