I wanted to post of pictures of the grinders on SDF-MC.
Creeper Grinder (this one may need some work, not generating as many as expected)
Guardian Grinder (This is pretty brutal. Plenty of food there but have diamond or netherite armor with mending)
Loot Chests at the Guardian Grinder
Slime Grinder
Warp Room (This is a warp room at the Guardian Grinder that has warp buttons to all grinders (Save on warp slots)
Triple Cave Spider Grindere
Magma Cube Grinder
Enderman Grinder
