Ultimate Hard Core

That might be it, but I don't remember.
map changes(added wool in one of the places). (learn how to install below.)
place -10 max health shields in the crafting table, you can delete it now.
New tool! Desmelter! place 8 red stone like the emerald furnace into the crafting table. It will tell you it has been created. Or check, it might be there.
Desmelt cooked meat(Cooked Pork-chop, Cooked Fish, Cooked Salmon, etc.)
Added ! as a texture to the uhc11 paper renaming.

Installing the map changes:
rename a piece of paper to uhc11 or uhc12, or uhc13, I think you get it. It should show a exclamation mark. Put it in the middle of the uhc crafting table. It should tell you it's been completed.
