This map is based on the principle of treating the zombies-villager with the golden apples readily available with the spawner of pigman zombies.
Once you've cured 2 zombies, using potions exchanged by the "Starter", you will be able to make a farm, and with the exchange, make a lot of emeralds easily used to go into the nether (starter trade lava and water), to have enchanted armor and weapons.
Moreover, thanks to the librarians you can get enchanted books and, with an iron farm, you can upgrade further.
This is a long map that requires skills of advanced Minecraft.
