About this Mod

I decided to create this pack to make ancient cities more like a proper city and utilizing new features added since their introduction. It features plenty of new buildings and changes to old ones with inspiration from official mood and concept art!

HOW DO I ACTIVATE THE PORTAL?

Get yourself some echo shards and beat the dragon! The portal takes you to the end but you need to find a stronghold first. There are advancements for both the portal activation item and key item for the vaults and they appear in the crafting book once the correct items have been obtained.
Crafting recipe for the portal activator in the current version.
Once you have the item, simply look into the maw of the portal and right-click while holding it. Then watch the magic happen.

Aside from a visual and spacial makeover it features:

  • PORTAL ACTIVATION! It leads to the End but you need to go there first.
  • Increased size! They're denser like real cities and larger than the vanilla cities.
  • Advancements!
  • Vaults with their own keys!
  • Pots with loot!
  • Archaeology!
  • Banners!
  • Beware certain buildings and mind your digging. You may be less alone down there than you thought.

Loot: Pots, vaults, and suspicious gravel have their own unique loot tables. Chest loot has been tweaked, which includes but is not limited to more pieces of iron armor than leggings and removing 13 and Cat. 

Notes

  • Trial chambers will spawn a little shallower to avoid being cut into by the new cities
  • Lava and waterfalls are more present due to the larger size
