What level do my Iron Storages need to be at to upgrade to Stronghold 21?
How many of each building are available?
What is the Hunter’s Lodge?
This new building allows crafting Titan Battle Items, most of which are produced using the new Titan Parts that Titans will drop in loot when a sufficient number of Giant Harpoons are used on the Titan by your alliance.
The Giant Harpoon itself is crafted using conventional Crafting Ingredients — 5x Common Herbs, 1x Large Bone, and 1x Clean Cotton.
@Mariamne’s fantastic and beautiful guide to Titan Battle Items in the Hunter’s Lodge:
What level building can be converted to a Hunter’s Lodge?
The Hunter’s Lodge feature becomes available once your Stronghold has been upgraded to level 21. Once the Stronghold has been upgraded, you can start converting a building that is over level 5 and offers you the option to ‘convert’ to the Hunter’s Lodge. Mines, Farms, Training Camps or Forges can be converted into the Lodge.
What Level Food Storages are required for Research of Giant Harpoons?
The Research for Giant Harpoons is 2771k, which requires all Food Storage to Level 20, and one converted to an Advanced Food Storage.
Food Storage Calculation:
10k for Stronghold + 689k for Level 20 * 4 = 2766k
10k for Stronghold + 689k for Level 20 * 3 + 708k for Advanced Level 1 = 2785k.
Do my Iron Storage, Food Storage, Mine, Farm, and House need to be at Level 20 to convert to an Advanced version?
Yes, each of the Iron Storage, Food Storage, Mine, Farm, and House need to be Level 20 in order to be converted to their respective Advanced Building version.
Do I need to upgrade my Stronghold past Level 21 in order to continue upgrading the new Advanced Buildings?
No, each of the new Advanced Buildings can be fully maxed without further upgrades to the Stronghold.
Additional buildings unlock at Stronghold Levels 23 and 25, however. (See How many of each building are available? for more on that.)
What are the Titan Battle Items? What do they do?
How does the Giant Harpoon work?
The Giant Harpoon is a battle item crafted in the Hunter’s Lodge.
When enough Giant Harpoons are used on a Titan, it will cause Titan Parts to be dropped, even if the Titan escapes. The level of the Titan will determine the minimum number of Harpoons needed to guarantee a Titan Part drop.
The more Giant Harpoons an Alliance uses on the Titan, the better the drop rate of Titan Parts. The amount of Titan Parts dropped are based on the players’ Loot Tier.
How many Giant Harpoons can I take into battle? Where can I use them?
You can take up to 5 Giant Harpoons at once. They occupy a Battle Item Slot, like any other Battle Item does.
Giant Harpoons can be used for Titans as well as Quests and regular World Map Stages.
Because they’re considered a 4* Item, they can also be used in Challenge Events — but only on the Legendary Stages.
How many Giant Harpoon hits are needed on a Titan for it to drop Titan Parts?

What’s special about Advanced Houses?
They make Recruits!
Much like a Farm, Mine, or your Watchtower, the Advanced House produces Recruits on an hourly basis. This expands its functionality beyond just being storage for Recruits you earn through playing Stages and winning Raids.
Will the Raid Reroll cost increase when I upgrade to Stronghold 21?
Yes. Raid Rerolls cost 100 Food per Stronghold Level. Upgrading to Stronghold 21 will increase the cost to 2100 Food instead of the 2000 Food cost when you have Stronghold 20.
