[Stronghold 21, Game design] Iron bottle neck- cause and iron farming
Click for background
Emblems and iron
Emblems require clumps of iron. You cannot unlock 1/10 of a class node. I had 6x 4*+14 heroes unlock nodes the same day. This was a huge drain on my iron.
Two builders and food
Stronghold 23 is not being released. You cannot work on several Advanced Buildings Level 2 at the same time like you could with regular buildings.
Before Stronghold 21, when low on iron, but hoards of food, you could work on any of your four regular mines, and the watchtower, all of which used food. But you cannot upgrade your watchtower past level 20 and you can only currently work on one Advanced Mine at a time.
Advanced buildings taking 10 seconds to convert. But take more than 10 seconds of iron production. This is causing a bottle neck for two builders.
Single builders can switch to upgrading Advanced Mine with food while they wait for iron production. One of the times second builder is severely hampered.
5* Battle items
Originally I was going to upgrade Advanced House to Level 9, highest possible with 5x Iron Storage Level 20. This would give me 5 recruits per hour.
But my alliance has decided to use harpoons. Now I need the iron to build Lodge Level 4. This unlocks Titanium shields, and Panacea, the only 5* battle items useful against triple bosses like Sand Empires or Grimforest.
After I unlock Lodge Level 4, I will have to construct at least 1 Harpoon per day. This takes iron.
You can hoard food in training camps. There is no way to hoard iron.
Raiding for iron
The Devs nerfed raiding for iron, and food, ( see notes )
Iron bottle neck
All the above is causing an iron bottle neck for Stronghold 21. This may, or may not, be a deliberate design choice. It may also just be an unintended consequence of the Advanced Building design.
Season 1, province 17, stage 1 ( stage 1.17-1 ) has 1510 iron per WE, but only 1.4 recruits per WE.
Stage 2.15-9N has 1193 iron per WE and 2.857 recruits per WE but I cannot auto play it.
Stage 1.7-7 has double Rugged clothes, but only 1017 iron per WE.
So currently I am alternating between:
Stage 1.12-9 with 1388 iron per WE, 2.5 recruits per WE, and I can auto play with 3* heroes. This has 9 to 11 monsters for 3 WE or 3.33 monsters per WE. It has 1/ 1.5 loot rolls per WE.
Stage 2.6-9N with 1200 iron per WE, 2.5 recruits per WE, and I can auto play with the Wu Kong grinder gang ( see links below ). This has 11 to 17 monsters for 6 WE or 2.33 monsters per WE. It has 1/ 1.5 loot rolls per WE.

Examples of iron farming
From Barry’s helpful data project
( Barry Farmz Here -- Comprehensive data driven farming guide )
1.17-1 = 1510 ( 1.4 recruits)
1.7-7= 1017 ( Rugged clothes)
2.15-9N= 1193 ( 2.857 recruits)
2.6-9N= 1200 ( 2.5 recruits)
1.12-9= 1388 ( 2.5 recruits)
1.9-1= 1350 ( 2.0 recruits)
Wu Kong grinder gang
(Wu Kong grinder gang or Powerful rainbow auto play team or Wu Kong plus 4 healers)
Click for raid nerf
First link caused all food and iron gains to decrease because of the way Elo’s math works. This is especially true if you do not trophy drop.
The second link increased drops for 3*/ 4* ascension items, Epic tokens and Trainer heroes, but nerfed food/ iron from raiding.
Both made the watchtower much more useful, but raid energy flasks much less useful.
