Here's what I've learned to work for me, but please critique and offer better suggestions/improvements. What I've been doing is trying to pair mats as much as possible. For example, with my Persians my main civ (doesn't matter which, but your first lvl40) I paired Construction with Engineering. Why? I noticed that in Argos I can buy the recipe for the Blue consumables, so Bandit Tower and Stone Deposit respectively. Both of those blue plans need 74 Stone Blocks but different secondary ingredients of 24. Bandit Tower needs 24 Bronze Ingots. Meanwhile, Special Ability: Quarry Pit (Stone Deposit) requires 24 Oak Planks instead. Yet, they still share the 74 Stone Blocks as the "primary" ingredient! So then on just the first primary/main lvl40 1 civ, my workshop compsition of 8 allowable workshops is the following: 2 Smelter Workshops producing Bronze Ingots every 30 minutes 6 Mason workshops producing Stone Blocks every 15 minutes 74 Stone Blocks to 24 Bronze Ingots is 3x, so I figured that for every 1 Smelter workshop producing Bronze Ingots, I needed 3 Mason workshops. However, later I realized that I didn't figure in the speed, so the difference of 30 minutes vs. 15 minutes, basically halves it. I'm now getting away with just 4 Stone Mason Workshops. This frees me up to have 2 workshops on Logger Workshop producing Oak Planks. Thus, with just one civ, I'm ensuring a steady supply of the two Blue consumables for my main civ and all other civs I'll level. Already, I have 5 Bandit Towers and 5 Stone Mines for my main civ and 5 more Bandit Towers and 5 more Stone Mines sitting in my Empire Vault for any of my OTHER leveling civs to use for tough missions. Another good combo like the above is Religion + Infantry because Religion's Golden Deposit shares the same primary ingredient of 74 Animal Hides with the Infantry's Bandit Spearmen, only the secondary ingredient of 24 Bronze Ingots for Religion's Golden Deposit is different from the 24 Olive Oild for Infantry's Bandit Spearmen. Regarding workshops, I've set up the same way as above: 2 Smelter Workshops producing Bronze Ingots every 30 minutes (towards Religion's Golden Deposit consumable) 4 Skinner Workshops producing Animal Hides every 15 minutes (primary ingredients towards both!) 2 Farmer Workshops producing Olive Oil every 30 minutes (towards Infantry's Bandit Spearmen). I did this on my Babylonians. Third, I found a lot of recipes overlap somewhat, but not as neatly between Metalworking and Archery, so obviously Celts. Metalworking CRAFT's Mercenary Headhunters green costs 74 Animal Hides and 36 Pine Planks (so any overfill from Babylonians not needing anymore Animal Hides or Pine Planks goes to Celts). The above green Metalworking recipe has a nice synergy with Archery's blue Mercenary Bandit Archers which costs 74 Pine Panks and 24 Leather. Thus there is overlap on those Pine Planks! Yeah, the leather can always just be bought in a pinch. Plus, just today I got real lucky with a drop of "Dark-Flight Arrows" so I can't wait to lvl up Celts first, before my Greeks or Egyptians. Mainly because I have sooo many Metalworking recipes and now an Archery recipe that I hope will become a money maker for me on the Trade Channel. I stuck Craftsmen (blue Cow deposit) and Cavalry (blue Bandit Cavalry) on my Norse. Also, I got lucky with a drop of Blue Fire Ships, so actually my Norse is producing three blue consumables for himself and all the other civs! I don't really need now Greeks or Egyptians for my crafting... probably to fill the gaps, like in Leather and specialty goods. Two of my civs are pumping out Work Tools. I'm not sure about Gemcutter, Schrivener, so far I don't see which of my currently available recipes that would satisfy. How and where do I get recipes for Precision Tools, Ebony Planks, the higher-tier stuff? I don't see no store that sells them for Coin or EP? Are those recipes just drops from Treasures/rewards like everything else? What do you guys do for crafting? Does my setup make sense or does not? Please feel free to offer your constructive criticism and please suggest improvements on what I should be doing with my crafting. My goal was to be able to produce self-sufficiently on my own at least the blue recipe consumables from Argos to make leveling easier for my other civs after my MAIN primary Persian one. Cheers!
