// For a list of lvls to farm, check this guide.
This guide is based on my personal experience and data that I myself collected (link below). I am aware that supposedly there’s other people working on that as well, and I don’t mean to overstep, but I’m not the type that waits for things to happen and I decided to do it myself. I’m sharing here my findings. One last thing, English is not my first language, so please ignore my misspellings and bad grammar.
Which levels to farm
Skipping to the list and I’ll explain why these lvls and not any other below:
Best Level to Farm for…
Any color monsters: 8-7
Blue monsters: 8-7
Green monsters: 7-5
Yellow monsters: 10-6 or 12-9
Purple monsters: 7-4 or 8-4
Red monsters: 6-8, 11-6 or 20-4
Best levels to farm XP, Iron and Food, again you’ll find the explanation below. You must farm the highest level below, but that is doable without using items or a possible death:
3 Energy: 1-1 to 7-4, 7-7 to 8-1, 8-4, 8-6 to 9-1
4 Energy: 11-1, 11-2, 11-5 to 12-9
5 Energy: 16-8 to 17-1
6 Energy: 19-9 to 20-4
7 Energy: 22-1 to 22-9, 23-8 to 23-11
*XP levels not yet complete.
*Quests are excluded from this, but there’s quest lvls that are better to farm Red colors, for example. Also working on including them.

About the monster, items and recruits farming.
The above list was made to be the most efficient lvl, taking in consideration the follow in that order of priority:
- Farm Goal
- Energy Ratio
So, the blue one must be 8-7 because:
- It can spawn anywhere between 9-15 blue monsters. 9 being the higher minimum and 15 the higher maximum in all other levels.
- Has a 3-5 monster chance per energy, also higher ratio available.
- The highest XP, about 40+ than other possible options.
Same goes for the Green one, but with different amounts.
Yellow and purple have 2 options for two different approaches:
- Levels 8-4 and 10-6 have both a solid 11 monsters per lvl*. Levels 7-4 and 12-9 have a range of 9-15 monsters per lvl. In theory, the first 2 are a safer bet, but the last 2, with luck, can be more efficient. [*Still trying to figure out if these levels can spawn waves of 4 mini-bosses, if yes, the numbers would change to 11-14, but even so they are absurdly rare.]
- Both options have equal costs, both purple costs 3 energy each, both yellows 4 energies each.
- If you accept that both approaches are equal, you may chose between them based on XP. 8-4 and 12-9 are the ones with higher XP.
The red case is a difficult one. There is no low level with a guarantee number of red enemies. The best levels to efficiently farm it is the 20-4, it has the best energy/monster ratio and best XP between the possible options. Even though it costs 6 energies, it guaranties almost 2 enemies per energy.
The low level alternative is the 6-8 (a red-blue level), that has a chance to spawn between 0-15 red enemies. In theory, the results of farming this 3 energy level can be far superior of the 6 energy one, but in reality you can just as easily end up with waves filled with blue enemies.
Another low alternative is 11-6, one energy more expensive (uses 4 energies), but gives you a 2 guarantee boss with the same 9-15 yellow-red waves that can spawn anywhere from 0 to 15 enemies.
If you cannot easily farm 20-4 (or other similar levels, such as 19-4 and 19-6, that have same monster/energy, but gives less XP), your best bet is 6-8. Or if you are lucky, you got quests full of fire enemies.
Any monster case – that’s the highest monster/energy and higher XP available.
About the items and recruits. Contrary to all other resources that increases steadily with the difficulty (such as XP, iron and food), items and recruits are based on total amount of enemies, the difficulty of the level will then reflect on the quality of those items. So in order to farm recruits you will have to play the higher enemy/energy available, which is 8-7.
If you looking for generic low items that can drop in any level (such as practice sword and adventurer’s kit), 8-7 is also the way to go. If you looking for a specific item that drops in a specific province, you’ll have to find levels with 4 waves (that will have a 11-17 monsters per lvl). It’s not clear, although, how the difficulty (inside the Province) may interfere with the chance to get that item, so I suggest farming the highest 4 wave lvl you find (not only because of that, but also for the higher XP and other resources).
I also found that troops and heroes drops are completely random, although it is very clear that the level difficulty will interfere with the number of stars available.
About the XP, food and Iron farming.
In the above, monsters and items (including recruits) have the same average on all levels, so the harder the levels get, more energy they cost and the monsters/energy ratio start to drop considerable. So while 8-7 is 3,6-5,6 monsters per energy, 16-9 is 2,2-3,4. That’s why there’s only one or two specific levels for you to farm, no matter what is you power and progression in the campaign.
XP, food and Iron is a different matter, they steadily increase as you progress and what level you should farm is directly related to your campaign progression and currently capabilities. That’s why there’s not a single level, but a lot of them.
Anyway, because of the abrupt change in energy cost, the XP/energy (same for iron and food) abruptly change as well, dropping a lot. For example, 9-1 will grant you 285,6 XP per energy; the next one, 9-2, only rewards 214,25. If we were to make a graph it would look like a steady increase all the way to a peak, followed by an abrupt decline (caused by the change of energy cost), that would then increase again steadily, surpassing the first peak until it reaches a second one, and so on. In total there are 5 peaks, and 4 abrupt declines. Below a graph I made in my mobile, so give it a break (haha), to represent how it would look like. (I might actually do one for real, after I complete the sheet.)
So the list is basically that graph with the abrupt declines and catching up all cut out:
1-1 to 7-4, 7-7 to 8-1, 8-4, 8-6 to 9-1 – First Peak, cut out declined until it’s a higher XP/energy – 11-1, 11-2, 11-5 to 12-9 – Second Peak, same – 16-8 to 17-1 – Third Peak, same – 19-9 to 20-4 – Forth Peak, same – 22-1 to 22-9, 23-8 to 23-11 – Fifth Peak and end.
It’s important to point out that there’s a few hiccups here and there, for example, 8-1 rewards 747 XP, 8-2 to 8-4 gives 757, 8-5 drops back to 747 and 8-6 increases again to 807. The graph would not look like a clear line, but because I’m yet to complete the sheet, it doesn’t consider all those hiccups (working on that). I do suggest though, if that’s important to you and you really want the best efficient one, check the data and XP of the levels and compare it to the lvl you considering before deciding which one to farm. Also consider items that you have interest in farming.
The food and iron follow the same logic, and have a similar graph, but the reward is not a fix number, so there’s a variation dictated by luck. Taking that into consideration, the best levels to farm them are pretty much the same as the ones for XP above. In other words, the best way to farm food and iron is too farm XP.
Any questions, just ask.
Here is my current data: https://docs.google.com/spreadsheets/d/1UnPFObu5XJkLJVjxcgoia-0sHlO0qHw9UkrPh5i_ZXU
Please take in consideration that items, recruits, iron, food and waves composition and formation will vary. XP, energy cost and boss wave are the only fixed values.
Last, I’m very methodical, and I save printscreens of everything so to be sure of my results. Because of that I won’t open the sheet to public edition, nor add any information given in the comments without verifying myself. I mean no disrespect nor to imply anything, I’m just really methodical. That being said, I’ll add any and all data from printscreens.
I hope this can be useful.
