Achievement Guide

This guide lists all the achievement for [How a Retired Strategist Saved the Country] and a few notes on how to achieve them.

A. Unmissable Achievements

These achievements can be obtained by playing and clearing the story. The descriptions are self-explanatory.

Clear stage 1

4. Friend of the Beastmen

6. Do You Like Swords?

9. And Then We Had Peace

Clear story mode

B. Gameplay Achievements

Most of these achievements can only be cleared by using specific builds.

10. Forest Wise Man

Have at least 20 Sages during a battle



The cost of Sages increases per 5 units recruited (and capped at 750 Food and 750 Wood), amounting to 11250 Food and 11250 Wood for 20 Sages. Just remember to invest enough skill points to exceed the count limit.

11. Steel Scrum

Have at least 100 Steel Gear Soldiers during a battle



The total cost is 16000 Food, 2000 Steel, as well as enough housing for everyone.

12. Magic Researcher

Use magic research to strengthen your Magicians to +35

13. Fortress City

Have at least 3,000 Defense from Forts alone



With the Defense of Forts x1.5 researched, build Forts with an accumulative level of 100. You will need at least 4 Forts via Fort Authorizations.

14. Rain of Arrows

Raise your First Strike to at least 10,000



Requires approximately 300 Archers or 138 Falconet Cannons. The actual number may vary.

15. Mega-Nation

Have at least 100,000 Military during a battle



One way to achieve this is by recruiting 500-700 Steel Gear Soldiers and researching Military of Steel Gear Soldiers x1.5 and Military of all soldiers x1.2. I recommend using Final battle preparations during the final defense to boost your Population.

16. Unscathed

Reach year 3 without losing any soldiers



Increase your Defense and First Strike by using Forts and/or Archers to prevent any casualties until you reach Day 0 Year 3. This can be cleared on Stage 2 (Beastmen).

17. Tons of Tea

Produce 10,000 Tea during a single battle

C. Challenging Achievements

These achievements will be especially challenging for those who don't play much strategy games.

C-1. Difficulty B

18. Phenomenal Strategist

Clear the game on Difficulty B without carrying over battle points or using the otherworldly castle



Note: Just to be safe, DO NOT enter any free battles during your playthrough.

21. Master of the Sword

Clear a Free Battle with seed ”569216014”, skill points,set to 26, enemy strength 400%, Combat length: Long, Iron Workshop Lv4, and no otherworldly castle





My recommended Iron Workshop Lv.4 build is to take Improved Mine Lv.2 and Mobile Fort Lv.1 from the Fortress City skill tree. This is mainly to increase the Military of Falconet Cannons. Investing 1 SP for extra Research and 3 SP for Wood Production Up will help speed things up in the starting phase.

22. Harnesser of Forest Power

Clear a Free Battle with seed ”569216014”, skill points,set to 26, enemy strength 400%, Combat length: Long, Forest Sage Lv4, and no otherworldly castle

Optima's build recommendation from the comment section:

Adventurer's Guild: +3 Food, +3 Temple, and +1 Territory Expansion. Focused on Wood Gear Soldiers. 3 Ward Raiders are used to ignore the first few waves but otherwise Tea is not used. Produce Steel from Temples instead of Forges and only when needed. Most buildings should only stay at level 15/40 or 35/40 (and Temples 15/60 or 45/60)

Clear a Free Battle with seed ”569216014”, skill points,set to 26, enemy strength 400%, Combat length: Long, Magic Laboratory Lv4, and no otherworldly castle

Fortress City: +3 Stone, +1 Research, +2 Improved Mine, and +1 Mobile Fort. Focused on Mobile Forts, exploiting the (1.15)^3 Stone multiplier and using Magic Lab upgrades to enhance the economy.

@Aoitenshi
Thanks for reminding, it save me...... maybe a half?
Almost forget there is difficulty selection at the story beginning.
It is totally suffering and wast time to challenge on "simulated battles" for Difficulty B/C achievements.


I hate myself lol

[Aoitenshi]

@brianhong2
1) You need to complete the story mode on difficulty B (or C) to the end. The only thing that you can't do is to grind levels from the free battle. It's okay to use your skill points (in fact, it'd be impossible if you don't).
2) No idea.

[brianhong2]

@Aoitenshi, Hi
I play Difficulty B & C from title menu but get nothing......
The setting is completely default, no manual adjust on skill point, 100% enemy strength.

Wondering where should I challenging for those achievement:
1)Where should it taken for Difficulty B & C achievement? In story mode?
2)Could "Free Battle 569216014" achievement acquired in story mode? Or it just for title's Free Battle?

[Aoitenshi]

@brianhong2 If you're referring to the Free Battle "569216014" achievement, then you should play it from the title menu.

For some stages, it is recommended to send soldiers on a suicide mission (i.e. using 20 military to fight 20 military). This lets you acquire a new land immediately while also keeping 0 upkeep for soldiers. The land and materials for the fort can also be used for more upgrades instead.

[brianhong2]

Ouch...its very tight situation for both difficulty's stage 1B & 1C
I get no skill points to fight against my enemy......
they advance too quickly to stop by bunker, Forts can hold them back until 8th wave.

Can kindly give me some hints?

l play from the title's free battle, should I win those stages under main story mode?

[Aoitenshi]

@brianhong2 Yes, you need to win all 7 stages.

[brianhong2]

About difficulty B and C, It seems there are 7 separated stages , that being the same topic to main story.
Should I complete all 7 stages to win those challenging achievements ?

[Oopsie Poopsie]

Optima life saver man/ i;ve been trying to do the forest power and for the life of me could not get past Year 7 without losing 80% of my army.

[Optima]

Thank you for this guide. I followed your setup and got the Master of the Sword achievement, and now that I have finally cracked the other 4 challenges, I think I should share the outlines of my strategies back.

Master of Magic
- Fortress City: +3 Stone, +1 Research, +2 Improved Mine, and +1 Mobile Fort

Builder of a Fortress Nation:
- Magic Guild: +3 Stone, +3 Power of Stone, and +1 Magic Lab

These two are focused on Mobile Forts, exploiting the (1.15)^3 Stone multiplier and using Magic Lab upgrades to enhance the economy.


Harnesser of Forest Power
- Adventurer's Guild: +3 Food, +3 Temple, and +1 Territory Expansion

Pioneer of New Lands
- Forest Ranger: +3 Wood, +3 Archers, and +1 Forest Sage

These two are focused on Wood Gear Soldiers. 3 Ward Raiders are used to ignore the first few waves but otherwise Tea is not used. Produce Steel from Temples instead of Forges and only when needed. Most buildings should only stay at level 15/40 or 35/40 (and Temples 15/60 or 45/60)

[Aoitenshi]

You might want to tick the "display more information" if you haven't already. The short description was almost useless, but the expanded help was quite useful.

I wanted to master all 5 builds before making a more detailed strategy guide, but in the end Iron Workshop was the only buuld I could use...
