The following Achievement Flowchart was inspired by Ohara's Guide of Paths. This flowchart is focused on listing collectibles, recruits, and achievements as they appear in the various paths/chapters. It lists all the Cats, Information, and Notes available. I hope this ends up being helpful in case some of you may want to map out your subsequent playthroughs to greater effect. NOTE: The Cat in Telliore is listed as Cat #10 because I got it on my 2nd playthrough.

The image below is pretty big. I suggest opening it on another tab.

Aside from battles related to each ending, all other Mock Battles can be obtained via story progression (NG+ included).

• Roland's Ending - Under the Iron Gate
  
• Benedict's Ending - A Long Trek
  
• Frederica's Ending - Before the Goddess
  
• Golden Route - The Assassins

Completing all of that plus the 4 ending-related unlocked battles in the same playthrough will earn you Tavern Regular.
Giovanna is an amazing unit to use in The Assassins mock battle. Gaia's Roar can take out enemies from across the map. Consider using Corentin as well to freeze an entire corner and halt the enemy's advance.

Convictions fall under 3 different categories in this game: Morality (Green), Utility (Yellow), and Liberty (Red). Each one has values assigned to them that increase based on the choices that you make and are therefore a reflection of Serenoa's personal convictions. Unfortunately, you won't be able to view these values until you unlock the Encampment in NG+. Having high conviction values makes it easier to influence your party members to vote a certain way. There are 4 achievements related to reaching 5,000 points in all categories. If you are thorough during the exploration phases, selecting all paths, and buying/selling items. You can have close to 5,000 points in every category by the end of your 4th playthrough. From my experience, it's ok to have Morality a little bit ahead of the other 2 because it's easy to raise Utility and Liberty through farming coins, spending it, and selling items.

Voting through the Scales of Conviction is a House Wolffort tradition. At several points in the game, you'll have multiple paths presented to you. You'll then enter a voting phase to decide which path to take. You can influence your party's decisions using collected information and/or through strong convictions (see above). The higher your conviction scores, the better your chances of convincing someone to vote the way you want them to. Unfortunately, you can't measure these values until NG+. There are 3 achievements related to the voting phases.

Both Unanimous and Tiebreaker gradually become easier to do in subsequent NG+ runs since you carry over conviction values. This means influencing someone also becomes easier unless you pick the least persuasive answer which leads to indifference towards your plans.

Tiebreaker can be done during 3-way votes. With 7 members voting, you can influence your party to vote 3 members each between 2 options. You'll then be the designated tiebreaker.

There are 3 categories of recruits:

• Main Cast
  
• Path-related (Mutually Exclusive)
  
• Shared Conviction

The Main Cast becomes available within the first 2 chapters.

1. Serenoa
   
2. Benedict
   
3. Frederica
   
4. Geela
   
5. Erador
   
6. Anna
   
7. Roland
   
8. Hughette

Path-related recruits are mutually exclusive and join automatically based on which paths you take as the story progresses.

• Rudolph - CH3 visit Aesfrost
  
• Corentin - CH3 visit Hyzante
  
• Milo - CH15 Return to Wolffort
  (Recommend on Golden Route run)
  
• Cordelia - CH 15 Stay in Glenbrook
  
• Trish - CH 15 Check on Roselle
  (if you chose Defend in CH11)
  
• Travis - CH 15 Check on Roselle
  (if you chose Deliver in CH11)
  
• Avlora - CH17 Golden Route

Conviction recruits will join through character stories becoming available as you reach specified conviction values. The table below is sorted by Morality, Utility, and Liberty respectively. NOTE: Maxwell's character story appears in Chapter 15 if you have sufficient conviction values.



After recruiting all units across multiple playthroughs, you'll get:

Serenoa included, there are 30 achievements for reaching the "Pinnacle of Strength" for all units. This involves promoting everyone to Elite and unlocking their 3rd tier of weapon upgrades (no need to buy the actual upgrades yet). Azure Crystal is the only weapon upgrade material that cannot be purchased from the Sundry Shop. 2 copies can be looted from Exploration phases and you also have a chance to receive them from story battle spoils.

Buying all the weapon upgrades for every character gets you Smithy Regular. To help with this achievement, see the Optional Coin/Kudos Farm section below. Additionally, you can sell excess class promotion materials from drops and the Sundry Shop to Lionel once you've promoted everyone and purchased all Quietus points and skills already.

You can get close to enough Coins for all upgrades on your 4th playthrough. If you need more coins now for weapon upgrades, you can farm Conquer the Arena with Lionel, Quahuag, and Narve. Lionel generates money when picking up spoils, Narve's Whirlwind has a really long range, and Quahuag can move Lionel on top of spoils. While Quahuag isn't essential, having him makes things faster as Lionel is a slow unit. Using Quietus skills such as Lightwave, In Tandem, and Missed Opportunity also speeds things up. See the video below for reference.

At 1,000,000 Coins:





Just like with Coins and depending on your playstyle, you can get close to all the Kudos required to buy all Notes, Class Promotion Materials, and Quietus Points/Skills. If you need more Kudos now, you can farm Pincer Attack using Piccoletta and a healer by repeatedly using Ball Toss as a high-ground back attack while on an elevated step for 2 kudos per turn. At 1,000 Kudos:

Quietus are special skills that can quickly turn the tide of battle in Triangle Strategy. They're in the same category as the Chariot system in Tactics Ogre Reborn. To use Quietus Skills, you need access to the Sundry Shop which becomes available around Chapter 5. You'll need somewhere in the ballpark of 1,600~2,000 Kudos for all your Quietus purchases including the occasional Medal/upgrade material purchase. After buying all Quietus skills and the 3 expansion points:

Character Stories add context to the various playable characters. There are 29 achievements (1 for each character) related to these stories. Characters obtained via story progression only have 2 side stories. Characters recruited through Conviction points will have 3 (1 to join + 2 side stories).

To unlock all of a character's stories, you need to deploy said character 10 times in total. The first one unlocks at 5 deployments. Avlora's stories can be unlocked in the same run (Golden Route). You'll have to wait until all regiments recombine to see the prompt and view them.

There are 20 combat-related achievements.

The best way to get Playing with Lightning is by buying a lot of Thunderstones/Large Thunderstones and spamming it during the Avlora Glenbrook battle (Chapter 14 - Vengeance Burns Within Me) and the Kamsell Source battle while pursuing the Frederica Ending (Chapter 19 - Hold Fast to Courage) and the Golden Route (Chapter 18 - For Freedom)

As for Fire and Ice, just check on the top right of your screen if a tile is Flammable/Freezable. Typically there are a lot more Freezable tiles than there are Flammable ones.

To generate puddles for Playing with Water, keep deploying Frederica and Corentin together. Keep casting Scorch/Sunfall on any tile that Corentin freezes. Even easier, you can keep spamming Ezana's Rite of Rain to create random puddles.

There are 4 characters that can counter effectively. Serenoa, Erador, Groma, and Frederica. Serenoa and Erador are self-explanatory. Groma uses Cross Counter when dodging an attack so equip her with Evasion gear and buff her with Cordelia's Elude. Frederica's Flame Shield is a perfect complement to Erador since it counters every melee attack with a Fire attack. Cast it on Erador and Provoke the enemy to get this done real quick.
If your units with pushing skills get too strong, it may get more tedious to complete From Above since the achievement counter won't go up if the enemy dies before fall damage is applied. To solve this minor dilemma, use Jens' Spring Trap.
Only Mental Mock Battles seem to raise up the counter for Veteran Warrior.
Minecarts for Careful! become available during Chapter 16 - Sleep, My Friend, and a couple of Mental Mock Battles.
There are lots of ways to defeat 5 enemies simultaneously. Narve is probably one of your earliest and best bets with his huge range that expands even his Whirlwind. See the Optional Coin/Kudos Farm section above for an example.
The rest are extremely easy and will come naturally:

1. Few but Fierce
   
2. Supporter
   
3. Enfeebling Force
   
4. Working Together
   
5. From Behind
   
6. Healer
   
7. Item User
   
8. Spoils of War
   
9. Forces Collide
   
10. Efficiency is Key
    
11. Shrewd Strategist

The following 10 achievements are related to picking specific paths in the story:


In Chapter 9, you'll come across mutually exclusive paths leading to 2 different achievements. If you travel to Hyzante and report Sorsley successfully you will obtain Wrongdoing Exposed. To achieve this, complete the following steps during the Exploration phase:

1. Talk to the citizen with a green turban near your starting point.
   
2. Talk to the girl inside the top left house.
   
3. Talk to Clarus outside (top left corner).
   
4. Talk to the Rebel in Blue (West corner)
   
5. Talk to the Soldier guarding the Rebel's house
   • Answer "I did see someone rather suspicious"
6. Speak to the Rebel in Blue again
   
7. End the exploration phase and answer the following:
   • "He sold illicit salt"
     
   • "He kept a secret ledger"
     
   • "Sorsley's encampment"

If done correctly, the chapter title when saving should be The Carelessness of Men and you will battle Sorsley at his encampment. NOTE: Failing to report him counts as another path.
If you choose to transport Sorsley's Illicit Salt, you'll have the option to reveal Roland's identity to Svarog later in the chapter. If you choose to reveal his identity, you'll obtain The Enemy of an Enemy and gain his trust.

NOTE: If you are minimizing the number of playthroughs required for the 100%, it's recommended that you leave the option to reveal Roland's identity until you do the Golden Route (Serenoa's Ending). Revealing Roland's identity is one of the requirements to reach the Golden Route ending.


In Chapter 15, you'll have three options on how to proceed. Each path leads to chapter/choice-specific recruit. Going to Wolffort gives you the Birthright achievement.

• Wolffort = Milo
  
• Glenbrook = Cordelia
  
• Rosellan Village = Trish/Travis depending on CH11 choice

NOTE: Just like revealing Roland's identity to Svarog, it is recommended that you leave the Wolffort path for last because it is one of the requirements to reach the Golden Route ending.
Just like before, you'll have three options to proceed in Chapter 17. This time around, each choice has a specific achievement. Having high conviction values will help you pick out a specific ending, but overall it's not a big deal. Frederica's vision is related to MORALITY. Roland's stand is related to UTILITY. Lastly, Benedict's strategy is related to LIBERTY.
Of course, after much suffering associated with the 3 endings above, we finally arrive at our reward—the Golden Route. This is considered Serenoa's Ending and the True Ending, but rather than a True Ending I treat it more as a reward for all the pain endured in previous runs.

To reach the Golden Route, you need to:

1. CH7 - Surrender OR Defend Roland
   • If Defending: Don't trigger any Wildfire Traps
   
2. CH9 - Transport Salt
   • then in CH10 - Reveal Roland's Identity
3. CH1 - Defend Roselle
   • then in CH12 - Find the Key
     • Talk to Elder in his home
       
     • Talk to Benedict
       
     • Talk to Frederica
       
     • Enter the Elder's home and inspect the now vacant rug.
       
     • End exploration and present the rock.
   
   
   Secret of the Continent Find the key in the Rosellan village.
4. CH15 - Return to Wolffort

If done correctly, instead of going to a vote in Chapter 17, Serenoa will enter a monologue in an attempt to find another path forward. Answer the following to lock in the Golden Route:

• Greet them with the Wolffort demesne's wildfire?
  
• Might Lord Svarog be the key?
  
• We can expose the truth hidden within the statue.
  
• They're of the Consortium.

NOTE: I recommend leaving this for your final playthrough because it allows for the use of 30 units divided into 3 regiments. The 3 regiments will recombine once you complete their respective battles. After completing this route, pat yourself on the back for an emotional journey and a brand new title screen (complete with awesome music)!
