Inspired by how detailed and accurate the TBS Decompiler guides for the previous two games were, I thought a guide of equal quality and details was sorely needed for the third game. Similar to the guides for the earlier two games, the specific location of conversations are included so you can explore the files and confirm my findings for yourself if so inclined. It is possible that I may have missed obscure side paths. If you find a node I missed just let me know and I'll add it in. In the following guide I will BOLD the options that I felt were the "best" but by all means decide for yourself.

A few general tips:

• Renown caps at 1000.
  
• Achievements each give 5 renown, so you should generally aim to complete achievements.
  
• Try to keep your kill counts even across all characters. The kills count requirement for Rank 10 is lowered from 30 down to 24 in TBS 3. From rank 10 onward, every 2 kills = 1 rank and costs only 10 renown per rank. Anything more than 34 kills is wasted.
  
• From a kill count and renown viewpoint increasing the danger stat is a good thing, but it does make fights harder by spawning more and higher level enemies. Increasing the difficulty setting is really the only way to affect this stat in TBS 3.
  
• Battles and wars are good things since they give kills and renown, and if you go for a 2nd wave they also give morale and a chance at items; they also help you towards the "Warmonger" achievement.
  
• Losing a battle is a bad thing; you can lose an achievement and consequences for losing change from event to event, but will not be covered in this guide. If you are about to lose a battle just reload the latest save and try again, and/or reduce the difficulty setting.
  
• The tag “Clansmen Forage” are set points at which the supplies you receive equals num_peasants / 20. Since the amount of supplies you receive depends on how many clansmen you have at the time, you generally want to maximize the number of clansmen you have for the event.

All options lead to the same result. Option 1 gives a little extra dialogue.

16_pop_2_rugga_battle_inside

"Shut up" = nothing
"Break Rugga's nose" = rugga_appearance=1 (Makes Rugga look bloodied. It's the RIGHT choice)

"Any allies are welcome in these times." = peasants+100, fighters+10, supplies+50, day+0.5
Keep your head down, trying to avoid a scene. = morale-5, day+0.1

16_pop_travel_market

Browse the merchant stalls as you go. = Market: 142 supplies @ 2:1)
Leave the trading for later. = nothing

*In the next fight, kill only characters wearing blue outfits to get the "Horseborn Rampage" achievement.

Or forgiven.
All options lead to the same result.

16_pop_5_gudappears
It is trouble. A few yards ahead, you spy one of Petrus' guards face down, an arrow in his head. Petrus curses angrily, and runs ahead just as armed men appear from the crowds, surrounding him and attack his guards. "It would be a tragedy if something happened to him," Rugga taunts.
Join Petrus to repel the attackers! = Battle (with Petrus as an extra fighter)

"We need protection, more men who can hold a sword." = fighters+20
"We need a safe place to rest in Arberrang." = clan_safe_place=3 (overrides clan_safe_place chosen earlier, later prevents any peasants and fighters from dying, saving you at least 57 peasants and 16 fighters)

16_chat_oddleif
=She smiles politely, waiting for your question.=
Option 4 ends conversation early. All other options can be explored. Ultimately gives morale+15.

* An ideal decision later on will cut your supplies in half, but since supplies will be highly limited later on, you may want to buy up all the supplies regardless.

Intimidate the Ravens. = nothing

"Help us and you'll have half our remaining supplies, for your varl. We'll manage with less." = lose half of supplies, Hakon joins (no effect if Hakon is already in party)
Note: even if Hakon stays/joins, all varl and varl heroes (including Hakon) will temporarily leave the party to assist with the plan. They will not be available for the next few fights.

*Avoid visiting "Heroes" landmark at this stage if you can. For some reason each visit incurs day+0.25 at this stage.

"You know what? I don't have time for this. (Leave)" = nothing (you miss out a lot of dialogues, but Rugga's surprise is quite worth it, if you didn't want to get violent with him)

"I'm a man of peace, at heart."
"I'll do it if your men join the fight, instead of giving us trouble." = much later on, peasants-100, morale-10

"No more chances. (Finish Rugga)" = Rugga dies & achievement*
"He's lucky you're here, Oddleif. (Leave)" = nothing
*If Rugga dies, you will mainly miss out one minor event much later on. In all other cases, he is effectively replaced by Josurr (Lundar's mayor) and there is minimal practical impact. As such, you may want to kill him just for the achievement, or keep him alive if you find him to be more interesting of a character than some random old mayor

19_pop_travel_junobolverk
"I will lead Bolverk away," Juno says. Eyvind looks blankly into the distance, as though he already knew what was coming, but Juno continues. "The rest of you will wait for my return within Ridgehorn."
All options lead to the same result.

Folka steps forward. "I don't trust you, and even if I did, you can't handle Bolverk on your own. We split the caravan." She volunteers herself, Oli and Sparr, who give each other dubious looks. Folka adds, "I don't take orders, remember?"

Trust Folka's intuition. = Folka dies
Pull Folka away before something goes wrong. = Folka lives, achievement

From Chapter 20 onwards, you will start earning points in the flag "doomsday_timer". The value of this timer is in days, and represents how long Arberrang can hold while Iver travels in Chapter 21. When the timer runs out, the game would return to Arberrang where the caravan must go through additional events and battles in order to buy more time. Iver will then be able to travel using those additional days. You will be able to return to Arberrang a total number of five times (each time with unique content).

In theory, more days are better. However, each return to Arberrang contains story and events that are entirely missable. If you always make the "best" choices, you may end up returning to Arberrang only once (or not at all even, if your imported save has an overpowered clan), missing out large chunks of story. For that reason, in this guide the best choices in bold are sometimes ones that will help you see more/most of the Arberrang content. Even if you do this, sometimes it still won't be enough, and you may need to waste time resting on Iver in order to return to Arberrang more times.

If you want to minimise your number of returns to Arberrang for achievement purposes, simply choose the options that increases your timer the most, and uses up your timer the least (as Iver). These choices are in italics.

"Oddleif's trying to talk some sense to them now."
All options lead to the same result. If Rugga is alive, Option 2 gives extra dialogues.

20_pop_travel_newhorseborn

"We've had enough trouble with the horseborn, already." = day+0.1
"Are you sure they want that?" = progress
"I don't know, let's talk about this another time." = day+0.1

"We won't know until we ask," Ubin replies. "In times like these I believe it's better to have too many friends, than too few."
Approach the horseborn and offer them protection under your banner. = fighters+23, day+0.2
Have a horseborn ally speak to them on your behalf. = progress
"Maybe we could do this another time." = day+0.1

20_pop_travel_wallrepair
Through still-gaping holes in the splintered walls you glimpse the dredge indolently lurking. Bleary-eyed workers do their best to fill the cracks. The foreman spies you at the head of the caravan; "Got any fighters with strong arms? Gods know we could use 'em, and they'll be well fed."
(If fighters > 10) Give them a token number of volunteer fighters to help patch the walls and stand guard. = fighters-5, morale+5

Promise to do what you can, when you have time. = morale-5

20_pop_travel_scaredkids

Draw weapons and encircle Dytch. = Battle with Dytch as extra fighter
Drag Dytch out of the hole as quickly as possible. = Dytch injured for 2 days
Try to make a distraction away from Dytch. = Battle with Dytch as extra fighter

21a_pop_travel_dizzy

21a_pop_travel_eyeballmonster

Run for it and hope it doesn't notice. = nothing

21a_pop_2_frozen_ocean
"Ice," says Eyvind. "Or, it once was. I can't be sure what the darkness has done to it." Unlike the jagged shale you've tramped so far, it lays in geometric patterns of flat planes, some hanging curiously in the air. Valgard dares a short slide onto it, saying "Seems solid enough."
"Maybe for small folk. Let's skirt the edge." = timer-1.6
Spread out in single file and push onto the ice. = nothing
Rest and prepare better to move across ice. = rest, timer-1

Encourage everyone to toughen up. = morale-5
Ask Eyvind if he can do anything to help. = morale+15

21a_pop_4_godstone_demands
Juno sags upon her staff. She looks at Eyvind, but his stare is leagues from here. "All will be well," she starts, but jerks back from Folka's spear-point/Oli's axe blade at her neck. "No magic tricks," Folka/Oli hisses.
All options lead to the same result.

=She suddenly looks very tired, but tries to smile.=
All options lead to the same result.

21a_pop_6_godstone_bell
At the godstone's center an enormous bell dwarfs the other, smaller chimes hanging throughout. The bell's handle calls to you on a primal level. "Are you thinking of ringing it or kissing it?" Sparr asks. "I wouldn't do either."
Tap the bell with your weapon. = return to same options
Pull hard on the rope hanging beside the bell. = Dredge Clapper (lvl 13 item: +2 AGGRO; Knockback on STR>3; +3 STR Talents; +3 BRK; +3 STR Attack), Battle, unlocks Rest (so that you can waste days here to return to Arberrang)

"Usually I keep that sort of thing to myself, but what's the point?"
"Oli, I think you may be spellweaving..." = progress
"Probably best not to think about it." = nothing

"What a time to be alive, eh varl?"
"I'll drink to that." = morale+15
"Not if it was all for nothing." = nothing

*At this point, you can waste days by Resting at the Dredge Godstone. You will need at least 5 days to reach your destination. The maximum number of additional days you can get from Arberrang visits are the following:
First Return: 9 days (+2 days if Ruin wasn't killed in Chapter 18)
Second Return: 2.9 days
Third Return: 2.7 days
Fourth Return: 1.6 days
Fifth Return: 3 days

Based on the above, if you can return to Arberrang two times by the time you reach the Dredge Godstone, then you should be able to get just enough time to visit all five times and still reach your destination in time.

21a_pop_travel_daydreaming

Listen to all their stories. = progress

21a_pop_travel_fallingcliffs

"I don't care what's going on here, but it stops now!" = nothing
Let Valgard and Oli resolve this themselves. = nothing

Charge and break through the crowd. = Battle
Find a good spot to stand your ground. = Battle (harder)
Make your way around the masses. = timer+1, Battle

*Note: if you lose the final battle here, every hero except Iver, Juno and Eyvind will die.

21a_pop_travel_fieldofbodies
Hundreds can be seen from the hilltop, and they look suspiciously arranged. "This wasn't a battle," Valgard continues, noting the same. Juno and Eyvind have nothing to add. "Wait, what if this is a warning of some kind, for something ahead?
"I don't know or care. Let's get out of here." = nothing

21b_part1_pop_funeral
The fires are lit, and special bundles laid along the ship's edge tint the flames in different colors, a gleaming rainbow rising toward the sky, and a bridge for brave souls. You imagine the ship drifting out to sea as the fire burns low. The solemn audience begins to pile stones and soil atop to form the traditional tumulus.

21b_part2_pop_horseborn
A livid crowd of horseborn confront each other. You recognize Canary and Derdriu amongst them. At their hooves lay victims of the spat. Canary is waving her javelin threateningly- you can't be certain what has sparked them this time, or who is to blame.
Break up the two by force if necessary. = timer+0.5

Rally able bodies and help put it out. = progress
Let things play out on their own. = timer+0.3
This is an opportunity to press an attack. = timer+0.9

21b_part3_pop_vigilance
The warped have not been able to scale the black wall since coming here a day ago. Many want to take full advantage of the respite; others call it folly. Keeping a full watch now means forcing fatigued and wounded survivors to take turns. Some haven't slept in days.

Dig out as many bodies as you can see. = timer+0.2
Raise the collapsed wall back up to reach anyone who might be trapped underneath. = timer+0.1, Egil dies

*If Gunnulf is alive.

Fight on. = Battle

21b_part5_pop_laststand2
Your memories have become a series of tangled figures swinging dark weapons. You survived the last day of fighting, but Yrsa's suggestion is starting to sound more and more reasonable. The dream of rest is a siren's song.

*To my knowledge, Alfrun can only die at the very end of Chapter 21, if you lose the final battle before entering the tower.

Endings
