BRIGANDINE ABYSS Campaign Walkthrough
Opening seasons for Largo and Garnet, then the habits that carry a 30-hour path.
This walkthrough is spoiler-light on purpose. It will not list Event Battle scripts, later-nation twists, or who betrays whom in season forty. It will tell you how to open Gran Dragnica with Largo, how to open Scarlet Will with Garnet, and which mid-campaign habits keep a Story Mode run alive until the credits. A first path is about 30 hours. All six together pass 100 hours. Mission Mode is a separate sandbox with 24 win conditions—use it after you have survived locked borders and timed Event Battles once.
Nation lore, starting neighbors, and the other four Story Mode routes live on Story Campaigns and the Factions hub. Systems primers sit in Getting Started. This page is campaign pacing.
Before you unpause season one
Story Mode will refuse some invasions. If a nation is locked, attacking the border is wasted Attack declarations. Spend those seasons upgrading, training, and taking land you are allowed to hold. Event Battles are not optional skirmishes. They fire after a set number of seasons, they can pull leaders regardless of where you parked them on the world map, and losing one is game over. Keep a save before the window, keep story knights off long quests as the date approaches, and treat the fight like a raid: Rally plan, height plan, leader-hunt plan.
Do not spread to every adjacent castle in the opening. You deploy three squads. Every empty keep is an Invasion invitation. Upgrade with money and materials each season instead of painting the map. Details are on Base Building.
Gran Dragnica — Largo and the dragons (opening)
Gran Dragnica is the dragon-tamer path. Largo is your throughline. The demo used this nation for two seasons; retail continues the same thesis: your special tools often care about standing near dragon units or dragon-blooded leaders. In the opening, that means you do not split the dragon core across three distant fronts just because you can capture a village.
Opening habits. Build three squads that can actually stand on a hex line, not one deathball and two empty leaders. Put enough Command Points into a dragon-capable retinue that Largo is not walking into Invasion with two goblins. Rally is not optional flavor here—pulling a dragon-adjacent monster for a trait, then Dismissing when you need the body, is how cluttered melee maps stop wasting a turn. Read Rally System before you treat every lizard as fodder; Lizard Rally’s extra action is real and you will want a battery eventually, but Gran Dragnica’s identity is still the dragon package, not a lizard-only cheese file.
Land. Take adjacent, holdable keeps. Upgrade them. Do not ignore height on the first mountain maps; fliers exist so you are not walking every valley. When an Event Battle is on the calendar, pull Largo and the dragon core off optional quests. Mercenaries can sit on material runs. Named dragon knights should be in training or in the field.
What not to do. Do not assume Abyssloa is a season-three neighbor you can rush. Story Mode will gate the fight. Do not spend the opening farming a locked border. Do not dismiss the Organization Phase as menu homework—Gran Dragnica falls behind when its class-change items at 20 are still sitting on a quest you never staffed.
Scarlet Will — Garnet (opening)
Scarlet Will is Garnet’s company: a mercenary-shaped roster that has to stay liquid while the continent catches fire. The demo used this path for two seasons as well. Retail’s opening still teaches the same economy: you will hire people who can die forever, and you will regret sending Garnet to fetch ore.
Opening habits. Garnet is a story leader. Mercenaries are quest fodder. That split is the entire Scarlet Will tutorial, whether the game labels it or not. Staff Niffrom’s Market and quests with hirelings. Keep Garnet and other named officers free to defend and to Invasion. Class change at 10 is free of the item gate; the level 20 item is not. If you skip Quests and Training, Scarlet Will’s mid-game officers stall while NPC nations keep promoting.
Land and neighbors. Scarlet Will’s story frames a fight against Abyssloa and rival steel. You still cannot invade every grudge on the map. Locked nations stay locked. Capture what you can garrison. When Attack declarations pile up, remember troops moved in Organization are not at the castle you left.
Combat. Focus enemy leaders. Rally when a monster is blocked behind Zone of Control. Garnet’s maps in the opening are large and often empty—do not march the whole army as one blob into AoE. Combat Tips is the Invasion page; this walkthrough only insists you practice leader-hunting before Event Battles start using extra win conditions (escape timers, defend NPCs).
Mid-campaign habits (any Story Mode nation)
Once the opening is stable, every path converges on the same chores.
Calendar the Event Battles. They do not care that you own half of Meltitea. They also do not care that your best leader is three regions away on a training tick if you failed to park them. When the season count gets close, stop optional expansion, finish the item quests you already started, and stage three squads that can Rally on command.
Do not attack locked nations. The game will simply not let you. Re-read the Attack Phase instead of assuming the UI is broken.
Garrison for Invasion. NPC factions train. They also declare. A keep with no leader is a free conquest for someone else. If you must quest, quest with mercenaries.
Keep upgrading, but pick a core. Money and materials each season should go into the castles that feed your three squads, not into a decorative empire. Over-wide maps are why Story Mode reviews called the loop repetitive: you fight the same Invasion rules on large empty hex fields until the next Event Battle.
Command Points and class items. Monster promotions raise CP costs. You will break up cute lineups. Plan for it. Level 20 items are a quest and training problem, not a shop problem at the start. Faction leaders skip the item; everyone else does not.
Rally as a campaign skill, not a panic button. By mid-game you should know which monsters are batteries (Lizard extra action, movement traits, resists) and which monsters must stay as bodies for Zone of Control. If a leader dies while a monster is Rallied, you lose that absorbed creature along with the rest of the fleeing squad. Do not Rally your only flier into a leader who is standing on the front hex.
Accuracy and AI. Reviews from RPG Site, RPGamer, and others treated miss rates and suicidal enemy leaders as real. Play around them: magic when physicals bounce, do not bet an Event Battle on a 75% swing, and still hunt leaders because the AI will often deliver them.
After the first credits
Start another Story Mode nation or move to Mission Mode. The systems do not change; the win conditions do. For a buyer’s-level read of whether a second 30-hour path is worth it, see the Review. For what actually shipped at launch, see the Updates Hub. Demo players: those two seasons did not carry over. You are not behind. You just already know whether you like Organization menus.
Frequently Asked Questions
Quick answers to common questions about BRIGANDINE ABYSS.
Which Story Mode nation is the real tutorial?
Gran Dragnica and Scarlet Will. The demo used both for two seasons. They teach dragons-and-Rally and mercenary-versus-named-leader economics without requiring Mission Mode's weird win conditions.
Can I invade every rival as soon as I meet them?
No. Story Mode locks some nations until events fire. Declaring on a locked border wastes the Attack Phase. Expand where the game allows, and prepare for timed Event Battles instead.
How long is one campaign?
About 30 hours for a first Story Mode path. All six campaigns together are 100 hours or more. Mission Mode is extra on top of that.
Does this walkthrough cover later Event Battles beat-by-beat?
No. It stays spoiler-light: opening advice for Largo and Garnet, then mid-campaign habits that apply to every path. Nation pages cover who you are fighting and why.
