BRIGANDINE ABYSS Base Development Guide
Choose stronghold upgrades, Exploration assignments, recruits, and market purchases without starving your active squads.
Direct answer
Upgrade the stronghold whose bonus helps a squad you will field soon. Keep required defenders in place, send idle leaders to Exploration, cover one immediate roster or equipment gap, and invest the remaining materials in lasting base growth.
Quick answer
- Match the next upgrade to a near-term active squad
- Send only idle leaders on Exploration
- Transfer useful gear before buying duplicate pieces
Develop the next useful base
A stronghold earns its upgrade when the bonus changes a squad you will field in the next few seasons. Start from the next border fight or mission objective, identify the unit bonus that helps it, and invest there. A distant upgrade with no active beneficiaries can wait.
The Organization economy has three separate channels: Exploration returns resources, money, and experience; strongholds hire leaders and monsters; the traveling merchant supplies weapons and armor. Treating those as one pool of random activity makes it easy to overspend.
Audit the next two seasons
Before assigning a leader or spending materials, write down four facts:
- Which strongholds can be attacked next?
- Which squads must remain available for those battles?
- Which leaders are genuinely idle this Organization Phase?
- What single missing unit, item, or bonus would change the next fight?
This audit prevents the two common economy failures: sending a needed defender away and buying several small upgrades that never combine into a stronger fielded squad.
Run the Organization investment loop
- Lock the battle roster. Keep the leaders needed for defense or invasion at the correct strongholds.
- Assign Exploration. Send leaders outside that roster to bring back resources, money, and experience.
- Fill one concrete gap. Hire a leader or monster when the squad lacks bodies, or buy equipment when one stat problem blocks the next matchup.
- Transfer before buying. Move an existing item between units at the same base when only one of them needs it for the next battle.
- Spend materials on lasting value. Upgrade the stronghold whose bonus serves the chosen active units.
Repeat this loop after the map or mission objective changes. The best base to improve can change when the active front moves.
Choose the next stronghold by impact
| Question | Upgrade now when... | Wait when... |
|---|---|---|
| Will the bonus affect an active unit? | The beneficiary is assigned to a near-term battle | The units using it are idle or stationed elsewhere |
| Is the border secure? | Required defenders remain after Exploration assignments | The upgrade would leave the stronghold short of leaders or squads |
| Does it solve a real gap? | The bonus improves the role your formation lacks | It duplicates strength the squad already has |
| Is the value lasting? | Several future battles can use the bonus | A small immediate purchase solves the only urgent problem |
There is no universal first-base ranking in the confirmed rules. Geography, the active roster, and the next objective decide which bonus has value.
Separate three different growth channels
Exploration produces returns
Leaders who are not joining battles can return with resources, money, and experience. An idle leader has an opportunity cost, so Exploration should be the default assignment after required battle roles are covered.
Strongholds expand the roster
Hire leaders and monsters at strongholds when a squad is incomplete or you need another squad on the map. Recruitment answers a coverage problem; it does not automatically make an existing squad stronger.
Discovery expands the market
When a quest reveals an equipment item, that item becomes available for repeat purchases from the market. You only need the discovery once. Afterward, check the shop before spending more leader time hunting for another copy.

Use the next-battle budget rule
Spend on the smallest change that solves the next confirmed weakness:
| Need | First response | Why |
|---|---|---|
| Squad lacks enough units | Hire at a stronghold | Adds the missing body or role |
| One unit needs a specific stat | Transfer suitable gear | Avoids an unnecessary duplicate purchase |
| No suitable gear is available | Buy from the merchant | Converts Mel into an immediate battle fix |
| Active units already cover the fight | Upgrade the relevant stronghold | Turns surplus materials into a lasting bonus |
This rule keeps immediate readiness and permanent growth in the same plan. The beginner guide places it inside the full Organization and Attack cycle. When the campaign has already fallen behind, use the difficulty recovery plan to rebuild one stable border before expanding investment.
Confirm the investment paid off
Before ending Organization, verify one visible result:
- The intended active units now receive the stronghold bonus.
- The incomplete squad now has the leader or monster it needed.
- The discovered equipment appears as repeatable market stock.
- The next battle's key item is equipped on the unit that will actually fight.
If none of those changed, the spend probably did not solve the stated problem.
Fix a stalled economy
| Symptom | Likely cause | Correction |
|---|---|---|
| Materials never accumulate | Too few idle leaders are exploring | Keep the battle roster lean and assign the rest to Exploration |
| Mel disappears without a stronger squad | Duplicate or unfocused equipment purchases | Transfer existing gear and buy for one defined matchup |
| New recruits sit unused | Hiring occurred without a squad plan | Stop recruiting until a specific formation slot opens |
| Stronghold bonuses feel irrelevant | Upgrades followed location instead of active units | Move investment toward the strongholds supporting current operations |
Mission objectives can change the value calculation sharply. The Mission Mode guide explains why collection, debt, defense, and conquest goals need different investment priorities.
What this guide can confirm
The confirmed launch systems cover material-based stronghold upgrades, unit bonuses, Exploration returns, stronghold hiring, merchant equipment, repeatable stock after an item discovery, and same-base equipment transfers. The prioritization rules above are recommendations for combining those systems. Exact bonuses, prices, and item restrictions still depend on the stronghold, unit, and current campaign state.
