Trails in the Sky 2nd Chapter BP Guide: Prologue Day 2

This Trails in the Sky 2nd Chapter BP guide focuses on the Prologue - Day 2 route, where exploration, investigation choices, and preparation affect your Bracer Point progress. The most important decisions occur at Le Locle Training Grounds and near the end of Grimsel Fortress.

The route begins in Saint-Croix Forest, continues through the training grounds, and ends with a fortress investigation and battle. Follow the area order below to collect useful equipment and avoid overlooking the book pickup.

Video Highlights:

  • The relevant route covers the Prologue and its investigation objectives.
  • Key rewards include equipment, quartz, and a missable book.
  • Dialogue choices can award additional BP before the Prologue ends.
Route Tip

Use the forest section to recover CP and prepare your party before entering the training grounds. The later fortress battles become easier when Wind Arts and healing options are ready.

Step-by-Step Route and BP Choices

The safest approach is to complete the Prologue Day 2 objectives in sequence. The forest provides early equipment and combat opportunities, while the training grounds contain the first major investigation choice. Grimsel Fortress then adds status hazards, hidden switches, and a final dialogue decision.

BP Priority

The documented dialogue choices are “Move to a new base” for BP +3 and “Call? There's no need” for BP +2. Select them when prompted if you are following the listed BP route.

1

Clear Saint-Croix Forest

Start by heading north and take the right path at the fork to find the chest containing Reinforced Leather. Return to the fork, take the alternate route, and continue toward the more open section. Cross the first bridge on the left to reach the monster chest containing Breeze. Continue north, take the right branch, and collect Enhanced Boots.

2

Manage Forest Threats

Rolling Thorns self-destruct when defeated and can deal heavy damage to nearby characters. Keep the party separated when possible. Shining Poms may appear beyond the Bush Lancers; use S-Crafts promptly if one appears, because they can escape quickly.

3

Investigate Le Locle

Examine the blood stains, Kurt's broken spear, the torn map, broken window, kitchen barrels, and communicator. After checking the communicator, select Move to a new base to receive BP +3.

4

Collect the Missable Book

Go upstairs and inspect the blue-marker book on the bed to obtain Gambler Jack - Vol. 1. This pickup has a narrow opportunity window during the sequence, so collect it before using the next fast-travel option.

5

Finish Grimsel Fortress

Explore the fortress, obtain the Night-Vision Goggles, use the healing device, and inspect the marked device on the upper floor. Before the Prologue-ending event, save your game and select Call? There's no need for BP +2.

Do Not Rush the Story

Do not trigger the next major event before collecting Gambler Jack - Vol. 1. The book series can support a later Finale trade, and the free collection opportunity in this segment is limited.

Combat Preparation, Equipment, and Fortress Hazards

Combat difficulty rises during the Grimsel Fortress segment because several enemies apply Blind or Delay. The route is manageable when you prepare for the area rather than relying only on physical attacks.

The most useful early pickup is Night-Vision Goggles, which remove Blind from the equipped character. Equip them as soon as possible, then use Wind Arts against common fortress enemies where appropriate.

Threat or resourceEffectRecommended response
Rolling ThornsSelf-destructs after reaching 0 HPSpread the party before the final hit
Blind statusReduces reliability in combatFind and equip Night-Vision Goggles
Pain BeetlesCommon fortress encounterUse available elemental Arts
CrybabyAppears in dark-area groupsKeep healing ready and control positioning
Huge FrogUses Water Cannon and can summon helpTarget its weakness and interrupt pressure
Healing DeviceRestores party resourcesUse it before progressing to the final event
Fortress Setup

Equip Wind Arts to both active characters when entering the dark section. The route also includes a Healing Device, so use it before the final upper-floor sequence and save before advancing.

Night-Vision Goggles

Removes Blind from the equipped character and is especially valuable in the dark fortress area.

EP 1

Found in a chest on the second floor after navigating the dark-room paths.

ID Unit

Found near the red marker on the third floor.

Stat Droplets

Collect Strength, Defense, Spirit, and Magic Droplets from the four cylinders.

On the second floor, begin by taking the left route to find the chest with Night-Vision Goggles. Return to the starting area, then follow the right-side path and continue north. Ignore the early exit until you have checked the side room containing EP 1.

The third floor is more direct. At the red marker near the staircase to the fourth floor, open the chest to obtain ID Unit. On the fourth floor, inspect the marked device and collect the four Droplets from the cylinders. Use the Healing Device before the next event.

Battle Positioning

When an enemy can summon reinforcements or attack in a line, avoid placing both characters together. Spreading the party reduces the chance that one attack disables the entire team.

Rewards, BP Tracking, and Completion Checklist

The Prologue Day 2 route combines permanent items with progress toward your BP total. The available report lists General Training at 2 BP, Midnight Attack at 3 BP with a displayed +11, and a total of 16 BP for the documented segment. Because the report combines multiple entries, use the individual objectives and dialogue bonuses as your practical tracking points.

The book pickup also matters beyond the Prologue. Collecting the Gambler Jack series contributes to a later Finale exchange, so treating the book as optional can create unnecessary cleanup.

Prologue Day 2 Goals:

  • Collect Reinforced Leather, Breeze, and Enhanced Boots in Saint-Croix Forest
  • Examine all six listed clues at Le Locle Training Grounds
  • Choose Move to a new base for BP +3
  • Collect Gambler Jack - Vol. 1 before leaving the training grounds
  • Choose Call? There's no need for BP +2
Completion Check

Before starting the final Prologue event, confirm that the book, both BP dialogue choices, and the fortress stat Droplets are complete. This creates a clean save for continuing into the next chapter.
