Quick Guide
  • Trails in the Sky 2nd Chapter quartz controls character stats, elemental values, and available arts.
  • Action quartz improves turn speed and is often more valuable than a small damage increase.
  • EP Cut and Cast help art users maintain and activate spells more efficiently.
  • Slot upgrades create stronger builds, but they also require careful sepith spending.
  • Check line colors before replacing a quartz so you do not lose an important art or bonus.

Trails in the Sky 2nd Chapter Quartz Basics

Trails in the Sky 2nd Chapter quartz is the main system for customizing character performance. Quartz can increase physical or magical statistics, improve turn order, add status effects, or unlock arts through elemental values. Because each character has a different orbment layout, the strongest setup is not simply a list of the highest-rank quartz.

Your first priority should be understanding the relationship between quartz effects, elemental values, and orbment lines. A quartz may look powerful on its own but still be a poor choice if removing it breaks an important art or prevents a better combination on another line.

Video Highlights:

  • Quartz examples include Attack 2, Defense 2, Cast 2, EP Cut 2, Action 2, and Impede 2.
  • Higher-rank quartz can create stronger builds but may not fit every available slot.
  • Action 3 and EP 3 are especially useful upgrades for advanced orbment setups.
  • Slot placement can force a choice between keeping current bonuses and gaining a new effect.

Cast quartzReduces art casting timeDedicated casters and hybrid characters
EP Cut quartzLowers EP costLong dungeons and repeated spell use
Elemental quartzAdds elemental valueUnlocking arts and meeting line requirements
Status quartzAdds a chance to inflict a conditionNiche control or boss preparation

Quartz also uses sepith, the currency required for synthesizing and upgrading orbment slots. Earth, water, fire, wind, time, space, and mirage sepith each contribute to different quartz recipes and line totals. Avoid spending every type immediately. Keeping a reserve makes it easier to react when a new slot, quartz, or story challenge becomes available.

Build Principle

Treat quartz as part of a complete orbment layout. A slightly weaker quartz that preserves a valuable art can be better than a stronger quartz that disrupts the entire line.

Physical Setup

  • Prioritize Action, Attack, Hit, and Strike quartz
  • Add Defense or Shield when survivability is an issue
  • Use status effects when the enemy is vulnerable

Art Setup

  • Prioritize Cast, EP Cut, and EP
  • Build elemental values around the arts you actually use
  • Keep enough EP recovery for longer areas

Control Setup

  • Use Impede, Hit, Evade, or status-focused quartz
  • Support turn manipulation and interruption
  • Favor consistency over maximum damage

How Elemental Values and Lines Work

Every quartz contributes elemental value to one or more elements. When enough value is placed on a line, the character gains access to corresponding arts. This means a quartz has two jobs: it provides its listed effect and helps shape the character’s spell selection.

Characters with multiple lines are generally easier to customize because you can separate physical bonuses from elemental requirements. A character with a more restricted layout may need to sacrifice a stat bonus to keep a key art available. This is why copying another character’s setup can produce disappointing results even when you own the same quartz.

Elemental focusTypical roleUseful planning question
EarthDefense and durabilityDoes this character need more protection?
WaterHealing and water-based artsDo you need reliable recovery?
FireOffensive powerCan the character safely use aggressive bonuses?
WindSpeed and wind-based artsWill this improve turn control or mobility?
TimeSpeed, EP, and control effectsCan you support fast turns or utility arts?
SpaceBroad offensive and support accessWhich mixed-element arts fit the line?
MirageMirage-oriented arts and utilityDoes the build need magical flexibility?

The most important decision is whether the line should be built around damage, support, or art access. A physical character may only need enough elemental value to unlock one or two utility arts. A dedicated caster usually benefits from a more deliberate arrangement because every lost elemental point can change the available spell list.

Watch the Line Requirement

Do not remove a quartz only because its displayed effect looks weaker. Check the line totals first. Removing it may disable an art, reduce elemental flexibility, or make a later slot upgrade less useful.

A practical method is to identify the character’s primary job before changing anything:

  • Front-line attacker: Start with Action, Attack, Hit, or Strike.
  • Defensive support: Add Defense, Shield, Earth value, and recovery options.
  • Dedicated caster: Start with Cast, EP Cut, EP, and the elemental values needed for core arts.
  • Hybrid character: Use one line for the main role and reserve another for utility.
  • Boss specialist: Adjust the layout for the expected status effects, resistances, and turn order.

In the late game, it is normal to compare a high-rank quartz against the setup it would replace. The upgrade may improve one statistic while lowering elemental access or removing a useful secondary effect. Test the full layout instead of judging the quartz in isolation.

Quartz Priorities for Combat

Combat quartz should be selected according to how often its benefit matters. A small attack increase is useful, but acting earlier can provide more opportunities to attack, heal, interrupt, or reposition. For that reason, Action quartz is one of the safest general recommendations for active characters.

The referenced progression includes Action 2 and the eventual pursuit of Action 3, along with EP Cut 2, Cast 2, Hit 2, Impede 2, and other rank-two quartz. These upgrades illustrate an important rule: higher-rank quartz can be excellent, but the best choice depends on slot compatibility and the role of the character.

PriorityQuartz typeWhy it mattersRecommended user
1ActionImproves turn frequencyMost combat characters
2CastReduces time spent preparing artsCasters and support mages
3EP CutPreserves EP across encountersLong-range art users
4AttackRaises physical damageDedicated attackers
5HitImproves reliability against evasive enemiesPhysical characters with accuracy issues
6ImpedeSupports art interruptionCharacters with good turn access
7Defense or ShieldImproves durabilityFront-line or fragile characters
8EvadeSupports avoidance-focused buildsCharacters with suitable positioning and bonuses

Action

Best general priority. More frequent turns improve damage, healing, interruptions, and item use.

Cast

Caster priority. Shorter casting windows reduce the chance of being interrupted before an art activates.

EP Cut

Efficiency priority. Lower spell costs help conserve EP during extended exploration.

Impede

Control priority. Useful when enemies rely on arts and the character can act before the spell resolves.

A common mistake is placing every offensive quartz on one character while leaving the rest of the party without speed or utility. A balanced group usually performs better when one character specializes in physical pressure, one supports arts and healing, and the remaining members cover control, defense, or flexible damage.

Practical Recommendation

If you are unsure where to start, place Action on your most frequently used character, Cast or EP Cut on your main caster, and defensive quartz on the member who takes the most direct attacks.

Step-by-Step Orbment Setup

Use this process whenever you receive a new quartz, unlock a slot, or reach a shop with upgraded options. It prevents accidental loss of arts and keeps sepith spending focused.

1

Identify the Character’s Role

Decide whether the character is mainly a physical attacker, caster, healer, control specialist, or hybrid. Start with the role that appears most often in your planned party.

2

Record the Current Line Bonuses

Check which arts and elemental totals are currently available. Note any important healing, offensive, or utility art before removing a quartz.

3

Install the Highest-Value Core Quartz

Add Action for a general combat setup, Cast or EP Cut for an art user, or Attack and Hit for a physical attacker. Do not spend a key line bonus just to gain a minor stat increase.

4

Compare the Replacement Cost

Before upgrading, check which quartz must be removed and what it currently provides. A rank-three quartz can be worse for the build if it breaks the line or removes a needed art.

5

Test the Finished Layout

Review the art list, statistics, and turn-order benefits. Enter a normal encounter or training area and confirm that the new setup performs as intended.

Setup phaseCheck before confirmingCommon mistake
Role selectionMain job and expected party positionBuilding every character for damage
Line reviewCurrent arts and elemental totalsForgetting a lost healing art
Quartz choiceEffect, rank, and elementChoosing only by rank
Slot upgradeSepith cost and replacement quartzSpending all reserves too early
Final testArts, stats, and turn behaviorNot testing the complete layout
Use a Temporary Test Build

When a new quartz looks promising, move it into an available slot first and review the result before permanently replacing a core option. This makes it easier to compare Action 3, EP 3, and other expensive upgrades.

The most difficult choices often involve a high-rank quartz that does not fit the current layout. For example, upgrading to Action 3 may require removing a quartz that supplies valuable elemental access. In that situation, compare three outcomes:

  • Keep the existing layout and preserve current arts.
  • Install the high-rank quartz and accept a smaller art list.
  • Rearrange another line so both the speed bonus and essential art access remain available.

There is no universal answer. The correct choice depends on the character’s job, the rest of the party, and the encounter ahead.

Sepith, Slot Upgrades, and Resource Planning

Slot upgrades are essential for making advanced quartz setups possible, but they are also one of the easiest ways to waste resources. A newly upgraded slot may allow a powerful quartz, yet the upgrade cost can delay another character’s improvement or leave you short of the sepith needed for a key recipe.

A sensible order is to improve the slots used by your most active characters first. Give priority to characters who remain in the party frequently, then upgrade specialized members when a specific story battle or optional challenge demands them.

Quartz Planning Checklist:

  • Confirm the character’s main combat role
  • Check line totals before removing any quartz
  • Reserve sepith for important slot upgrades
  • Compare Action, Cast, and EP Cut before choosing a replacement
  • Review the final arts and statistics after every major change
Resource decisionSafer approachWhy it helps
Early sepith spendingUpgrade frequently used characters firstKeeps your main party effective
High-rank quartzTest the layout before committingPrevents accidental loss of key arts
Limited elemental valuePreserve the line’s main purposeAvoids unfocused builds
New character joiningReuse spare quartz temporarilyDelays expensive purchases until the role is clear
Boss preparationAdjust after saving your current layoutMakes it easier to restore the normal setup
Do Not Chase Rank Alone

A rank-three quartz is not automatically the best upgrade. If its slot cost removes Action, Cast, EP Cut, or a required elemental value, the complete build may perform worse.

Keep a small stock of useful lower-rank quartz. Rank-two options remain valuable for secondary characters, temporary party members, and alternate builds. Selling or dismantling every older quartz can make later adjustments more expensive, especially when you want to create a specialized setup for a difficult encounter.

Quartz FAQ

Q: What is the best quartz to equip first in Trails in the Sky 2nd Chapter?

Action is one of the safest general choices because faster turns improve attacks, healing, interruptions, and item use. Dedicated casters may prefer Cast or EP Cut depending on whether casting time or EP consumption is the larger problem.

Q: Should I always replace a lower-rank quartz with a higher-rank version?

No. Compare the effect, elemental value, slot placement, and arts that would be lost. A lower-rank quartz can remain the better choice when it preserves an important line bonus.

Q: Why did removing one quartz disable an art?

Arts depend on elemental totals across an orbment line. Removing a quartz can lower one element below the required threshold, even if the removed quartz did not appear to be an art-focused option.

Q: Is EP 3 better than Action 3 for a caster?

It depends on the build. EP 3 supports a larger EP pool, while Action 3 improves turn frequency. Choose EP 3 for sustained spell capacity when EP is limiting you, or Action 3 when acting sooner provides greater value.

Final Takeaway

Build around the character’s role, protect important line totals, and compare the complete orbment layout before spending rare sepith or replacing a core quartz.
