The orbment system in Trails in the Sky 1st Chapter can feel overwhelming at first, but mastering it transforms your party from struggling adventurers into unstoppable forces. Whether you're playing on Nightmare difficulty or just want to optimize your builds, understanding how sepith, quartz, and elemental lines work together is crucial for success.
Understanding the Orbment Foundation
What Are Sepith, Quartz, and Orbments?
Think of orbments as the magical devices each character wears - those pocket watch-looking accessories that power their abilities. Inside these orbments, you slot quartz (elemental orbs that provide stats and unlock spells). To craft quartz, you need sepith - the crystalline currency you collect from defeated enemies.
Sepith Set 1 for Nintendo Switch ...
Your sepith collection appears in the Items menu on the right side, showing seven elemental types: Earth, Water, Fire, Wind, Time, Space, and Mirage. There's also Sepith Mass - sell this immediately for quick money since it serves no crafting purpose.
tip
Always monitor your sepith reserves before spending. Unlocking orbment slots requires substantial amounts, and running low can halt your progression.
The Line System Explained
Every character's orbment contains elemental lines that connect specific slots. Estelle has two lines: a blue line (3 slots) and an orange line (4 slots). The central slot counts toward both lines, making it incredibly valuable for spell combinations.

Unlocking Arts Through Elemental Values
How Spell Acquisition Works
Unlike traditional JRPGs, you don't learn spells through leveling. Instead, reaching specific elemental values on a single line unlocks corresponding arts. For example, equipping one Fire quartz grants Firebolt, while two Earth quartz on the same line unlocks Earth Lance.
important
Elemental values only combine within the same line. Having Earth quartz on different lines won't stack their values.
Priority Spells for Early Game
Focus on these essential arts during the prologue and Chapter 1:
- Tear (1 Water): Basic healing spell
- Earth Lance (2 Earth): AoE earth damage, excellent for mine sections
- Curia (1 Water + 1 Mirage): Removes all debuffs plus minor healing
- Firebolt (1 Fire): Reliable single-target damage

Sepith Management Strategy
Slot Unlocking Priority
Sepith serves two purposes: unlocking orbment slots and crafting quartz. Always prioritize slot unlocking since each new slot dramatically increases your character's EP (around 50-100 per slot) and combat effectiveness.
The unlock costs follow this progression: 25 → 50 → 150 → 250 → 500 sepith per slot.
Recommended unlock order:
- Estelle's slots first (she's your primary healer)
- Joshua's slots second (consistent party member)
- Alternate between them for expensive slots
warning
Don't craft excessive quartz early game. Save sepith for slot unlocking unless you have significant surplus in specific elements.
Character Build Recommendations
Estelle
Estelle excels as a support-focused character with healing capabilities and secondary damage potential. Her lack of elemental restrictions makes her incredibly flexible.
Essential Quartz Setup:
- Mind 1 or HP 1 (Water element for Tear)
- Defense 1 + Break 1 (Earth combo for Earth Lance)
- Impede 2 (Mirage element, 60% art cancellation chance)
Line Positioning Strategy: Place Earth quartz on the same line for Earth Lance, and ensure Water + Mirage quartz share a line for Curia access.
Joshua
Joshua functions as your primary physical damage dealer with magical backup options. His Time element restrictions limit flexibility but focus his role effectively.
Core Quartz Loadout:
- Action 1 (Time, center slot - mandatory)
- Attack 1 (Fire element, +5% STR, unlocks Firebolt)
- Hit 1 (Essential purchase: +60 accuracy, +10 STR)
- Arts Defense 1 (Wind coverage before Scherazard joins)
Why Hit 1 Matters: Many enemies have high evasion stats. Without adequate accuracy, Joshua's powerful crafts and S-Crafts will miss consistently, wasting precious turns.
Scherazard
Scherazard arrives with most slots unlocked and solid default quartz. She balances physical attacks with magical capabilities effectively.
Optimization Adjustment: Switch Mind 1 and Attack 1 positions to enable Curia access. This places Mind 1 (Water) and Evade 2 (Mirage) on the same line, unlocking the powerful debuff-clearing spell.
Advanced Optimization Tips
Same Name vs Same Element Rule
You cannot equip multiple quartz with identical names, even different tiers. Impede 1 and Impede 2 cannot coexist on the same character, but Defense 1 and Break 1 (both Earth element, different names) work perfectly together.
Elemental Coverage Strategy
Ensure your party covers all damage types:
- Fire: Joshua with Firebolt
- Earth: Estelle with Earth Lance
- Wind: Joshua initially, Scherazard later
- Water: Healing focus rather than damage
info
Some enemies are completely immune to physical damage and reflect it back. Having diverse elemental options prevents impossible fights.
Mastering the orbment system early provides the foundation for tackling Nightmare difficulty and optimizing your party's potential. Focus on understanding elemental lines, managing sepith wisely, and building characters around their natural strengths. With these strategies, you'll transform challenging encounters into manageable victories while fully experiencing the depth Trails in the Sky First Chapter offers.
