The Shell system in Etheria: Restart is one of the game’s core progression mechanics, acting as both your weapon system and the primary source of passive stat bonuses. To fully maximize your characters’ potential, it’s essential to understand how the Shell system works—starting from how to obtain Shells, their rarity levels, class types, and how passive abilities are assigned and optimized.
What Is the Shell System in Etheria Restart?
Shells serve as character-bound weapons that not only grant special abilities but also offer passive stat bonuses through three customizable slots. These Shells enhance your team’s performance in both PvE and PvP content by boosting critical attributes such as attack power, defense, healing efficiency, or elemental damage.
Unlike gear systems in traditional RPGs, Shells in Etheria Restart are tied directly to the character and heavily influence their in-game role. Each Shell is unique, with a combination of rarity, class, and passives that define how well it supports your strategy.
Shell Classes – Role-Based Equipment
Shells are categorized into four main classes, each aligning with the roles in your team composition:
Striker: Focused on maximizing offensive output with ATK, Crit DMG, and SPD boosts.
Supporter: Enhances buff/debuff capabilities with Effect Accuracy and utility-focused passives.
Healer: Boosts healing done, healing received, and increases survivability for support units.
Survivor: Increases HP, DEF, and reduces incoming damage—ideal for tanks and frontliners.
Knowing which Shell class fits each unit is critical to optimizing performance during high-level content.
Shell Rarity – From Rare to Mythical
Shells come in several rarity tiers, which impact the strength of their stats and the number of available passive slots:
Rare (Blue): Basic Shells with fewer passive effects.
Unique (Purple): Mid-tier Shells with one or two strong passive stats.
Epic (Red): High-tier Shells that unlock multiple powerful passives.
Mythical (Gold): Endgame Shells with top-tier stats and effects—extremely rare and powerful.
Shell rarity not only affects the base stats but also determines the strength ceiling of the passive abilities assigned to it.
How to Obtain Shells – Grim Pursuit Boss Runs
Shells are primarily obtained through the Grim Pursuit mode, a boss challenge featuring 10 progressively harder fights. The higher the difficulty and the stronger the boss defeated, the better the chances of obtaining a Unique, Epic, or even Mythical Shell.
Key points:
Boss difficulty influences drop rates.
Certain bosses may have better chances of dropping class-specific Shells.
Farming Grim Pursuit is the main method for building up a strong inventory of viable Shells.
Shell Passive Ability Slots
Each Shell comes with up to three passive ability slots, which unlock through leveling up the Shell and using the Ascend system.
Slot 1 – Basic Stats
This slot usually contains basic stat enhancements, such as:
+ATK
+HP
+DEF
These passives provide a solid baseline and are always active once the Shell is equipped.
Slot 2 – Combat Enhancers
The second slot includes offensive or utility combat stats, like:
Crit Rate
Crit Damage
Speed
Healing Effect
Effect Accuracy
Effect Resistance
This is the slot where you’ll find the most meaningful buffs that shape the playstyle of your character.
Slot 3 – Advanced Effects
Unlocked via Shell Ascension, this slot adds high-impact passives, such as:
Increased overall damage
Damage reduction
Bonus elemental damage (e.g., Light, Dark, Fire, etc.)
These effects often define endgame builds and should be prioritized when building your best units.
How to Reroll Shell Passives
Rerolling Shell passive abilities is possible using the following materials:
Training Data: Used for rerolling general passive stats.
Reconfigure Chips: Target specific slots and reset passives selectively.
Players aiming for min-max optimization will frequently reroll their Shell passives to get ideal combinations (e.g., Crit DMG + SPD + Total Damage).
Pro Tip:
Focus on rerolling Shells for your core team first, especially high-rarity Shells. Passive optimization on Mythical Shells can drastically improve battle performance.
Shell Optimization and Team Synergy
When choosing or upgrading a Shell, consider the class synergy and role of the character:
DPS units benefit from Striker Shells with Crit DMG or Total Damage passives.
Support characters work best with high Effect Accuracy from Supporter Shells.
Healers shine when paired with Healing Effect and Effect Resistance passives.
Tanks or bruisers require Shells that boost DEF, HP, and offer damage mitigation.
Combining the right Shell class with targeted passive rerolls ensures your unit performs to its highest potential across all game modes.
Final Thoughts
The Shell system in Etheria Restart is a deep and complex part of progression, offering strategic layers far beyond simple stat upgrades. Whether you’re farming Grim Pursuit bosses for high-tier drops, rerolling passive slots for ideal stats, or matching the right class to your character’s role, every step counts.
Mastering Shells means mastering the game. Be patient, farm wisely, and focus on developing your best Shells first. Over time, the combination of optimal passive effects and correct class assignment will significantly elevate your team’s overall power.
