Overview
Arcs are weapon-like equipment items in Neverness to Everness that boost character stats and provide passive abilities. Each character equips an Arc to gain stat bonuses, triggered effects, and sometimes active abilities. The Arc system works alongside the KongMu Gear system to form a character's complete build. Arcs are classified into three rarity tiers: S-Class, A-Class, and B-Class.
Rarity Tiers
Arcs come in three main rarity tiers, each offering different levels of stat bonuses and ability complexity.

Tier | Count at Launch | Characteristics |
|---|---|---|
S-Class | 5 | Highest stats, most powerful abilities, and unique effects. |
A-Class | 7 | Strong and versatile. Many are competitive with S-Class in specific builds. |
B-Class | 12 | Solid baseline Arcs. Available early and useful as foundations. |
S-Class Arcs
Five S-Class Arcs are available at launch. These are the most powerful equipment items in the game.
Arc Name | Effect |
|---|---|
ATK +20%. Reduces enemy Chaos RES by 40%, making it a strong choice for Chaos-element characters and Chaos-reaction teams. | |
Provides a 32% CRT DMG stacking bonus, accumulating up to 4 stacks. Rewards consistent critical hits with escalating damage. | |
HP +40%. When the character uses their Ultimate, a random effect triggers: either a healing burst or a protective shield for the party. |
Two additional S-Class Arcs are confirmed to exist at launch, but their full names and effects have not been officially detailed as of the final beta test.
A-Class Arcs
Seven A-Class Arcs are available at launch, offering strong bonuses that can rival S-Class Arcs in the right team compositions.
Arc Name | Effect |
|---|---|
ATK +32%, Basic Attack damage +32%, Boss damage +20%. An excellent generalist choice for attack-focused characters. | |
After a successful Parry Attack, the next Basic Attack deals bonus Incantation damage equal to 320% of the character's ATK. Rewards parry-focused playstyles. |
The remaining five A-Class Arcs provide various stat bonuses and conditional effects covering defensive, support, and elemental damage specializations.
B-Class Arcs
Twelve B-Class Arcs are available at launch. These serve as stepping stones during early and mid-game progression. While their raw stats are lower than higher-tier Arcs, they provide useful baseline bonuses and are readily available through gameplay activities.
Acquisition
Unlike many gacha games, Neverness to Everness does not have a weapon banner. The Scarborough Fair gacha system is focused exclusively on characters. Most S-Class and A-Class Arcs are earnable through gameplay modes or purchasable with Tri-Key currency. Each S-Class Arc costs 25 Tri-Keys. A few A-Class Arcs can appear as drops from the gacha board's Miracle Box tiles, but the primary acquisition path is through gameplay.

This design decision separates character acquisition from equipment acquisition, meaning players do not need to split their gacha budget between pulling for characters and pulling for weapons.
Upgrade System
Each Arc has five upgrade levels. Upgrading requires materials gathered from gameplay activities such as Anomaly Commissions and resource nodes. Higher levels increase the Arc's stat bonuses and ability potency. A fully upgraded level-5 Arc can provide roughly double the stats of its base level-1 version.
Stat Categories
Arcs provide bonuses across several stat categories.
Stat | Effect |
|---|---|
ATK | Increases attack damage percentage. |
HP | Increases health pool. |
DEF | Increases defense percentage. |
Break Intensity | Increases the rate at which attacks fill the enemy's break meter. |
CRT DMG | Increases critical hit damage. |
Element DMG | Bonuses to specific element damage (Chaos DMG, Anima DMG, etc.). |
Cycle Rate | Affects Esper Cycle Meter charge speed. |
Build Integration
Arcs are one half of the character equipment system. The other half is KongMu Gear, which uses a Tetris-like placement system for secondary stat enhancement. Building an effective character involves selecting an Arc that matches the character's role (DPS, support, tank) and then optimizing KongMu Gear for complementary stats. Certain Arcs synergize with specific Esper Cycle reactions, making Arc choice an important factor in team composition.
