Overview
The Fools' Spring is an A-Class Synthesis Arc that turns defensive setup into offensive pressure. Its Solifugae Vita passive grants a flat ATK boost whenever the wearer has an active Shield, giving shield-generation characters both survivability and damage from the same equipment slot.
The Fools' Spring is a 4★ A-Class Synthesis-type Arc in Neverness to Everness. It rolls a base 395 ATK at Level 80 with a 52.5% DEF% substat. The primary skill, Solifugae Vita, defines its role across rotations and team compositions.
Lore
"If I were a cicada, I'd still sing with my raspy voice."
The flavor text sets the Arc's tone and gives designers a quick lens on how the Solifugae Vita passive is meant to feel in play.
Passive Effect
The Solifugae Vita passive provides the following effect at Refinement Rank 1: Increases ATK by 18% while the wearer has a Shield.
Refinement ranks raise these values without changing the trigger conditions. The table below lists the per-rank scaling.
Level | ATK While Shielded |
|---|---|
L1 | +18% |
L2 | +21% |
L3 | +24% |
L4 | +27% |
L5 | +30% |
Ascension Materials
Reaching Level 80 with full access to the Solifugae Vita passive requires six ascension breakthroughs. Each phase raises the level cap and unlocks the next refinement condition. The costs are fixed per Arc and do not scale with refinement rank.
Phase | Level Cap | Gold | Materials |
|---|---|---|---|
Phase 1 | Lv.30 | 16,000 | |
Phase 2 | Lv.40 | 32,000 | |
Phase 3 | Lv.50 | 48,000 | |
Phase 4 | Lv.60 | 64,000 | Master Drama Core x10, Blurred Silhouette x10 |
Phase 5 | Lv.70 | 80,000 | |
Phase 6 | Lv.80 | 96,000 | Collector's Drama Core x10, Chaos Silhouette x10 |
Compatible Characters
The listed compatible characters share the Arc's core synergy. Any character can equip any Arc regardless of element or skill fit, but these characters gain the full value of the Solifugae Vita passive thanks to their kits and scaling.
Character | Element | Rarity | Why It Fits |
|---|---|---|---|
5★ | S-Class Incantation DPS from ETD-4, whose spellcasting rotation benefits from consistent ATK and damage multipliers; a natural fit for the Solifugae Vita payoff. | ||
5★ | S-Class Psyche tank whose damage-redirect kit scales with survivability and sustained uptime; a natural fit for the Solifugae Vita payoff. | ||
4★ | A-Class Incantation butler whose shield- and buff-based support rotation pairs well with defensive and offensive Arcs alike; a natural fit for the Solifugae Vita payoff. |

Strategy Tips
Confirm your chosen character's rotation lines up with the Solifugae Vita trigger before investing refinement materials. An Arc whose condition you cannot reliably fire is worth less than a B-Class Arc you activate every rotation.
At Refinement Rank 1 the values in the passive table are baseline. Early ranks give the biggest jumps; the last couple of ranks are smaller gains and usually not worth duplicating a 5★ Arc unless the character is a dedicated main DPS.
Pair The Fools' Spring with Synthesis-aligned Drive Blocks and KongMu Gear. Matching element on support gear stacks multiplicatively with the Arc's passive.
Keep the ascension materials in mind when planning farming routes. The final two phases jump from a 6x to a 12x requirement, which is often the real blocker for hitting Level 80.
Review the Compatible Characters table before equipping. Element mismatch still works, but the biggest multipliers assume the passive's trigger and your character's rotation are synchronized.
