Tears Beneath the Mask is an S-Rank Gas arc in Neverness to Everness that pairs a high attack ceiling with a debuff tied to the wearer's Ultimate. Its appeal sits in the Nestbound Bird effect, which softens incoming enemy damage rather than purely amplifying offense, making it a flexible pick for Gas-type characters who reliably land their Ultimate.
Quick answer: Equip Tears Beneath the Mask on a Gas character (Sakiri is the listed build reference) to apply Warning Gaze with their Ultimate, reducing marked enemies' damage by 18% for 20 seconds.

Core stats and identity
The arc maxes at 512 Base ATK with a 27.5% ATK substat at level 80. The in-game flavor line reads, "Who stole my child? Was it you? Was it him? Or was it…" Its Gas typing locks it to characters that benefit from Gas-type scaling and team synergies.

| Max Base ATK | 512 |
| Max ATK Substat | 27.5% |

Nestbound Bird effect
The arc's signature passive triggers when the wearer's Ultimate connects. Enemies hit are marked with Warning Gaze and take 18% reduced damage for 20 seconds. The debuff does not stack with additional hits, so timing the Ultimate to coincide with a damage window matters more than repeated procs.
Because the effect is a flat damage reduction on the enemy, it functions as a defensive utility for the whole team rather than a personal DPS boost. Pair it with a character whose Ultimate has wide AoE coverage to spread Warning Gaze to as many threats as possible at once.

Best characters for Tears Beneath the Mask
The arc is restricted in practice to Gas-type wielders. Sakiri is the build that currently lists it as a recommended option, but every Gas character can equip it.
| Character | Type | Notes |
|---|---|---|
| Sakiri | Gas | Listed in build setup as a recommended user |
| Chiz | Gas | Compatible Gas-type option |
| Skia | Gas | Compatible Gas-type option |
Level scaling
Base ATK climbs steadily with each ascension, and the ATK substat advances by 2.75% per tier. The full scaling from 20 to 80 looks like this:
| Max Level | Base ATK | ATK Substat |
|---|---|---|
| 20 | 377 | 11% |
| 30 | 398 | 13.75% |
| 40 | 420 | 16.5% |
| 50 | 443 | 19.25% |
| 60 | 466 | 22% |
| 70 | 489 | 24.75% |
| 80 | 512 | 27.5% |

Total ascension materials
Taking Tears Beneath the Mask from level 20 to level 80 requires 420,000 Beetle Coin alongside Cold Dessert and Silhouette materials across three tiers. Plan farming around the Nest Bird boss and Anomaly Commission runs to cover the higher-tier drops.
| Material | Total Needed |
|---|---|
| Beetle Coin | 420,000 |
| Flavorless Cold Dessert | 14 |
| Fading Silhouette | 14 |
| Plain Cold Dessert | 18 |
| Blurred Silhouette | 18 |
| Special Cold Dessert | 18 |
| Chaos Silhouette | 18 |
Per-ascension cost and bonus
Each breakthrough adds a chunk of Base ATK and unlocks the next substat tier. The most expensive single step is the final push from 70 to 80, which alone requires 120,000 Beetle Coin plus 12 each of Special Cold Dessert and Chaos Silhouette.
| Ascension | Cost | Stat Bonus |
|---|---|---|
| 20 → 30 | 20,000 Beetle Coin, 4 Flavorless Cold Dessert, 4 Fading Silhouette | +21 ATK, 13.75% ATK |
| 30 → 40 | 40,000 Beetle Coin, 10 Flavorless Cold Dessert, 10 Fading Silhouette | +43 ATK, 16.5% ATK |
| 40 → 50 | 60,000 Beetle Coin, 6 Plain Cold Dessert, 6 Blurred Silhouette | +66 ATK, 19.25% ATK |
| 50 → 60 | 80,000 Beetle Coin, 12 Plain Cold Dessert, 12 Blurred Silhouette | +89 ATK, 22% ATK |
| 60 → 70 | 100,000 Beetle Coin, 6 Special Cold Dessert, 6 Chaos Silhouette | +112 ATK, 24.75% ATK |
| 70 → 80 | 120,000 Beetle Coin, 12 Special Cold Dessert, 12 Chaos Silhouette | +135 ATK, 27.5% ATK |

How to obtain Tears Beneath the Mask
There are three confirmed routes to add the arc to your inventory. The shop route is capped at four total purchases, so it works as a guaranteed pity if drops do not cooperate.
- Arc Selection shop: 25 Tri-Key per copy, limit of 4.
- Boss/Anomaly drop: Nest Bird encounter.
- Anomaly Commission reward.
Note: Warning Gaze does not stack. Re-applying the debuff with another Ultimate refreshes the 20-second window but does not increase the 18% reduction.
For Gas teams that lean on a single Ultimate-heavy carry, Tears Beneath the Mask offers a clean combination of raw ATK scaling and a team-wide survivability layer. Sakiri remains the cleanest fit on current build pages, with Chiz and Skia as practical alternatives if your roster leans that way.
