Stygian Onslaught reset with the arrival of Version 7.0, and with it came a fresh batch of weapon skins locked behind the mode’s hardest tier. There are five sets, one for each weapon type, and every character who wields that weapon type can use them.
Quick answer: Clear Stygian Onslaught on Dire difficulty (solo, all three bosses) to receive all five Radiant Phantasm weapon skin sets. Finish all three bosses within a combined 180 seconds to get the 5-star variant with the enhanced glow.
The five 7.0 weapon skin sets
Each set covers one weapon category, and every skin comes in variants that match all elemental visual styles. Nothing here changes stats — these are cosmetic overlays, closer to a character outfit than a gear swap.
| Skin set | Weapon type |
|---|---|
| Golden Bough of Nemorensis | Sword |
| Silver Radiance of Gradlon | Claymore |
| Starlight of Fylkir | Polearm |
| Dawnstar of Shahar | Catalyst |
| Yayu | Bow |
Golden Bough of Nemorensis is the sword set, usable by any sword character in your roster once the reward lands in your account.

Silver Radiance of Gradlon covers claymores, which means it applies to everything from Mavuika’s greatsword to older four-star claymores.

Starlight of Fylkir is the polearm set. Any polearm user can equip it, with the visual effect adjusting to the character’s element.

Dawnstar of Shahar handles catalysts, so Nahida, Citlali, Klee and every other catalyst user can swap into it.

Yayu rounds out the list as the bow set, available to every bow character.

Stygian Onslaught runs across six tiers — Normal, Advancing, Hard, Menacing, Fearless, and Dire. The skins only drop at the top. Normal through Hard support matchmaking co-op and are forgiving enough for most accounts. Menacing is where the mode starts demanding three separate teams with no shared characters, and Fearless and Dire are solo-only.
| Requirement | Detail |
|---|---|
| Difficulty | Dire (the sixth and final tier) |
| Party setup | Three non-overlapping teams, one per boss |
| Co-op | Not allowed — Dire is solo only |
| Time per boss | 120 seconds |
| Bonus condition | All three bosses cleared in 180 seconds combined |
| Resin cost | None for the skins |
Note: the 180-second target is the combined total across all three fights, not per boss. Clearing Dire without hitting that total still gives you the skins, just in the standard four-star version instead of the glowing five-star one.
How to equip the skins in the Dressing Room
You know it worked when the weapon model on the character preview changes and the skin shows as equipped in the Weapons tab. If a skin does not appear as an option, the Dire clear has not registered on that account.
The skins expire when the cycle resets
These are not permanent unlocks. The Radiant Phantasm sets stay usable only for the current Stygian Onslaught cycle. Once the mode rotates with the next patch, they disappear from your inventory and you have to earn the new batch by clearing Dire again.
That framing matters when deciding how much to invest. The skins are cosmetic and temporary, and the mode’s other rewards — Primogems, Mora, character EXP materials, and Dust of Enlightenment for artifact substat rerolls — are all reachable well below Dire. Clearing Hard opens the Resin-based artifact rewards during the Disturbance Outbreak window, and Fearless still pays out the same core rewards as Menacing.
Version 7.0 went live on August 12th, 2026, and the current Stygian Onslaught cycle opened on August 19th. If your roster is not deep enough for three independent Dire teams, the practical move is to take Fearless for the primary rewards and treat the skins as a stretch goal rather than a checklist item.
