Oblivion is a 6★ Arts Unit in Arknights: Endfield, sold through the Acquisition Center's Arsenal Exchange rather than pulled from banners. It scales Arts damage through a large Arts DMG Dealt passive, a flat Intellect boost, and a critical rate buff that stacks conditional Arts DMG after ultimates and combo skills.
What Oblivion is
Oblivion (internal name wpn_funnel_0009) is a 6★ Arts Unit weapon. It is obtained from the Acquisition Center's Arsenal Exchange, making it one of the few 6-star weapons you can target directly with shop currency instead of the headhunting system. It can be leveled to 90 and breakthrough four times, unlocking higher skill caps at each stage.
The weapon is not a character signature. In lore, it is described as an Arts unit built by Witching Hour using an unidentified material beyond its core Originium circuitry.
Stats and scaling
| Level | Base ATK |
|---|---|
| 1 | 50 |
| 20 | 145 |
| 40 | 245 |
| 60 | 345 |
| 80 | 445 |
| 90 | 495 |
At max level with all passives at rank 9, Oblivion contributes 495 ATK, +156 Intellect, and +43.33% Arts DMG Dealt before factoring in its potential skill.
Weapon skills
Oblivion carries three effects: a flat Intellect passive, an Arts DMG Dealt multiplier, and the potential skill Twilight: Humiliation, which is what actually defines the weapon. Twilight: Humiliation grants a permanent critical rate and layers two separate Arts DMG Dealt buffs. One triggers on ultimate casts, the other on combo skill casts. They do not stack with themselves, but the ultimate and combo skill buffs apply independently, so a wielder who weaves both can hold both simultaneously.
| Rank | Intellect | Arts DMG Dealt | Crit Rate | Ult buff (15s) | Combo buff (15s) |
|---|---|---|---|---|---|
| 1 | +20 | +5.56% | +5% | +24% | +12% |
| 3 | +52 | +14.44% | +7% | +33.6% | +16.8% |
| 5 | +84 | +23.33% | +9% | +43.2% | +21.6% |
| 7 | +116 | +32.22% | +11% | +52.8% | +26.4% |
| 9 | +156 | +43.33% | +14% | +67.2% | +33.6% |
Pulling duplicates raises Oblivion's potential level, which further improves Twilight: Humiliation.
Best characters for Oblivion
Because the kit rewards both ultimates and combo skills with Arts DMG, it slots best into Arts-focused damage dealers who cast frequently.
| Character | Rarity | Element | Fit |
|---|---|---|---|
| Perlica | 5★ | Electric | Strongest personal-damage option; she leans supportive, so value depends on playstyle |
| Zhuang Fangyi | 6★ | Electric | Arts DPS profile that uses the full buff stack |
| Ardelia | 6★ | Nature | Works as a Phys sub-DPS/support build using the Intellect and Arts DMG lines |
| Gilberta | 6★ | Nature | Viable for solo DPS setups at high investment |
| Xaihi | 5★ | Cryo | Secondary option when an Arts Unit is available |
| Antal | 4★ | Electric | Budget slot for an Arts Unit user |
Among these, Perlica is the most common target because she is widely owned and scales well with the ultimate and combo skill triggers. Keep in mind, she is more often built as a supportive unit, so Oblivion mostly matters when you deliberately push her as a main damage dealer.
Upgrade costs to level 90
Bringing Oblivion from level 1 to 90 requires 2,524,080 weapon EXP and 341,390 gold, plus the breakthrough materials at levels 20, 40, 60, and 80.
| Breakthrough | Unlocks at | Key materials | Gold |
|---|---|---|---|
| 1 | Lv. 20 | 5× low break material, 3× spcstone 1_1 (Valley IV) | 2,200 |
| 2 | Lv. 40 | 18× low break material, 5× spcstone 1_2 (Valley IV) | 8,500 |
| 3 | Lv. 60 | 20× high break material, 5× spcstone 1_3 (Wuling) | 25,000 |
| 4 | Lv. 80 | 30× high break material, 16× skill specialize 1, 8× spcstone 2_1 (Wuling) | 90,000 |
Each breakthrough also raises the skill cap for Oblivion's three effect slots, so reaching Breakthrough 4 is required before the passives can sit at rank 9 and the potential skill at rank 4.
Is Oblivion worth buying from the Arsenal Exchange?
The answer depends on whether you have, or plan to build, an Arts carry. A 6★ weapon from the Arsenal shop costs close to what 13 standard pulls would, so the opportunity cost is real. For most players who already have a 5★ Arts Unit covering the role, there is little reason to prioritize Oblivion over saving currency for a character-signature weapon later.
Oblivion is worth the spend if you main Perlica, Zhuang Fangyi, or another Arts DPS and want the best non-signature option available for them right now. Outside of that narrow case, the shop currency generally returns more value on lower-rarity weapons that cover the same combat role.
