How to Unlock Arknights Endfield Umbral Monument
Getting into Arknights Endfield Umbral Monument takes just a couple of straightforward steps.
- Reach Authority Level 30 or higher.
- Finish the main story mission Chapter I Process II: Paving the Way.
- Head to the Valley IV Hub Base and talk to Sergio Leon to start the dedicated Umbral Monument mission.
Once those are done, the mode opens up and stays available permanently. New series of stages get added over time through version updates, so there's always something fresh to tackle.
Normal vs Agony Mode in Umbral Monument Stages
Every Arknights: Endfield Umbral Monument stage comes in two versions. Normal mode acts as the on-ramp. Clear it first, and Agony mode unlocks for that same stage.
Normal mode lets you use tacticals and consumables. Enemies sit at reasonable levels, and the mechanics stay manageable with good positioning and basic crowd control. Most players clear Normal without too much trouble once their operators hit the recommended level shown on the stage select screen.
Agony mode turns the heat up. Enemy levels jump (often to 90), mechanics get enhanced, and you lose access to tacticals and consumables entirely. You rely only on your four deployed operators for healing, buffs, and sustain. The 10-minute timer still applies, but mistakes cost more because recovery options disappear. That said, Agony clears are what push your teams and give the upgraded medals.
Arknights: Endfield Umbral Monument Rewards Breakdown
Umbral Monument rewards come in clean layers. First clears give permanent resources. Series completion adds medals. Limited-time events on top offer extra currency during the launch window for each new series.
First Time Clear Rewards
The latest official series update notes for Contention of Deathly Silences confirm that first-time clears of the challenge stages reward items including Mark of Perseverance, Advanced Cognitive Carrier, Arms INSP Set, and Protohedron.
These resources directly help with operator development and account growth. First clears are one-time only — there are no repeat rewards for clearing the same stages again later. That makes it worth focusing on new series as soon as they open.
Series Completion Medals
Finish every stage in a series on Normal and you earn an Engraved Medal for that specific series. Push the same stages on Agony and the medal gets trimmed with extra visual flair. These medals serve as permanent proof of your clears and work great for collection or bragging rights in the community.
Monumental Etching Limited-Time Rewards
Every new series launches with its own Monumental Etching event. For the current Contention of Deathly Silences series, the event is called Monumental Etching: Dirge of Grief. It runs from the series launch on July 2, 2026 at 12:00 server time until the next version update.
During the window, complete various Umbral Monument challenges through the in-game Event Center to claim bonus rewards, especially Oroberyls. The tasks usually involve clearing stages on Normal or trying Agony. Claim everything before the event ends because these bonuses disappear with the next maintenance.
Recommended Team Compositions for Arknights Endfield Umbral Monument
One of the most reliable free-to-play compositions for the current Contention of Deathly Silences series (six floors) is the Zhuang Fangyi team. This setup excels in the longer format compared to previous three-floor monuments because it delivers strong personal DPS, fast-ramping utility, solid crowd control, and enough sustain to handle extended waves, and vortex-absorbing bosses without relying on slow-activating passives.
- Zhuang Fangyi serves as the main DPS carry. She uses her signature weapon Lone Barge. She is at Potential 0 but still provides the core damage output the team needs.
- Perlica brings excellent utility and support. She equips the Wild Wonderer weapon and a three-piece Jing Wei set, sitting comfortably at Potential 5.
- Akekuri uses the Thermite Cutter with a three-piece Frontiers set and is at Potential 5, giving the team quicker and more consistent value.
- Antal provides burst damage and area control. He runs the Detonation Unit with a three-piece Xiranite set and is at Potential 0.
Tips to Clear Umbral Monument Stages Effectively
Preparation beats brute force in Umbral Monument stages. Here are the approaches that show up consistently in successful clears.
- Always preview the recommended operator level and mechanics on the stage select screen. Enemy intel gives exact details on what each foe does.
- Build teams around sustain and utility first. Healers like Ardelia or Ember become essential in Agony since items are banned. Add strong crowd control (Gilberta shines for grouping) and DPS that matches the stage's main threat.
- Study the gimmick before pulling the trigger. Some stages feature damage-over-time mist, escalating attack buffs on mobs, summon phases, or enraged bosses that gain shields or power as HP drops. Interrupt channels, break key adds quickly, or manage positioning to avoid unnecessary damage.
- In Agony, every skill matters more. Save high-impact bursts for critical moments instead of spamming. Manage stamina and SP carefully because there's no item safety net.
- For the current Contention of Deathly Silences series with its six stages, the same principles apply across the board. Specific mechanics include prism effects that boost certain enemies, permanently enraged beasts, operators getting sealed at intervals, and bosses that absorb vortices for shields. Interrupt what needs interrupting and keep the team alive through the waves.
Moreover, strong gear and operator investment pay off fast here. Many players notice that once their roster hits solid investment levels, Normal becomes comfortable while Agony turns into a fun optimization puzzle rather than a wall.
Final Thoughts on Arknights Endfield Umbral Monument
The Arknights Endfield Umbral Monument delivers exactly what endgame players want: meaningful difficulty, permanent rewards that actually help progression, and fresh content that keeps the mode alive across updates. Take it series by series. Clear Normal for the easy resources and base medal, then decide how deep into Agony you want to go based on your current roster strength. The mode stays available, so there's no rush.
As you keep clearing those stages and collecting everything from T-Creds to Protohedrons, a quick top up through something like Lootbar for Arknights Endfield top ups can help you stay ready for the next series drop without slowing down your momentum.
