Umbral Monument marks a key endgame destination for commanders in Arknights Endfield.

This challenging domain becomes accessible precisely three weeks following the global launch.

Its arrival serves as a primary goal for squad development, encouraging deep investment in your operators.

Unlike modes unlocked through exploration, this is a timed release, aligning with long-term progression systems.

Prepare your roster and strategies for when this pinnacle of combat opens its gates.

Arknights: Endfield will introduce the Umbral Monument challenge starting February 12, 2026.

This endgame content kicks off with the "Those Forsaken by the Land" series.

Two weeks later, on February 26, 2026, the "Inorganic Construct" series will become available.

Alongside the Umbral Monument, a limited-time event called Monumental Etching will run concurrently.

The schedule for this event is as follows:

• "Those Forsaken by the Land" begins February 12, 2026, at 12:00 PM server time
• "Inorganic Construct" starts February 26, 2026, at 12:00 PM server time

While details about the differences between Umbral Monument and Monumental Etching remain scarce, it is expected that Monumental Etching functions similarly to the conventional memoir system seen in Honkai: Star Rail.

This means Umbral Monument is a permanent feature players can access anytime, whereas Monumental Etching offers additional rewards if all challenges are completed within the event’s limited duration.

The first two Monumental Etching events will likely conclude around the end of version 1.0, approximately between March 9 and March 12, 2026.

Rewards from the Umbral Monument include valuable items such as T-Creds, Marks of Perseverance, Advanced Cognitive Carriers, Arms Insp Sets, and Protohedrons.

Completing the Monumental Etching event also grants Oroberyl rewards, making it essential to finish these challenges within the event timeframe for extra benefits like additional pulls for the Endfield banners.

Umbral Monument presents a challenging combat experience with two distinct difficulty levels: Normal and Agony.

To access the Agony mode, players must first conquer the Normal mode.

In Normal mode, players have the advantage of using tactical items like the Buck Capsule [A] for healing during battles.

However, the Agony mode removes this option, requiring players to rely on skillful dodging and well-developed characters to endure the fight.

To increase survivability in Endfield, it’s beneficial to include sustain-focused operators such as Ardelia, Ember, and Gilberta in your team composition.

These characters provide essential healing and support, helping your squad withstand the intense challenges of Umbral Monument.
