In the world of Arknights: Endfield, various high-difficulty dungeons constantly challenge players. Among all the dungeons, the Memory Abyss is undoubtedly the most difficult, with the least number of successful completions. To help more players successfully complete this dungeon, we are sharing a strategy guide for the Memory Abyss in Arknights: Endfield. By following the content of this guide, you too can become one of the few who have cleared this dungeon.

To clear the Memory Abyss, players first need to select the right team composition. We recommend choosing Ember, Sissi, Lifen, and our main character, the Administrator. It's also important to understand the weapons, equipment, and characteristics of each character.
Lifen is the primary core damage dealer in this lineup, while Ember, Sissi, and the Administrator will serve as support roles.

For weapon selection, Lifen is recommended to equip the Fushan, which enhances her agility and critical hit rate. The Administrator should use the Iron Echo, a weapon that increases agility and attack power. Ember should be equipped with the Past Masterpiece, which mainly boosts the ultimate skill's charge efficiency and primary stats. Sissi’s weapon can be chosen freely, as long as it is a 6-star high-will weapon, such as Chivalry.
For equipment, Lifen should use the Police Officer set, choosing either agility or willpower attributes. When fighting small monsters, bring 2 crit damage, and for deeper levels, bring 1 crit damage and 1 Point Sword set to increase charge efficiency. The Administrator should directly equip the Point Sword set and two ultimate energy acquisition efficiency accessories.

When challenging the Memory Abyss, after selecting the character lineup, players also need to understand the characteristics of each character. Lifen's main skill, Purify Body, can apply a Purification Mark, which reduces the enemy's physical resistance. The Administrator's combo skill can apply an Originium Crystal, and the passive skill is that when the Originium Crystal seals the enemy, the enemy will receive an additional 20% physical damage. This means that after using the combo skill, Lifen's physical output can be enhanced.
Ember's combo skill allows her to heal after being hit, and her talent is that after hitting an enemy with the combo skill, it reduces the enemy's defense by 20%. Sissi's role is straightforward; she provides healing to teammates.

After selecting and equipping the characters, weapons, and gear, you can start the challenge of the Memory Abyss in Arknights: Endfield. This lineup can directly lead you to a 5-star completion of the Memory Abyss.
