Memorial Arena
Last updated 2026-01-06
The Memorial Arena is a battlefield simulation system designed and built by Schicksal for training Valkyries. Actual data is used to simulate the most powerful enemies encountered in the Honkai-verse. Valkyries would attempt these challenging boss fights to improve their combat skills.
Memorial Arena, as its name implies, is a game mode where Captains can face off against challenging bosses from previous encounters. The virtual battlefield uses data to recreate enemies and have them battle with Valkyries with the aim of increasing Valkyries' battle prowess.
Memorial Arena is unlocked at Captain Level 38 and runs from Tuesday, 04:00 to Monday, 02:00 every week. Between Monday 02:00 and Tuesday 04:00, results are calculated and rewards are distributed.
Battling Enemies
Enemies in the Memorial Arena have their memory upgraded with ranks "C, B, A, S, SS" with each letter corresponding to a different difficulty level. Once a Captain has defeated an enemy at a certain difficulty level, they will automatically move up to the next difficulty level. After certain difficulty levels, enemies in the arena will begin to use different attacks and sometimes even special ultimate skills when damaged enough.
The Exalted bracket also features 2 SSS rank Bosses (as of Version 6.1, including 20% UP one, and one at the middle) which the Captain can challenge to get bonus score-based rewards. In addition, there's also [Buffed Mode] that can be enabled before the encounter. This will overall benefit a team during battle, in exchange for score loss at the end of the fight.
Buffed Mode
- Added in Version 5.1, activate Buffed Mode to enable a special effect but lose a portion of Boss score (when it's activated, the full score equals the base score before the activation).
- Recommended for fast clearing.
- Effect: Every 30s in battle, enemies take 20% more DMG and team restores 1,500 HP as well as 15 SP.
Locked Gears & Valkyries
Once a Valkyrie or a gear is used for a Memorial Arena boss, the Valkyrie or gear is locked to that boss. In addition, unawakened and awakened forms of the same Valkyrie cannot be used for the same boss — even if they are used in different attempts. The lock is finalized when an attempt is registered — ie. by either defeating a boss or being defeated without exiting early. For example, if 
Valkyrie Pledge equipped with Oath of Judah is used to defeat C Rank RPC-6626, both Valkyrie Pledge and that particular Oath of Judah will not be usable on any other boss; in addition, 
Luna Kindred — Valkyrie Pledge's awakened form — cannot be used for RPC-6626 at any rank. This, however, does not restrict a different Oath of Judah in the Captain's inventory to be used for another boss. These restrictions also do not apply to [Training Mode].
Training Mode
- In Training Mode, Captains can challenge the boss on any difficulty. This includes difficulties that have not been passed yet.
- Points scored in Training Mode will not be added into the real score. This mode is only for training, and the Captain's Valkyries and equipment will not be locked here.
- Captains can use any Valkyries and any equipment here, including those already locked in real battles.
Finalization
Memorial Arena performance is finalized every week. Opening time: Tuesday 04:00 to following Monday 04:00. Finalization time: Monday 04:01 ~ Tuesday 03:59. During this time, the Memorial Arena system will automatically tally the Captain's performances in battle. Captains will not be able to fight in the Memorial Arena during this time.
Boss appearances will differ per week. Rankings and boss levels will be reset by the Memorial Arena system. Battles that end after the finalization time will not be finalized. There might be a one-to-two-minute delay during finalization due to network latency. All locked gears and Valkyries will also be reset.
Scoring
The maximum score for each boss goes up as a Captain beats a higher rank of that boss. The actual score is reduced by the amount of in-game arena time the Captain spends beating the boss of that rank (time spent on previous rank are not counted). At SS Rank, every in-game second spent equates to 53-point reduction, and each SS Rank boss allows for a maximum score of 31,946 which equivalent to defeating them with 0-second wasted. Captains can challenge the same boss again at SS or SSS (Exalted only) Rank. Only the highest score achieved will be counted.
Each rotation there is also one boss that gives a bonus 20% to the score achieved against it.
During a boss encounter, if a Captain is defeated either by losing all Valkyries or by the timer running out, the Captain will lose a challenge attempt. A score based on the remaining health of the boss and its rank will be awarded — although much less than the score from defeating the boss. If the Captain abandons during an encounter, no score is awarded but no challenge attempt is consumed either.
Brackets
- Captains are placed into 4 different brackets based on their Captain Level.
- Basic (Lv. 38-55): 2 bosses; 4 attempts per day.
- Elites (Lv. 56~69): 2 bosses; 4 attempts per day.
- Masters (Lv. 70-80): 3 bosses; 5 attempts per day.
- Exalted (Lv. 81-88): 3 bosses; 6 attempts per day.
- If a Captain levels up during a rotation, they will not move up in bracket until the next rotation.
- The difficulty of the bosses increase significantly as a captain moves up in brackets. For example, a Rank S boss may pose a significant challenge for a level 70 Captain in Masters even though the Captain can achieve good scores with same boss at Rank SS previously in Elites. The additional 3rd boss may be out of reach due the sudden requirement for a 3rd team of Valkyries along with their gears. Memorial Arena is thus one of the reasons that it is advisable to slow down leveling above level 50 or level 60 — depending on active events of the time.
Exalted
Added in Version 3.4, the Exalted Division offers SSS Rank Bosses. Captains will need to defeat the Boss on SS Rank first to challenge them. SSS Rank Bosses offer bonus score rewards (
Ancient Willpower, 
Ancient Legacy, and 
Crystals).
Memorial Arena Exalted LITE
The permanent LITE function is currently available in Exalted bracket. Once the Captain defeats the UP boss at SS or SSS Rank, they can use that to auto-defeat bosses on the next rotation up to S or SS Rank respectively, at the cost of one attempt per use. Highest-difficult bosses (SSS Rank) cannot be auto-defeated by Arena LITE.
Rewards
Gyakushinn Miko Souls, this was changed in a later update into 
Imayoh Ritual Souls.At the end of each week, Captains can receive tier rewards based on their total scores from all bosses, as well as rewards based on their relative ranks in their respective tiers. Ancient Willpowers and Ancient Legacy ×Ancient Legacy, which can be obtained from Lv. 70 onward, received from Memorial Arena can be used in the 
War Treasury.
Score rewards are accumulative. A Captain will receive rewards from all reward tiers up to their score. In contrast, Captains only receive ranking rewards of their interval. For example, a Captain with a total score that ranks at 12% in Basic will receive rewards tier 12.50% as 12% is between 5.00% and 12.50%. But the Captain does not receive rewards for intervals below 12.50%.
