If you’ve spent any time scrolling Honkai Star Rail community forums or watching endgame playthroughs, you’ve almost certainly seen players rave about the rare rewards from Forgotten Hall. A lot of new Trailblazers hit level 20 or 30 and can’t find the mode anywhere, though, so it’s normal to be confused about how to get Forgotten Hall Honkai Star Rail. This guide pulls from hundreds of hours of playtime across multiple accounts to walk you through every step of unlocking, accessing, and clearing the mode for all its best rewards, no fancy limited 5-star characters required.
Prerequisites to Unlock Forgotten Hall Honkai Star Rail
You can’t access Forgotten Hall as soon as you start the game, and you won’t get a pop-up notification for it the second you meet the requirements either. You’ll need to hit three non-negotiable milestones first, all of which are easy to hit if you follow the main story path and complete daily training tasks for the first two weeks of play.
- Trailblaze Level 24 or higher: You can farm extra EXP by completing Calyxes, side quests, and daily training if you’re a few levels short and eager to unlock the mode fast.
- Complete the Jarilo-VI main story quest "Lingering Shadows: Act 2, A Star in Search of a Voice": This is the point where you finish the core story for the first major planet after Herta Space Station, so you can’t skip this step even if you grind levels nonstop.
- Clear the introductory "Path of Oblivion" tutorial quest: This short 2-floor quest unlocks automatically after you hit the two above requirements, and you can find it in your daily mission tab when it’s available.
A lot of players get stuck waiting for the tutorial quest to pop up, so don’t panic if you hit level 24 and don’t see it immediately. Restart your game once you’ve confirmed you finished the required story quest, and it should show up in your mission list right away. You don’t need to spend any Stellar Jades or special items to unlock the mode, so you won’t have to dip into your limited pull currency for access.
How to Access Forgotten Hall After Unlocking It
Once you finish the introductory tutorial quest, Forgotten Hall will be permanently added to your game interface, but it’s not super obvious where to find it if you don’t know where to look. You won’t see it on the main open world map, and it’s not listed under the "Survival Index" tab with Calyxes and Caverns of Corrosion either.
To get to it fast, open your main menu and tap the "Interastral Guide" icon on the right side of the screen. Look for the purple icon shaped like a broken hall with a glowing border, labeled "Forgotten Hall", and tap it to teleport directly to the mode’s lobby. You can also add a shortcut to your main screen’s quick menu if you plan to run it often, which saves you a few taps every time you want to clear new floors for rewards.
It’s important to note that Forgotten Hall resets every two weeks on Monday at 4 AM server time, so you’ll want to make a habit of checking back every reset to claim new rewards. The first 15 floors are permanent and only give rewards once, but the rotating last two floors (called the Memory of Chaos stages) give fresh Stellar Jades, relic xp, and credits every single reset for as long as you can clear them. Even if you can only clear half the rotating stages each cycle, you’ll still get a steady stream of useful materials for your account.
Beginner Tips to Clear Early Forgotten Hall Floors Fast
Unlocking Forgotten Hall is only half the battle, and a lot of new players jump in right after unlocking and get wiped on the third or fourth floor because they don’t know how the mode’s unique rules work. Unlike regular open world combat, Forgotten Hall has stage-specific buffs and requirements that reward team composition flexibility more than raw character power.
First, always pay attention to the weakness type requirements listed at the top of every floor. Most early floors have three or more enemy types with specific weaknesses, so you’ll want to bring at least one character of each matching weakness type to break shields fast. You don’t need 5-star characters for early floors either: 4-star units like Dan Heng, Serval, and March 7th are more than strong enough to clear all 15 permanent floors if built even decently.
You also get a bonus score for clearing floors in as few cycles as possible, so don’t be afraid to swap out your healer for an extra damage dealer if you’re not taking much damage. The mode doesn’t penalize you for losing characters as long as you finish the stage, so you can play aggressively to hit the cycle limit and get the maximum star rating for extra rewards. But if you’re struggling to stay alive, running two sustain units (like Natasha plus March 7th) is always a safe call, even if it takes you an extra cycle to clear the floor.
For the first 10 permanent floors, you don’t need to worry about splitting your team into two separate squads. That rule only kicks in at floor 11, so you can focus on building one strong core team until you hit that point. A lot of new players waste resources leveling up eight different characters too early, which makes the first 10 floors way harder than they need to be.
Best Rewards You Can Get From Forgotten Hall
It’s worth putting in the time to unlock and clear Forgotten Hall as soon as you hit the requirements, because it’s one of the only consistent free sources of Stellar Jades in the game outside of event rewards and main story quests. Even if you only clear the first 10 permanent floors, you’ll walk away with more than 2,000 Stellar Jades, enough for almost 13 pulls on any limited banner.
Other top rewards from permanent floors include Self-Modeling Resins, which let you pick the exact main stat of any relic you craft, a super rare item that’s almost impossible to get anywhere else. You also get tons of relic XP materials, credits, and even a free 4-star light cone for clearing floor 15 for the first time.
The rotating Memory of Chaos floors give even better rewards for repeat clears, with up to 600 Stellar Jades available every two weeks if you can clear all 10 stages with full stars. That adds up to 1200 Stellar Jades a month, almost enough for a full 10-pull every month without doing any other content. You also get extra materials to level up your light cones and traces, which cuts down on the grind you need to do in Calyxes every week.
You don’t have to clear every floor to get value from the mode either. Even if you only clear the first three Memory of Chaos stages every reset, you’ll still get 180 Stellar Jades and a pile of useful materials for almost no effort. Don’t feel pressured to clear every single stage right away, especially if you’re still building up your second team for the higher floors.
You don’t need to be a high-spending whale or have a full roster of 5-star characters to unlock and get value out of the mode, so don’t put off working on the prerequisites if you’re still leveling up your Trailblaze level. Once you know how to get Forgotten Hall Honkai Star Rail, it becomes one of the most reliable ways to stock up on pull currency and upgrade materials to make your account stronger over time. Take it one floor at a time, focus on matching enemy weaknesses, and you’ll be clearing even the hardest Memory of Chaos stages before you know it.
