🌀 How to Enter
Speak to Hugin inside the Memorial Dungeon Space to begin Old Glast Heim ( OGH ). Each character must complete OGH Easy Mode first before they can enter OGH Advanced Mode.
⚠️ Important Notes
You have 1 hour to complete the dungeon.
Party Leader who is already inside cannot invite other players to the party.
If you disconnect, your character will remain inside the dungeon.
WARNING!!! If you leave the dungeon manually, you won’t be able to re-enter.
This walkthrough showcases the OGH Advanced Mode. The OGH Easy Mode follows the same storyline, with the only difference in the rewards, which you can check out the details HERE!
Speak to Varmundt to begin the expedition. Remember — only the Party Leader can talk to the NPC to start the instance.
After starting the instance, move forward a bit and talk to Heinrich. Wait patiently until the conversation between Heinrich and Varmundt finishes before proceeding.
Once the dialogue ends, the portal on the left will open. Enter it and defeat all the monsters in the area until a message appears, telling you that you must rescue the survivors.
Speak to Altar Boy Domun to proceed to the next stage of the dungeon.
After that, the portal on the right will open. Enter the area and defeat all the monsters until a message appears, instructing you to rescue the second survivor.
Speak to Holgren the Destroyer to proceed to the next stage of the dungeon.
After that, the upper-right portal will open. Enter the area and defeat the monsters until a message appears announcing that Himmelmez has appeared.
Chase Himmelmez to the northern area, and prepare to face the Corrupted Soul — the first MVP boss of the dungeon.
After defeating the Corrupted Soul, talk to Varmundt to claim your rewards — Temporal Crystal and Coagulated Spell — and to unlock the second quest to defeat Amdarais.
Keep in mind — only party members who are within the same screen as the boss when it dies will have their quest marked as completed, allowing them to claim the rewards.
⚠️ Important: If you don’t complete the Amdarais quest, you won't receive any rewards after defeating him.
Proceed to the next room and wait until the dialogue between Heinrich and Varmundt finishes before continuing.
After that, the portal on the left will open. Enter the area and defeat several monsters until a message appears saying Evil forces are appearing in this area.
When the message appears, search the area and defeat the mini-boss named 1st Commander of Destruction lurking nearby.
After defeating the 1st Commander of Destruction, you can proceed to the next stage of the dungeon.
The portal on the right opened. Defeat several monsters inside until a message appears saying An evil presence has teleported into this area.
Search the area and defeat the mini-boss named 2nd Commander of Destruction. After that, you can proceed to the final stage, where Himmelmez is already waiting at the end of the corridor.
Enter the final room to confront Himmelmez. Be careful — along the way, you’ll encounter many Maggots emerging from the corpses scattered along the path. Wait until the dialogue between them finishes, and then the final boss, Amdarais, will appear.
Defeat Amdarais to complete your quest.
After defeating Amdarais, talk to Hugin to claim your rewards: 3pcs Temporal Crystal and 3pcs Coagulated Spell.
Keep in mind — only party members who are within the same screen as the boss when it dies will have their quest marked as completed, allowing them to claim the rewards.
Don’t leave the dungeon yet — there’s still a bonus reward you can claim! Return to 1st Room, then head to the garden area at the upper-right corner of the map.
Activate the lever on the garden statue to teleport to the Treasure Room.
Keep in mind — only party members who have completed the Amdarais quest can activate the lever and enter the Treasure Room.
Treasure Room
This is not a personal reward, but a shared reward among all party members — so be considerate and share fairly.
Congratulations! You've completed Old Glast Heim Memorial Dungeon.
Happy RO! ^_^ 💖
