Upon entering the instance, you start at the orange spot. You will see Oscar NPC. The party leader must talk to the NPC to initiate the battle. All party members will be randomly split to the left side (blue box) and right (green box) of the map. There are 50 monsters per side. You must clear 47 monsters in order to unlock the portal (yellow). If the other side is not cleared, the portal will lead you to the other side. You can have your support party members not move and they will be safe until you finish clearing your side.
After defeating one side of monsters, there is a chance that Oscar will announce the following message: “...”. A Prime Corruption Root will spawn in the center corridor and you must kill it within 30 seconds. If you fail to kill it on time, the Prime Corruption Root will kill all party members on screen (15×15) and then Oscar will purify it (defeat it for you). The amount of Prime Corruption Root spawned depends on the difficulty level. Two or more can spawn at difficulty level 4 while up to five can spawn at difficulty level 10. In order to have an opportunity in defeating the Prime Corruption Root, both sides must be cleared simultaneously so that the party can reach the center corridor in time. Alternatively, the party can entirely avoid the monster without any penalties other than less rewards from Oscar.
Once both sides has been cleared, the portal will lead to the center corridor where you will meet with Oscar who will lead you to battle against Phantom Amdarais.
There is a 5% ~ 10% chance that instead of Phantom Amdarais, players would battle against Phantom Himmelmez. Some Skills & Mechanics may differ and you would have the opportunity to get her card.
