Forgotten Temple

Talk to Petra in order to access the Forgotten Temple.

You must submit either 18 or 30 seals within two hours or all the seals will be taken away from you.

If you kill the summoned Nidhoggr's Revenge, Petra will automatically warp you to Level 2, and there's no going back unless you use another character that hasn't killed Nidhoggr's Revenge.

Entrance Requirements
Forgotten Temple 1: None (PvP off - newbie friendly)

Forgotten Temple 2: Nidhoggr's Revenge flag (PvP on)

Forgotten Temple 3: Shell King flag (PvP on)

Forgotten Temple 4: Complete 30 Runs. You will be returned back to Level 3 after killing Sphinx (including taming it).

Petra Rewards
The Temple Quest (in general) lasts 2 hours. Then, it'll warp you out from the Temple and the Excavation Seals are removed from you if you have not submitted them to Petra by then.

Now, Petra sent you off into the Temple asking for a minimum of 18 Excavation Seals in order for her to compile a Volume. These Seals are only obtainable from Temple Seals (the crystal looking thing) and it's given at a random chance.

However, little did you know that Petra increases her rewards should you bring her more than 18 Excavation Seals, and on top of that, every 10 and 20 Completion, you will be given even more.
