Walkthrough
Time Limit: none

Talk to Commander Hibba Agip and Abidal to take the two quests to finish Surt. Then talk to Nidhoggr inside the cave and check the Yggdrasil lookalike to reserve and enter the dungeon.

Inside, talk to Ahat in upper center part of this room. Defeat the furious version of Valkyrie Morocc Incarnation and Ghost Morocc Incarnation. You will get Soul of Ahat and Soul of Shinaim. At top center of the room, put each soul into the orbs to open the door to central room. Surt in boy form will greet you, and a conversation will happen when Loki and Nidhoggr join in.

After that, a portal will appear to the left. Talking to Nidhoggr again will grant you a Nidhoggr mercenary.

In this room, kill the Brinaranea, who has 81m HP. Once killed, every party member must talk with Nidhoggr and a portal leading back to central room will appear.

Note: You may want to collect some Frost Crystals in Brinaranea's room to help with the upcoming battles.

Surt will talk again, then a portal on the right will be opened. In this room, kill Muspell Skoll. He has 55m HP and will inflict heat status. If you take some Frost Crystal with you, you will be cured. Once defeated, talk to Nidhoggr again and portal to central room will appear.

Surt in Adult Man form will talk and open portal at the top. In this room, you will fight Surt in Boy form. He has 80m HP. Be careful when fighting him; if a green text saying he is regenerating appear, you need to stop attacking or else he will regenerate back to his full HP.

Once his HP already halved, he will disappear and summon 2 Surts. Once defeated, the boy will reappear with only 20% HP left. Finish him this time and no need to worry since he doesn't regenerate again at this stage.

After defeat, Surt in Adult Man form will appear which you need to be defeated. He has 120m HP. Defeat him and then talk to Nidhoggr again and you will be transported back to Mors Cave.

Talk to Abidal in the Flame Basin again to get 1 Squad Prize for defeating Brinaranea and Muspell Skoll. Then talk to Commander Hibba Agip again to get 1 more Squad Prize defeating Surt.
