Unique Quests

Trouble at the Plant

Client Rewards Affinity
Jarack 7700G, 4700 EXP, Shell Gauntlets, Good Footing II None

Jarack at the Ether Plant has explained to you that one of the wind turbines was attacked by Hodes and needs fixing! He also wants you to teach the Hodes a lesson so they might think twice about attacking again. This quest activates two other quests: Punish the Hodes and Mend the Plant. In order to proceed with and complete this quest, the other two quests must be completed.

Completing both Punish the Hodes and Mend the Plant will simultaenously complete this quest too. Following this quest, you will be forced to accept the surprise quest, Hode Attack.

Punish the Hodes

Client Rewards Affinity
Jarack None

This quest is received once you have activated Jarack’s quest, Trouble at the Plant. You must finish this quest in order to complete Trouble at the Plant. Jarack has asked you to teach the Hodes who attacked the Ether Plant a lesson. You must defeat Funeral Gozra at the Hode Refuge in Eryth Sea. Hode Refuge can be found east of the Ether Plant. If you jump off of the ledge where Jarack is found, you can swim to the island where Hode Refugee is located. Conveniently, all over the island you will find Hodes that you can farm the Luxury Hode Wood from that is required to complete Trouble at the Plant. Once you have fought your way through the barrage of Hodes, you will have to swim a short distance to a small alcove where you will find the level 42 Orluga-type unique monster, Funeral Gozra, who is flanked by several lower level Hodes. Once defeated, this quest will be completed.

The Funeral Gozra is the Leader of the Hodes in Eryth Sea.

Mend the Plant

Client Rewards Affinity
Jarack None

This quest is received once you have activated Jarack’s quest, Trouble at the Plant. You must finish this quest in order to complete Trouble at the Plant. Jarack needs you to find 3 Luxury Hode Planks so he can repair the wind turbine. These are dropped by Hodes across Eryth Sea, however, it is easiest to farm these at Hode Refuge since you must go there to defeat Funeral Gozra for the other quest required to finish Trouble at the Plant, Punish the Hodes. Once you have the required amount, return to Jarack, who will then ask you to repair the turbine for him. Head over to the furthest turbine on the right and press ‘A’ to repair. After repairing the turbine, return to Jarack to complete the quest. This will also simultaneously complete Trouble at the Plant.

Hode Attack

Client Rewards Affinity
Jarack 5400G, 3000 EXP, Buff Time Plus II, Divine Protect II None

Once you have completed Trouble at the Plant, the Hodes will lead a surprise attack against the Ether Plant, triggering the quest, Hode Attack. Jarack will run and hide beneath the plant, whilst you fight off 2 Confusion Ekidnos. Once defeated, return to Jarack to complete the quest.

The Confusion Ekidno are looking to avenge their leader.

Trouble at the Lighthouse

Client Rewards Affinity
Shalen 5700G, 3800 EXP, Nightglow Staff None

This quest is available to you once you have completed Hode Attack!. And you may only activate it with Melia as the lead. Shalen will ask you to defend the lighthouse when the monsters attack at night, whilst they repair the lights. Your task will be to defeat Decay Ekidnos near Syrath Lighthouse at night. They will be waiting at each balcony on the upper level of the lighthouse. When you have defeated them, return to Shalen to complete the quest.

Upon the completion of the quest, Melia will unlock her fourth skill branch, Reticence.

Quests Available After Completing the Events at Mechonis Core

These quests are available after you have witnessed the events at Mechonis Core. Some of these quests are given by NPCs who did not previously reside at Eryth Sea.

The Missing Boy

Client Rewards Affinity
Miriall 23000G, 48000 EXP, Ether Protect VI None

This quest can be picked up from Miriall who is now found at the Ether Plant. She will ask you to find Teelan. He can be found in Alcamoth on the First Floor, in the small alcove to the south. Once you have found Teelan, return to Miriall to complete the quest.

Secret Research

Client Reward Affinity
Teelan 41000G, 68000 EXP, Rex Helm None

This quest can be picked up once you have completed The Missing Boy. Teelan will tell you to collect the Telethia Research found in the Telethia Laboratory in the High Entia Tomb. To gain access into the Laboratory, you’ll need the High Entia Emblem, which is obtained by completing The Imperial Ceremony quest in Satorl Marsh. The Laboratory is east of the Ceremony Hall on the Ground Floor. Once inside the Laboratory, you’ll be faced with the formidable unique enemy, Furious Jozan, who will attack you if he hears you. This means you can sneak around him to reach the Telethia Research, but you’ll have to be extra stealthy. However, you choose to approach the Research, once you have picked it up, return to Teelan to complete the quest.

You can choose to fight or avoid Furious Jozan.

Investigating Satorl

Client Reward Affinity
Miriall 20000G, 42000 EXP, Poison Defence VI None

This quest can be picked up from Miriall at the Ether Plant so long as you have not already completed Talia’s Research. The quests themselves are identical, however, the EXP and rewards received for this quest are higher. You are tasked with defeating the Dogmatic Gogol near the Place of Judgement in Satorl Marsh. The Dogmatic Gogol is only Level 32, since it appears that the quest exclusive monster is identical to the one you fight in Talia’s Research. They have not scaled the enemy to suit your much higher level, therefore, defeating him will be far easier in this version of the quest. Once you have slain the enemy, talk to Talia who is nearby the Place of Judgement. Then, after that, you will need to talk to her again when she has returned to the Ether Plant at Eryth Sea, in order to complete the quest.

Ancient High Entia Mystery

Client Reward Affinity
Talia 59500G, 93000 EXP, Meteor Staff, Talent Boost V 2✰

You can pick this quest up after the events at Mechonis Core if you have completed Talia’s Research or Investigating Satorl. To continue with this quest, you’ll need to complete The Imperial Ceremony quest in Satorl Marsh, as you will need the High Entia Emblem during this quest. You will need it to unlock the seal at La Luz Church on Valak Mountain. When you open the seal, you’ll have to walk down a long tunnel until you reach a small cliff space. There, you will find the War God Statue that you need to examine. After doing so, head back to Talia at the Ether Plant to complete the quest.
