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 simultaneously 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.

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.
