Erda Spectrum is a party quest located near Vanishing Journey in the Arcane River area.
The purpose of the PQ is to help Nina conduct research on the Erda in the area, using an Erda Collector throughout the PQ. It will have a different function depending on the stage.
Within the Land of Oblivion
|Within the Land of Oblivion|
For the first stage, the Erda Collector will be in the center of the map. Happy, Raging, Sad, and Joyful will spawn, and each Erda defeated will charge the Collector by 1. Occasionally, a blue bubble will appear and burst, charging the Collector by 10 if you are standing in it. Pressing NPC chat near the Erda Collector will activate it, with its active duration based on how much Erda has been charged; every charge will give it 1 second, and it can be reactivated when the timer runs out. Once it is charged, it will shift between blue, red, and purple, and attacking it will produce Erda Clusters based on its current color.
On the left and right side will be a red field and a blue field (at random), and the Erda Clusters must be pushed to the same color side by pressing NPC chat near them. Occasionally, a puddle will appear and burst on the ground, destroying any Erda Clusters above. To pass this stage, you must obtain a total of 10 points by doing this; red and blue will give 1 point each, and purple will give 2 points. The next stage you are teleported to will be random, either Within the Vanishing Land or Within the Land of Tranquility.
Within the Vanishing Land
|Within the Vanishing Land|
For this stage, Stone, Blazing, and Soulful will spawn slowly, with the spawn rate gradually increasing. You will have to kill as many as you can for the next 2 minutes; if there are 50 monsters left alive, you will be kicked out and fail the run. Like the previous stage, every Erda you defeat will charge the Erda Collector by 1, and pressing NPC Chat near it will eliminate up to 15 monsters. Once this stage is complete, you will be taken to the Reward Stage.
Within the Land of Tranquility
|Within the Land of Tranquility|
For this stage, Arma's Followers will spawn normally, and two Arma Jrs will spawn from the caves on the sides of the map, slowly moving toward the center. If they successfully reach the center, you will be kicked out and fail the run. Like the previous stages, every one of Arma's Followers you defeat will charge the Erda Condenser by 1, and pressing NPC Chat near it will fire a laser that can be held down to push Arma Junior all the way back into the cave; do this 5 times in order to complete this stage and be taken to the Reward Stage.
|Temporary Investigation Base|
This stage serves to give your rewards. If you successfully complete the PQ, you will obtain EXP and Arcane Symbol: Vanishing Journey. If you fail, you will be given no rewards, but the run will not count toward your daily completions.
- When Chu Chu Island is completed, you will be able to immediately complete 1 run to receive the Symbols instantly.
- When Lachelein is completed, you will be able to immediately complete 2 runs to receive the Symbols instantly.
- Note that the EXP reward will NOT be given if you choose to immediately complete the run.
