Celestial Harmony Quest

Description:

In this quest, the player must collect 7 artifacts (Heart of the Sky, Essence of the Wind, Ghost's Tear, Sun Brooch, Golden Crown, Trapped Lightning, Golden Horseshoe), which can be found in individual seals. After gathering all the artifacts, they need to be combined to create the Crystal of Celestial Harmony. The crystal can then be handed over to an NPC in the temple of any city, unlocking the ability to receive 7th Blessings from that NPC. This quest can be done solo.

Requirements:

Completed first mission in The Castle Quest by killing Executioner Arranz just to push the lever.
Atleast 300 level
Demonic Essences (1000x)
Giant Shimmering Pearl (2x diffrent colors)
Rope

Start from Edron and follow the maps:

1) Solar Seal - Sun Brooch:

Nothing special in this series, in the last room we have to kill all the monsters otherwise we can't enter the room with Sun Brooch.

2) Skyward Seal - Heart of the Sky:

Now that we have completed one seal, we can return to the NPC Zarathar, who will assign us two more missions. He can be found → Here.

Player: Hi
Zarathar: Hail, Player... The shadows whisper your name. You tread in a place where few dare to walk.
Player: mission
Zarathar: I see, you are searching for the artifacts to assemble the 'Crystal of Celestial Harmony' ...
Zarathar: I am the guardian of this sacred place, and I have access to two of the necessary artifacts ...
Zarathar: To obtain them, you must complete two missions for me.
Zarathar: The first mission is simple but dangerous: prove your strength by slaying 100 Dragon Wraths ...
Zarathar: Once you've completed this task, return to me and I will grant you access to the first artifact ...
Zarathar: Do you accept this challenge, Player?
Player: yes
Zarathar: Very well, Player ...
Zarathar: The Dragon Wraths dwell in the deeper caverns of this place. You will find them in the shadowed depths of the underground ...
Zarathar: You must eliminate 100 of them to prove your worth ...
Zarathar: Return to me once you have completed the task. I will then guide you to the first artifact.

He gave us the first mission (task) in which we have to defeat 100 Dragon Wrath.
After that we return to Zarathar and have a conversation:

Player: Hi
Zarathar: Hail, Player... The shadows whisper your name. You tread in a place where few dare to walk.
Player: mission
Zarathar: Impressive, Player. You have proven your strength by slaying the Dragon Wraths ...
Zarathar: You are indeed worthy of the artifacts I guard ...
Zarathar: Now, would you like me to teleport you to the first artifact, the 'Heart of the Sky'?
Player: yes

We will be teleported to the room with Heart of the Sky so take the quest.

3) Phantom Seal - Ghost's Tear:

We have another conversation with Zarathar to do another second mission:

Player: Hi
Zarathar: Hail, Silver Arrow... The shadows whisper your name. You tread in a place where few dare to walk.
Player: mission
Zarathar: Ah, Silver Arrow, you have proven your determination by defeating the Dragon Wraths ...
Zarathar: Now, for the next task: bring me 1000 Demonic Essences ...
Zarathar: Only then will I teleport you to the second artifact, the 'Ghost's Tear' ...
Zarathar: Return when you have the required essences, and I will open the path for you.
Player: demonic essence
Zarathar: Excellent work, Silver Arrow. You've gathered the Demonic Essences I asked for ...
Zarathar: You have now proven your dedication and strength ...
Zarathar: Shall I teleport you to the second artifact, the 'Ghost's Tear'?
Player: yes

At this point we will be teleported to another room with a reward, we take it and go further, look at the maps:
