Well, if you want 5 star, just buy it, cuz when you craft it, its kinda hard to get 5 star....
To craft it at Clodagh you need:
5x Superior Iron ore
30x Obsidian
6x Harma Bone Necklace
2x Wild Berry
Obsidian is dropped by trolls in Hilder Forest, Harma bone necklace is dropped by Harma in Investigation, and Wild Berry drops in Hilder Forest ruins, and You should know about superior iron ore....
or or or, you can craft it with goldsmithing, need 290 proficiency xD
If you need anything else, let me know
