This guide will be interesting to anyone who wants to get a 4-star weapon called Dragonspine Spear. It can be obtained during the "Decaying Fang" world quest. The quest involves searching for dragon fangs. 

The guide is dedicated to a detailed description of how to find and obtain the spear in the game Genshin Impact.

Starting the "Decaying Fang" Mission

Head straight to Dragonspine. Along the way, you will come across a white fang, pick it up. After picking it up, Paimon will recommend you to return to camp, saying that you will hear a story about the fang.

In the camp, you need to find a character named Yuexiao, who loves adventures. After talking to her, you will be sent to Orban, talk to him as well. You will be told to go and find at least three more of such fangs.

Locations of Unusual Fangs

The location of the first one is not so obvious. It is located in the corner of the map near Springvale. You can find it inside the ice crystal. You will need a crimson quartz to break it.

You can find the second fang on your mini-map. When you arrive there, you will see bones or fangs visible from the ground. Pick up all that you can find.

Head to the Frostbearing Tree to get the next fang. Before picking up the fang, you will have to defeat a guard. The crimson quartz will enhance your chances and make you stronger.

Activate the Dragon Fang

When you have 50 silver points and the required number of fangs, go to Orban and start a dialogue with him. Orban will send your character straight to the Dragonspine Core. Upon arrival, 3 Fatui enemies (Electro, Anemo, and Pyro) will appear before you. It is advisable to bring characters who can break Fatui shields. If you don't have that option, stock up on crimson quartz.

Defeated the enemies? Run to the core and start interacting with it. As a result, you will be captured by 8 more Fatui, and they will appear in waves.

Crafting the Dragonspine Spear

After defeating all the enemies, go to Orban and hand over all the required elements to craft the spear. An analog of the spear is obtained from the dragon Dvalin.

After completing the quest, you will receive the long-awaited 4-star weapon, as well as its blueprint. 

The ability increases the chance of a crystal appearing above the enemy's head during any attack. The crystal acts as additional damage and deals decent damage. Enemies with Cryo take 200% damage from the crystal.
