Updated June 03, 2025 by Mina Smith:Genshin Impact’s Dragontooth Spear is a powerful, free weapon that doesn’t require Wishes to get. This is great for many players who are looking to avoid or can’t afford to spend real money on this free-to-play Gacha game, even though it does take a lot of time. In order to complete both the Festering Fang quest and get that Dragontooth Spear made and fully refined, this article has been updated to include more information on respawn times, more maps, and clearer instructions to make sure anyone who wants this epic spear can make one (and fully upgrade one) for themselves.
Four Strange Tooth Locations in Genshin Impact
To get right to it, the four Strange Teeth inGenshin Impactare all located inDragonspine, with three of them situated in the northern portion of the region and one to the southeast. Rather than attempt to describe these locations, a marked map is perhaps the easiest way to communicate the positions of the Strange Teeth, and one can be found below. Additionally, there are further details on each location following the map, which should alleviate any confusion.

Other Items for the Festering Fang Quest
As previously mentioned, Strange Teeth are not the only items that players will need to collect for this quest, as they will also need to obtain aNorthlander Polearm Prototype inGenshin Impact. This prototype can be earned in the Spiral Abyss or by leveling up the Frostbearing Tree, and indeed it plays a major role in the construction of the Dragonspine Spear.
Furthermore, players must collect a reasonable quantity ofStarsilver Orefor this quest, and the northern perimeter of Dragonspine is perhaps the easiest place to find it. Indeed, the beaches in that area are home to a number ofStarsilverdeposits, and fans that visit them should have little trouble getting all of the ore that they need. That said, the resource is certainly not exclusive to north Dragonspine, as players can find it scattered across the region.
How to Complete The Strange Tooth / Festering Fang Quest
After collecting all of these items, players will be instructed to fill one of the Strange Teeth with vitality, and that requires a return trip to location 3 from the Strange Tooth map above. This time around,Genshin Impactfanswill find themselves in battle with several Fatui, and they will receive theVitalized Dragontoothonce they have proven victorious. All that is left to do from there is return to Orban, hand over the items, and collect the rewards.
Getting More Strange Tooth and Vitalized Dragontooth
Players will need to collect severalmore Strange Teeth and Vitalized Dragonteethin order to fully refine their Dragontooth Spear; thankfully the teeth respawn in each of these four locations every two days or so. This will help to collect more teeth and get players every closer to the fully-realized Dragontooth Spear.
