So you’ve got the Mangkwan Heavy Spear Thrower, you’re ready to upgrade it… and now the game hits you with Blood Obsidian and Fang like it’s some kind of cosmic joke. Yeah — you’re not alone. A lot of players hit this exact wall and start wondering if they missed something important or if the game is just messing with them.
These two materials are easily some of the most confusing to track down in Avatar: Frontiers of Pandora, especially during or after the From the Ashes DLC, where progression isn’t always clearly explained. The good news? They do exist, they’re obtainable, and you’re probably closer than you think — even if it doesn’t feel like it right now.
Here’s exactly where to find them — no fluff, no guessing, and no wasted time.
Where to Find Blood Obsidian
Blood Obsidian isn’t a normal crafting resource you can just pick up off the ground or stumble across while exploring. It’s tied to specific enemies and locations, which is exactly why so many players think it’s bugged or missing entirely. In reality, it’s just a bit more selective about where it shows up.
🔹 Kill Mangkwan Enemies (Main Source)
Your best and most reliable source is Mangkwan enemies, especially the tougher or elite variants you’ll encounter in DLC areas.
- Not every Mangkwan drops Blood Obsidian
- Elite variants have a noticeably better drop chance
- You must manually loot the body — it won’t auto-collect
If you’re farming, focus on Mangkwan patrol routes and fully clear each encounter before moving on.
🔹 Check RDA Facilities and Secured Crates
Some RDA outposts in the From the Ashes areas contain Blood Obsidian hidden inside locked or secured containers. These are easy to miss, especially if you’re focused on completing objectives rather than fully exploring the area.
A lot of players end up short on Blood Obsidian because:
- They rushed through the mission objectives
- They didn’t open optional or side containers
- They cleared enemies but didn’t return to fully loot the area afterward
These secured crates don’t always stand out, and they’re often tucked into side rooms or restricted zones. If you’re missing just one piece of Blood Obsidian, this is almost always the reason. It’s worth revisiting cleared RDA facilities and double-checking every container before moving on.
🔹 Story Pickups (Easy to Miss)
A few pieces of Blood Obsidian appear naturally during certain story missions, usually placed along the main path or just slightly off to the side. If you were focused on objectives, combat, or simply moving quickly through the mission, it’s very easy to run right past them without realizing what you missed.
Unfortunately, these story-based pickups don’t always respawn once the mission is complete. That means if you didn’t grab them the first time, they may be gone for good unless you reload or revisit earlier saves. If you’re missing just one piece of Blood Obsidian, it’s worth retracing your steps through major story locations and carefully checking every corner before assuming it’s bugged.
Can Blood Obsidian Respawn?
Kind of — but not in every way you might expect. Mangkwan enemies can respawn, which means you can technically farm Blood Obsidian by revisiting areas where Mangkwan patrols appear. This makes them your most reliable renewable source, especially if you’re willing to do a bit of backtracking.
However, story-based containers and secured crates do not respawn once they’ve been looted. If you missed those during a mission, they won’t magically refill later. Because of that, the best method is to fast travel between Mangkwan-heavy zones, clear out patrols, loot everything, then move on to the next area. It’s not instant, but it’s currently the most consistent way to farm Blood Obsidian.
Where to Get Fang (Yes, This Part Confuses Everyone)
“Fang” isn’t a single universal item, which is where most of the confusion comes from. Instead, it’s a category that changes depending on the creature tied to your upgrade. That’s why some players swear they have a Fang, but the game still won’t accept it.
🔹 Step One: Check the Upgrade Menu
Open the Mangkwan Heavy Spear Thrower upgrade screen and hover over the Fang requirement. The game will tell you exactly which creature’s fang you need — no guessing required.
This step matters more than anything else. Different fangs look similar in your inventory, but only the correct one will count. Before you start hunting, always double-check this screen so you don’t waste time chasing the wrong creature.
🔹 Most Common Fang: Viperwolf Fang
For most players, the required item ends up being Viperwolf Fang, making it one of the easiest materials to farm once you know where to look. Viperwolves are fairly common enemies and appear throughout many forested and river-adjacent regions, especially outside heavily industrial areas.
They also respawn consistently, which makes farming them much less frustrating than rarer creatures. If your upgrade doesn’t specifically mention a unique or legendary creature, there’s a very good chance Viperwolf Fang is what you need. Take your time clearing nearby packs, loot every kill, and you should have what you need without much trouble.
🔹 Other Possible Fang Types
Depending on your progression in the game, you might be asked to collect a more specific or rarer fang instead of the usual Viperwolf Fang. In some cases, the upgrade will require a Stormglider Fang or a Thanator Fang, both of which are tied to specific biomes, encounters, or story progression.
These creatures don’t appear as frequently and usually require intentional hunting rather than casual exploration. Stormgliders tend to appear in open, high-altitude areas, while Thanators are typically tied to more dangerous regions or story-driven encounters. Because of this, these fangs can take significantly longer to obtain. Always double-check the upgrade menu so you know exactly which creature you’re hunting before heading out.
Fastest Farming Route (Recommended)
If you just want to get this done as quickly and painlessly as possible, this is the most efficient route to follow. Start by fast traveling to a Mangkwan-controlled zone, preferably one with multiple patrols close together. Clear out every Mangkwan enemy you see and make sure to loot all bodies before moving on.
Next, check any nearby RDA facilities for locked or secured containers, as these often hold extra materials. After that, hunt nearby wildlife to gather the required Fang, focusing on the creature listed in your upgrade menu. Once everything is cleared, fast travel to another Mangkwan-heavy area and repeat the process. This loop is currently the fastest and most reliable way to farm Blood Obsidian and Fang without wasting time.
Common Problems (And Fixes)
“I can’t find Blood Obsidian anywhere.”
This is one of the most common frustrations players run into. In most cases, it means you either missed a secured container inside an RDA facility or didn’t fully loot Mangkwan enemies after a fight. Blood Obsidian doesn’t always drop automatically, and it’s easy to overlook bodies or side rooms during combat-heavy sections. Go back through Mangkwan-controlled areas, slow down, and make sure every container and enemy is fully checked.
“I have a Fang but it’s not working.”
This usually means you have the wrong type of Fang. Not all fangs are interchangeable. Open the upgrade screen and double-check exactly which creature’s fang is required before continuing to hunt.
Wrapping up
If you just want the short version, here’s everything you need to know in one place. Blood Obsidian mainly comes from Mangkwan enemies and secured RDA crates, especially in From the Ashes areas. Make sure you fully loot enemies and explore side rooms, since it’s easy to miss. Fang, on the other hand, depends on the creature required by your upgrade — most players will need Viperwolf Fang, but some upgrades call for rarer creatures instead.
The fastest farming method is to rotate between Mangkwan patrol zones, clear everything, check nearby RDA facilities, then fast travel and repeat. Always double-check the upgrade menu before hunting so you don’t waste time collecting the wrong material.
