According to the planetcrafter.th.gl database, Planet Crafter obsidian comes from Resource Veins on Prime, Humble and Toxicity, mined with the T2 or T3 Ore Extractor. You need it late in the game for nine recipes, from the T6 Backpack to the Teleporter.
This guide covers where to find it, which extractor mines it, which recipes use it and how much you need to craft every recipe once. The English names come from planetcrafter.th.gl, which pulls its data from the game files.
๐ชจ What Planet Crafter Obsidian Is
It's a raw resource, not an intermediate product, so you can't craft it. The database lists 458 locations and names only three worlds. It lists no veins for Selenea, Aqualis and Skeo. If you're heading to Selenea or Skeo, pack a stock before you fly. What comes along when you switch planets is in our guide to traveling to a new planet.
Unlike Iron or Titanium, Planet Crafter obsidian only shows up in recipes late. Of the recipes with a known unlock value, the Teleporter comes earliest at 25 GTi, and the rest come much later. If you find loose chunks early, just put them in storage.
๐ Planet Crafter Obsidian Locations
The planetcrafter.th.gl database names Resource Veins on Prime, Humble and Toxicity as the source. Its interactive map shows the individual spots. The item page doesn't give an area name for the veins.
๐ Prime: The Lava Pits in the Southeast
For Prime, a TechRaptor guide from April 2024 (game version 1.0) names the Lava Pits in the southeast of the map, at coordinates -898:87:-305.
According to the guide, you place the extractor on the darkened sand there. The same area also has loose chunks of the rock and Iridium. That's a claim from a gaming site, not from the game data.
TechRaptor says this is the only natural source the author found on Prime. The database also names Humble and Toxicity. The Lava Pits tip doesn't apply there, so use the interactive map for those worlds.
โ๏ธ Which Ore Extractor Mines Planet Crafter Obsidian
According to planetcrafter.th.gl, only two buildings produce the resource: the T2 Ore Extractor and the T3 Ore Extractor. The basic Ore Extractor isn't on the list. TechRaptor only talks about the Ore Extractor in general, without a tier. So plan with the T2.
| Building | Recipe | Unlock |
|---|---|---|
| T2 Ore Extractor | 3 Osmium, 1 Super Alloy Rod, 2 Iridium Rod | 364.5 mPa pressure |
| T3 Ore Extractor | 1 Osmium Rod, 1 Super Alloy Rod, 1 Iridium Rod, 3 Titanium | 11.11 Pa pressure |
The T3 Ore Extractor is the more flexible one. According to the database, you pick the ore yourself. On tier 1 and tier 2 ore veins, you can also choose from the full list of 20 resources, obsidian included. How to get Osmium and the Osmium Rod is in our Planet Crafter Osmium guide.
๐ ๏ธ Prep Work: What the T2 Ore Extractor Costs
Before the first vein runs, you have to build the T2 Ore Extractor. According to planetcrafter.th.gl, it takes 3 Osmium, 1 Super Alloy Rod and 2 Iridium Rods. One Iridium Rod is made from 9 Iridium, so the two rods cost 18 Iridium that you should have ready before you build. Where to find it is in the Planet Crafter Iridium guide.
The Super Alloy Rod is the second bottleneck. According to the database, it's made from Aluminum and Super Alloy at the Advanced Craft Station. How to get Super Alloy is in the Planet Crafter Super Alloy guide. If you stock both ahead of time, you can place the extractor right after it unlocks at 364.5 mPa.
For the T3 Ore Extractor the math changes: instead of 3 Osmium and 2 Iridium Rods, it wants one Osmium Rod, one Iridium Rod, one Super Alloy Rod and 3 Titanium. According to the database, the Osmium Rod is made from 9 Osmium. So the T3 costs more Osmium, but only half as much Iridium as the T2.
โ๏ธ Every Recipe With Planet Crafter Obsidian
The item page lists nine recipes that use Planet Crafter obsidian. In our spot checks, planetcrafter.th.gl only showed amounts of two or more, such as 2 Pulsar Quartz for the Teleporter or 3 Obsidian for the T2 Machine Optimizer. Where no number is shown, we count one.
| Recipe | Amount | Other ingredients | Station |
|---|---|---|---|
| T6 Backpack | 1 | Blazar Quartz, T5 Backpack, Magnetar Quartz, Circuit board | Advanced Craft Station |
| Cosmic Quartz | 1 | Magnetar Quartz, Blazar Quartz, Pulsar Quartz, Quasar Quartz, Solar Quartz, Zeolite, Osmium, Nitrogen cartridge | Quartz craft station |
| Solar Quartz | 1 | Nitrogen cartridge, Sulfur | Biolab or Quartz craft station |
| Fusion Energy Cell | 1 | 3 Pulsar Quartz, 2 Osmium | Advanced Craft Station |
| Vehicle โ T2 Equipment increase | 1 | 2 Vehicle โ T1 Equipment increase, Super Alloy | Vehicle station |
| Extraction rocket | 1 | Super Alloy Rod, Rocket Engine, Osmium Rod, Blazar Quartz, Solar Quartz | Extraction platform |
| Microchip โ Map | 1 | 2 Aluminum | T2 Craft Station |
| Teleporter | 1 | Super Alloy Rod, Osmium, Zeolite, 2 Pulsar Quartz | Multitool (build mode) |
| T2 Machine Optimizer | 3 | 2 Explosive Powder, Uranium Rod | Multitool (build mode) |
The unlock values planetcrafter.th.gl gives: Teleporter at 25 GTi, Fusion Energy Cell at 38 GTi, T6 Backpack at 350 GTi and T2 Machine Optimizer at 1.85 mK heat. For the other recipes, the database shows no value on the item page.
๐งฎ Our Math: 13 Obsidian to Craft Every Recipe Once
If you just add up the nine recipes, you get 11. That's too low, because Solar Quartz contains one itself. Cosmic Quartz and the Extraction rocket each need a Solar Quartz, so both hide a second piece. That means crafting each of the nine recipes once costs 13 Planet Crafter obsidian in total.
| Recipe | direct | via Solar Quartz | total |
|---|---|---|---|
| Cosmic Quartz | 1 | 1 | 2 |
| Extraction rocket | 1 | 1 | 2 |
| T2 Machine Optimizer | 3 | 0 | 3 |
| six other recipes | 1 each | 0 | 6 |
| Total | 13 |
That's the floor. Several Machine Optimizers, a second Teleporter or Fusion Energy Cells in bulk push the demand up fast. According to the database, the cell goes into six more builds, including the Drone station, the Portal generator and the Interplanetary travel rocket.
๐ The Cheapest Recipes First
Three recipes on the list need little beyond the rock itself. The Microchip โ Map only adds 2 Aluminum, and according to the database it lets you display the map from anywhere. The Vehicle โ T2 Equipment increase needs two T1 increases and one Super Alloy, and the database lists a value of 8 for its Equipment Increase. The Teleporter takes more material but unlocks as early as 25 GTi.
If you only have a few pieces of Planet Crafter obsidian from loose chunks, put them into these recipes first. The Fusion Energy Cell and the Extraction rocket tie up Osmium, Pulsar Quartz and rocket parts that you usually only have in bulk later.
๐ Where Planet Crafter Obsidian Hides in Other Recipes
Cosmic Quartz and Solar Quartz are ingredients themselves. According to planetcrafter.th.gl, Cosmic Quartz goes into the T7 Backpack, the Energy multiplier fuse and the Quartz craft station, among others. Solar Quartz also goes into the T2 Rocket Engine, the Energy multiplier fuse and the Interplanetary travel rocket. Which fuses exist and what they cost is in the Planet Crafter fuses guide.
So if you're working toward the last backpack and fuse tiers, you need Planet Crafter obsidian not just once but in every step that uses Cosmic Quartz. That's why a vein of your own with a T2 Ore Extractor pays off early, instead of hunting down every piece by hand.
๐ The T6 Backpack as Your First Goal
For many players, the T6 Backpack is the first reason to go looking. The database lists a Backpack Increase value of 33 for it. You also need Blazar Quartz, Magnetar Quartz, a Circuit board and the T5 Backpack. How the equipment tiers build on each other is in the Planet Crafter equipment guide.
๐ก Mining Tips
- Don't look for the extractor too early: the T2 Ore Extractor only unlocks at 364.5 mPa. Until then you're stuck with loose chunks, like the ones TechRaptor describes in the Lava Pits.
- Stock up before the moon trip: the database lists no veins on Selenea, Aqualis and Skeo.
- Pre-craft Solar Quartz: it goes into Cosmic Quartz and the Extraction rocket and uses up one piece of Planet Crafter obsidian every time.
- Place the T2 Machine Optimizer carefully: at 3 pieces, it's the most expensive recipe on the list.
