What is the Obsidian Spear, and what’s it used for?
Want to create a truly vicious weapon in Green Hell? Take one of the world’s sharpest materials, shape it into a blade, and tie it to a spear. The Obsidian Spear is one of the strongest weapons in the game in terms of raw damage.
This guide will walk you through how to craft an Obsidian Spear and offer some tips on how it can best be used.
How to craft an Obsidian Spear in Green Hell

Obsidian is moderately rare and can be quite difficult to acquire for players who don’t know where to look.
Before planning to craft this weapon, make sure you can source the following materials:
- 1 Long Stick
- 1 Rope
- 1 Obsidian Stone
Long Sticks can be collected by chopping down trees with a tool such as an Axe or Stone Blade. Rope can be gathered by collecting Liana vines hanging from large trees. Obsidian Stones can occasionally be found inside or near the entrances to caves.
Once you’ve collected the proper materials, craft the Obsidian Spear by:
- Opening the radial menu (by holding the
C
key) - Select crafting from the options
- Drag the rope, long stick, and obsidian stone to the crafting rock from the backpack or environment
- Press the craft button above the crafting rock
Note: The crafting menu can also be opened from the inventory sidebar or by holding the alt-select button (default RMB
) over one of the ingredients and pressing craft.
How to equip the Obsidian Spear

The Obsidian Spear can be found in the tools tab of the inventory and occupies one of the four standard tool slots (numbered 1-4). It can be equipped at any time by pressing the number key corresponding to the slot this tool occupies.
Tips and tricks for using the Obsidian Spear



The Obsidian Spear is specialized for mid-game combat and hunting. Though overall quite powerful, this spear suffers from a severe handicap in terms of its reach.
These spears are incredibly deadly, easily outclassing Weak Spears, Stone Spears, and Bone Spears.
Every spear in the game has a unique attack range based on its construction. Unfortunately, the Obsidian Spear offers the shortest range for basic and power attacks among all spear types. This can make hunting and combat more dangerous and more difficult.
The Obsidian Spear is still a remarkably effective close-range weapon in combat, killing most enemies in 2-3 hits. If you want to use this spear’s power without increasing your risk of injury in combat, try using it as a throwing weapon. When thrown, it can kill or severely cripple its target in a single hit.
When facing other spear fighters, dodge to the side and remain mobile, circling around your opponent and striking from an angle to prevent their superior reach from driving you back.
It is typically a good idea to refrain from crafting these tools until your crafting skill is at least mid-level to avoid wasting rare materials on tools that will quickly break.
Currently, no obsidian tools have their own notebook entry.
Final thoughts on the Obsidian Spear
Creepy Jar figured that if a player could sharpen a rock for a spear-point, it was only natural for them to be able to do the same with obsidian. Though this weapon is riskier overall, its impressive damage value and ranged ability make it a considerable threat to angry natives and predators everywhere.
