# Obsidian
A unique material that gives weapons and armor Fire-based modifiers; however, it gives the item the [Brittle](Brittle.md) Property (which makes for great arrows).
### Crafting Modifiers
Gives the following unique modifiers:
- **[Brittle](Brittle.md):** A guarantied mod on the item. If the weapon rolls a 1, it has a chance to break.|
- **[Deadly](Verum/Continents/Corvanis/Armory/Items/Definitions/Weapon%20Properties/Deadly.md):** Critical hits add an additional weapon die with such weapons.
- **Greater Deadly:** Unknown.
- **[Exploding](Exploding.md):** Critical hits explode, dealing 1d10 Fire damage in a 5 ft. Radius. The item has a chance to break just like [Brittle](Brittle.md).
- **[Ghost Fire](Verum/Continents/Corvanis/Armory/Crafting/Smithing/Properties/Masterwork%20Properties/Ghost%20Fire.md):** The weapon gains an additional 1d8 Fire or Necrotic damage.
### Arrow Properties
- **Shatter:** Arrows shatter on impact, dealing Area of Effect damage on a hit.
