Pure Bladestone

Pure Bladestone is an Upgrade Material in Demon's Souls.


In-Game Description

Ore wet with dew. Enhances knives, curved swords, spears, and so on.
An ore used to make weapons that take skill to rend enemies. Weapons can be strengthened by Bladestones up to a maximum of level 5. Using bladestones to enhance a weapon can cause them to become brittle, so exercise caution.


  • Very rare drop from the Black Skeleton near the start of 4-1.
  • Very rare drop from the Black Skeleton hidden behind an illusory wall beyond the Adjudicator Archstone.
  • Rare drop from the Black Phantom Black Skeleton shortly before the last Reaper near the end of 4-2 (requires Pure Black World Tendency).
  • Since it's drop rate is so low, it is recommended to max out your rare item drop chance (since this is a rare drop), while making your common item drop as low as possible (since the common item drop chance will override the rare drop chances, making them lower). The luck stat will increase common item drop rate, while black world tendency will raise the rare item drop rate.

General Information[]

Pure Bladestone is required to upgrade +4 Sharp weapons to +5. It is one of the rarest items in the game. It can also be traded with Sparkly the Crow in the Demon's Soul's Remake for a Ring of Longevity.
