Dragon Stone Alchemy

General

The Alchemist NPC lets you craft, upgrade and enhance Cor Draconis — powerful stones that grant permanent stat bonuses to your character.

  • Stones come in 6 types (Diamond, Ruby, Jade, Sapphire, Garnet, Onyx)
  • Each stone has a Class, Purity and Level that determine its power
  • Farm Cor Draconis (Rough) from Level 90+ Metin Stones or bosses
  • Stones can have 2–5 random bonuses depending on luck
  • Failed enhancements only reduce level by 1 — stones cannot be destroyed

Downgrade System

If you get an Exzellent stone with bad bonuses, don`t throw it away — downgrade it!

  • Use a Green Tear to convert 1 Exzellent stone back into 2x Brillant stones
  • Green Tear drops from Razador, Nemere or Ultra Chest
  • ⚠️ Green Tear must be in your inventory, not in Special Storage U
