Cron Stones are used in BDO to protect an item during failed enhancement.

Without using Crons, weapons and armor of DUO grade or higher can decrease 1 level from failing enhancement. Accessories are destroyed and all materials are lost after failed Courser Awakening.

Anyone need a hug now? 🙁

But there’s hope with Cron Stones to the rescue!

  • Weapons and armors are protected from downgrading a level
  • Protects 50% of your materials on Courser Awakening failure.
  • Accessories have unique rules.
    • The accessory is not destroyed.
    • 60% chance the accessory will not degrade
    • 40% chance the accessory will downgrade a level
  • All Cron Stones used are destroyed regardless of enhancement success or failure
  • Failstacks do NOT increase on failures
  • Cron Stone amount required usually increases with item grade and enhancement level
