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!

 - 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
