BDO Cron Stone Chart & Guide

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
