Logically, this means
16% fail, nothing happens
But Nexon could have typed it wrong and it really means
What I want to know is
1. How does it work in KMS?
2. Does anyone have proof or reliable source of using an epic potential scroll in GMS and it failing and the item not booming
3. If the 16% fail does happen, does anything else happen besides losing the scroll?
4. For clarification purposes, these scrolls can be used on 'rare' items and 'non-potentialed' items correct?
