I killed a level 26 mob and I got my first DragonBall the four star DragonBall, but when I keep killing the same level 26 mobs with the icon they won't drop it. Does that only mean they might drop it? Or does it mean that I probably need to kill a different mob?

5% chance to get a dragonball from DB monster.

Thank you. I was worried I wouldn't be able to get anymore DragonBalls.

Woah, 5% chance? I thought it meant if you killed it, then it would have to drop a dragonball...

i bealive the chance are even lower than 5%
