Hidden Conditions:
For the first part of the battle, you have to fight Krillin, and Piccolo. After a short moment, Vegeta will join the fray. You have to defeat all three of them within five minutes to trigger an extra fight with Frieza (1st Form) as a hidden condition. Additionally, while fighting Frieza, Vegeta and Piccolo will be revived and join the battle. Defeat the three of them to complete the quest and get a higher rank.
^same......like 6 times I've done it. No fight with frieza. Is it rando
I got it to work by waiting for vegeta before killing the other 2.
Here's what happened to me, finished every time in less than 4 mins. Tried 5 times with either one ally or solo n no frieza battle. Finally tried with 2 allies n finally got it. Idk if it helps, but that was my experience
I defeated everyone under five minutes no extra battle with revived enemies
