Flavor Blast! is a Chaos++ survival quest added with the Endless Ragnarok expansion for Granblue Fantasy: Relink. It drops you into a timed fight where the only goal is to clear out as many enemies as possible before the clock runs down, and it becomes available once you have pushed deep into the endgame quest ladder.
Quick answer: Complete the Lightning Strikes Twice Chaos++ Rank Up Quest to unlock Flavor Blast!, then survive the four-minute run on Phondam, the Scarred Isles by defeating foes without letting the critical gauge drop to 0.

Flavor Blast! quest details
The recommended power of 32000 reflects its Chaos++ ranking, the highest difficulty tier in the game. As a survival quest, there is no single boss to burn down. Instead, your score comes from clearing waves of enemies while keeping the critical gauge alive.

Flavor Blast! is one of the Chaos++ Key Quests, so it only appears after you have progressed the Endless Ragnarok storyline into that tier. The direct requirement is finishing the Lightning Strikes Twice Chaos++ Rank Up Quest at the Quest Counter.
Reaching Chaos++ itself follows a long chain of the expansion story. You first promote to Fatebreaker, clear the Chaos and Chaos+ Key Quest sets, and eventually reach the Weight of a Blade Chaos++ Rank-Up quest, which opens the full Chaos++ Key Quest lineup that Flavor Blast! belongs to.

Side goal rewards
Because this is a survival run, the payout scales with how many enemies you take down inside the time limit. The confirmed side goals track Lavashell kills and a single Aces High target.
| Side Goal | Reward |
|---|---|
| Defeat Lavashell x80 | Glittercrystal Cluster |
| Defeat Lavashell x150 | To be confirmed |
| Defeat Aces High x1 | To be confirmed |
Material drops
Grand Refinium III is a possible material drop from Flavor Blast!, which makes it a useful farming target for late-game weapon and sigil upgrades. First-clear rewards and any additional sigil drops are still being confirmed.

Avoiding the fail condition
The run ends in failure the moment the critical gauge hits 0, so managing that meter matters more than raw damage. Keep pressure on the incoming Lavashell waves to feed the gauge, and clear the four-minute timer with the gauge still above zero to bank your clear and any side goals you completed.
Note: Aim for the Lavashell x80 threshold early if you want the Glittercrystal Cluster, since survival quests lock in a side goal as soon as its kill count is met rather than at the very end of the run.
Because Flavor Blast! sits at the top of the Chaos++ Key Quest list, it pairs well with the other endgame farming targets on Phondam, the Scarred Isles, once your party is comfortably above the 32000 recommended power.
