Lightning Strikes Twice is a Chaos++ boss quest in Granblue Fantasy: Relink – Endless Ragnarok that tasks you with taking down the Dawncrasher Whitewyrm on the Ainsteddo Archipelago East island. It sits at the top end of the endgame difficulty ladder and rewards the Celestial Ventus V+ sigil on your first clear.
Quick answer: Defeat the Dawncrasher Whitewyrm within the 60-minute limit without letting the critical gauge hit 0. The quest unlocks after you complete all Chaos+ Key Quests, and it needs a recommended Power of 32000.

Requirements to unlock and start the quest
The quest appears at the Quest Counter only after you clear every Chaos+ Key Quest. Once it is available, check your party Power before queuing, since the fight is tuned for a high-end roster.

Completing Lightning Strikes Twice for the first time grants the Celestial Ventus V+ sigil. This is a guaranteed one-time reward tied to your initial clear.

Side goals and their rewards
Each optional objective pays out its own item on top of the standard clear rewards. The 12-minute goal is the tightest and hands over the Whitewyrm’s Jewel.
| Side Goal | Reward |
|---|---|
| Clear within 12 minutes | Whitewyrm’s Jewel |
| Destroy all destructible parts | To be confirmed |
| Don’t enter critical condition too often | Daybreak Merit |
Material and sigil drops
Repeating the quest can yield high-tier upgrade materials alongside another chance at the featured sigil. These drops are not guaranteed on every run.
| Drop | Type |
|---|---|
| Grand Refinium III | Material |
| Primordial Light | Material |
| Celestial Ventus V+ | Sigil |

How to confirm the quest is done
The run counts as cleared once the Dawncrasher Whitewyrm is defeated inside the 60-minute window. If the critical gauge drops to 0 before that, the quest fails and no rewards are given, so prioritise survival and avoid repeated critical conditions if you want the Daybreak Merit goal as well.
For the fastest reward chase, aim for the sub-12-minute clear to secure the Whitewyrm’s Jewel, then continue running the quest for Grand Refinium III, Primordial Light, and repeat Celestial Ventus V+ drops.
