Day Of The Assault: Noon

Trial By Fire

After the cutscene ends, quickly use Quen, which helps mitigate damage from the dragon’s fire. To pass through the area safely, make sure you stick by King Foltest and Triss as they enter the tunnel to the left side of the bridge. Stay as far to the left as you can, as the dragon’s fire can damage you through the right side of the tunnel wall when it sweeps over. There are La Valette soldiers to fight here and some may be heavily armored.

Running past them isn’t a good idea because they’ll follow you. Just keep Quen up and patiently take them out one by one. Foltest, Roche, and Triss will help you. Once you reach the end of one tunnel, pass into the second, then fight the handful of enemies beyond. When Triss freezes the collapsing arch above you, continue forward. Run as quickly as possible across the burning bridge. If you make it through all this without being killed, then you’ve cleared the quest.
