Failed foundry quest
The objective at the start of Room 5 is to save all three snakes, then kill the Black Beast. Once completed, you can accept the quest reward and the Fury will spawn in the middle of the room. Sometimes a snake may get stuck and cannot be rescued in time. Fortunately, there are situations where the run can still be saved.
Critical points:
The Backfire/MLK must not take the new quest in Room 5 (accepting the previous quest reward is fine). The quest can only be completed normally if all three snakes are alive together so you can trigger and kill the Beast. If Snake 1 dies before Snakes 2 and 3 are picked up, the zone becomes impossible to complete.
In all other situations, keeping General Yendzarsh alive is the top priority, since he is the only one who provides the quest reward that spawns the Fury and allows you to finish the zone.
If all three snakes are threatened at once (for example, if

If the General dies, the run is over. If the other two snakes die, the run can still be completed.
If a snake dies, kill the Beast so the remaining snakes leave the group window. This updates the quest and allows the reward to become available. You can then return to Tekliss to update the quest automatically, even if the "all snakes alive" requirement failed, and finally claim the reward from the General to spawn the Fury and complete the zone.
