After the fimbl falls during Reaching the Far Shore, the way forward is to let the lake change and then walk across the ice to a cave on the southern shore. No message announces the change, and the frozen part of the lake lies off the shore by the Deserted Lakeside Estate.
Quick answer: After the fimbl falls the task moves on in steps; back at the lake, go to the Deserted Lakeside Estate shore. The task updates to “Cross the lake and retrieve the treatise.” Walk east across the ice, round the fimbl’s remains on the west, then follow the ice strip south to the cave.
How the task moves from waiting to crossing
When the fimbl is felled, the banner reads “Reaching the Far Shore” / “You felled the ferocious fimbl.” and the task becomes “Wait for the change to come over the lake.” In Quest Details the line reads: “Now that the fimbl lies defeated on the lakeshore, all that remains is to wait for this “peculiar effect” to take place.”
Resting at a camp with “Await Weather Change” at the campfire ring in Ettam Forest changed the weather, but the lake stayed open water and the task did not advance. The next step showed on arriving back at the Norgandian Settlement, as a banner: “Reaching the Far Shore” / “Confirm that the change has come over the lake.”
Jiera, if asked in the settlement, explains that you simply wait a while and then head back to the lake to see the change, and reminds you of the treatise in the cavern on the southern shore. No new task line comes from her.
Two nights’ rest at the Norgandian Inn produced no notification or banner, and the task line stayed “Confirm that the change has come over the lake.” Do not wait for a message telling you the lake has frozen.

The frozen part of the lake sits off the estate shore on the west side. Seen from the beached boats on the eastern shore, the lake was still open water.
Go to the Deserted Lakeside Estate with its ballista platforms. On reaching that shore, the task line becomes “Cross the lake and retrieve the treatise.” in the Pause Menu’s quest panel. No banner appears for this change.
From the estate shore, broken floes and broad, level ice sheets cover the lake, with patches of open water between some sheets. A stone ruin is visible in the middle distance, while cliffs frame the right side.

The fimbl’s frozen body stretches across the ice; its long white neck and tail curve overhead, studded with crystal spines.

The route across the frozen lake
Stepping off the ballista platform’s edge drops the Arisen into the open water, where the Brine (a red glow) takes hold and puts him back on the shore.


Keep along it until you reach the shore rocks.

The task line stays “Cross the lake and retrieve the treatise.” as you reach it.
What the fimbl’s frozen remains give you
Beside the remains on the ice, the prompt “F Examine” appears.

Holding F takes four items at once:
- “Spoils: Lv 3, Ancient Light Weaponry”
- “Spoils: Lv 3, Ancient Long Weaponry”
- “Spoils: Lv 3, Ancient Bowstaff”
- “Wintry Dragon Scale”
A second hold of F gives nothing more.

With the items collected and the body passed on its west side, follow the ice strip south and step into the cave to continue toward the treatise.
