Overview
Applied Escapology is a Blood and Wine treasure hunt in Sansretour Marsh that begins on the isle where Toussaint Prison stands.
Walkthrough
A corpse on the west side of the isle carries an escape artist’s journal. Drink a Killer Whale potion and dive to find an underwater cave, where a skeleton holds a key. The next location is in the Valley of the Nine, at the lake where Geralt entered the ruins in Turn and Face the Strange. This time, swim into the underwater cave by the shore. The dive is long, so Killer Whale is almost essential. The chest waits at the far end of the tunnel, with plenty of other valuables around it.
