5. Sawmill - schowek Halla's cache
In Stonegarden you can find a mausoleum with four sarcophaguses with old heroes of Driftwood buried inside of them. Interacting with each of the sarcophaguses gives you a location of a cache with hero's equipment. When you interact with each of them, you will be attacked by the heroes. You can't underestimate them because each of the heroes will be resurrected twice. This means that each hero must be defeated three times.
After the fights you can go and search for their caches. Each one of them is hidden and in order to find them you need to have, at least, 17 Wits. Although the caches itself aren't protected, you can find out that in order to reach Vish's and Justinia's caches you will have to break through by using force. This quest ends when you find all caches.
Reward: 70480 experience points + content of the chests
