There are quite a few quests in The Witcher 3. In fact: there are 309 in total. These are my top 30 favourites.
Having screwed-up the initial search, I then re-load and finally track the monster down to its cave.
You can see at the five minute mark that when I turn around, looking for Eskel, I don’t see him and realise I’ve run too far. Amateurish Witchering!
