There are a handful of side quests you might miss out on if you perform certain actions or get too far in the story.

Deliverance 2 offer rewards like a free horse and special combat moves. Reuniting with Mutt and completing "The Blacksmith's Son" are essential early-game quests. Seek out Master Tomcat for combat training,

Deliverance 2, "Miri Fajta" is one of the earliest you can find, with multiple endings depending on your actions. This is also a much longer quest than some others, requiring you to interact with many characters and complete multiple steps.
