The bestiary of the Witcher 3 is stuffed to the brim with so many weird wonders and creepy creatures, it's enough to make the Monster Hunter franchise throw down its oversized sword in submission.
And while CD Projekt RED focused heavily on the story aspect of these monsters; giving them intriguing questlines and sometimes heartbreaking backstories, some seem to exist solely to make Geralt severely rethink his career choices.
Not only that, a lot of these fights don't even take place during the main story, meaning that unless you obsessively visit every single notice board like a Sorceress on her child's PTA group, there's a good chance you've missed some of these challenging (and rewarding) bosses on your first playthrough.
Yet with the Witcher 3 recently celebrating its five year anniversary, there's never been a better time to blow the dust off those Samum bombs and jump into Geralt's leathery onesie once more. And armed with this list, you'll know all the best contracts, side quests and optional encounters to seek out when looking for the next trophy to slap on Roach.
Just make sure you pack your potions, yeah? You're certainly going to need them.
