The information that I have regarding this card is that it is indeed a RNG to get it. The card from the market day actually pictures the same Bereskarn image that is in the hunting page. The card is labelled "A Terror in the woods".
Here is the information that I have.
It requires an extra action to begin the Bereskarn hunt.
Activating the Market Day card gives you +1 Bereskarn, and 10 clues.
It uses the +1 Bereskarn to begin the hunt which means if you fail, you will need to hope for another Market Day to give you the card again.
I sacrificed the element of surprise during the hunt.
The challenge for me required Derring-do.
I was a scholar.
My Derring-do = 34 + 20, gave me a 46% chance.
I succeeded, giving me 3 trophies, 10 dignity.
Here is the final fight with the Bereskarn:
SPOILERS!!
Ready your spear It will be a difficult fight.
A brief clash. You are ready, your spear set. The beast charges full onto it, impaling itself in its frenzy. Its claws tear gouts of mossy soil from the forest floor. Its lifeblood pumps onto your boots. Its jaws clash, but you grit your teeth, tighten your grip and keep them at bay. When they fall still you draw a knife and claim the head and spines as trophies.
Derring-Do is increasing... You succeeded in a Derring-Do challenge! (Risky challenges mean you learn more.) [?]
You've gained 3 x Trophies (new total 11).
You've gained 10 x Dignity (new total 96 - Magnificent).
