In this game, "ice caves" are useless, they do not give anything to the player, I personally went there a couple of times, gave up this stupid activity and stopped being interested in them, passing by. Obviously, the invention of caves in the form in which they are, is caused only by the extremely poor imagination of the creators of this game, who "drew" them simulated "violent activity in their work" in fact, without giving anything new to this game. Refractory medicine is made from cloudberries and barley from the plains, or in another way, without visiting the plains and looting at least one village of people from the plains where barley grows, you will not make a refractory medicine........however, I do not remember that I personally needed it in caves, on extremely improved with silver armor and weapons, all these caves are extremely easy to pass through .....well, the resources I extracted there for new armor are absolutely useless, due to the fact that silver armor and weapons are at least as better and more effective than them.
