Time for something new! A handy NPC is being added to Penumbra Crystallis named Key Coleman, but he'll just got by Key after his initial introduction. His name is a huge reference to someone in particular, but I will let players figure that one out!
So, what is the purpose of Key? Well, he is going to analyze your treasure hunter rank whenever you talk to him. If he likes what he sees, he'll reward you with a special item. Basically, the more chests you open and items you find hidden away in barrels and pots, the more receptive Key will be towards you and will grant you better items. Think of his presence as a sort of treasure hunting mini game. Open X chests to receive an item from Key. Go back out into the world, open X chests (or find X number of items in general), return to Key, get another reward!
Have fun, treasure hunters!
