It could keep the same style for the rewards, maybe just variations in the animal skins, perhaps new exclusive skins for other types of animals. One thing that couldn't be missing is a chest; as a veteran player, what I miss most is base space. I personally only suggested changes mainly for the ring, as it has a unique effect, making it unnecessary to use another one, and making more units of it useless.
Here's an idea for a ring or necklace that would be very, very useful, especially for me since I farm in the Swamps and Boreal areas, and even in the Rio Bravo area. It would be called "Force of Nature," and basically, the character would be invulnerable to debuffs caused by the nature of the maps, such as slowness in the Swamps, snow in the Boreal area, and the winds of the Rio Bravo (including the thorns in the old mine).
The main purpose of this item would be to greatly speed up farming in the Swamps and Boreal regions, where the character becomes very slow on certain occasions.
