The 'Harvestables' category is one of the four main categories of the Itempedia that is widely used by the community of the Frontier in order to fulfill multiple goals, the other being Fishes, Monster Drops, and Feathers. The major goals include the following:
- To continue the flow of the player's progression throughout their adventures
- To gather up gold (currency) in order to obtain other game features that are not given at the beginning
- To fulfill one of the four time-consuming tasks in order to complete the Collectus & The Itempedia Quests.
Unlike the other three categories, harvestables does not require any kind of tools or weapons in order to obtain some harvestables. It requires the player's capability to harvest by hovering their mouse clicker or finger and pressing the letter 'E' on their keyboard. Most harvestables is mainly centered on plants, but will also apply to some creatures and objects like The Object From Earth and Grateful Frog, harvestables that are not classified as plants. Different locations of the Frontier provide a variety of harvestables that can be easily obtainable or difficult to obtain and require the players to wait for their targeted harvestable(s).
