Artifacts are story-related, or "key", items in UnderMine. Their discovery progresses the game's storyline in a certain way, like unlocking certain NPC shopkeepers in the Hub. They are not lost on death.
Equipment upgrades are persistent items that are purchased from NPC's. These items govern the player's five basic stats: Max Health, Swing Damage, Throw Damage, Bomb Damage, and Gold Integrity. Apart from these, one upgrade increases the throw distance of your pickaxe. These items are reflected under the Peasant tab in the Journal.
Food are consumable items that restore a certain amount of hp to the peasant when you collect them by running over it.
