Rarity

An item's rarity depends on the method obtained. Each method has its own grading system which separates items into the following categories:
 * Always
 * Common
 * Uncommon
 * Rare
 * Very Rare
 * Extremely Rare

Mob Drops
Killing mobs in the overworld have their own drop rates. The Hunt has its own drop rates which are rolled separately to the main drops.
