Merchants are characters that manage shops in some Castlevania games. They'll sell a number of useful items to the protagonist, which generally include: consumable items, weapons, armor, accessories, and even key items in some instances.
In some games, they will also buy any jewels the protagonist has found during their journey, with varying prices in accordance to their value. In most recent games, however, merchants will instead buy most items from the player's inventory (usually at 10% of their actual price).
In addition, merchants at one point will start selling a unique, powerful and the most expensive item in the game, which usually grants a major ability.
