Shop

Shops appear in various Castlevania games, and primarily serve as the main hubs for buying and selling items, and weapons. In most cases, a non-playable character opens their business to aid the playable character.

The items in a shop are bought with a common currency - Gold which can be accumulated in various ways. Throughout the games, these shopkeepers often have limited stocks, and new items and weapons become available as the player progresses more into the game. Likewise, the rarest or strongest items, accessories, and weapons become available in the shop with expensive costs after the player beats the game and re-visits the shopkeeper.

Castlevania: Symphony of the Night
The Master Librarian provides Alucard with several one-use items, and pieces of equipment upon visiting him in an area of the Long Corridor. Visiting the Reverse Castle and attaining a high Rate unlocks new items in the shop. The Duplicator is the most expensive item sold, which can be unlocked after defeating Dracula.

Castlevania: Curse of Darkness
Julia Laforeze sets up a shop for Hector in this game. Several consumables, and basic weaponry are being sold in her shop. Not only that, she can also house the Innocent Devils which are not required by the player at the moment. She can also create new Innocent Devils from the Devil Shards dropped by these creatures.

Castlevania: Aria of Sorrow
Hammer opens his shop in the Castle Entrance only after meeting Soma Cruz for the first time. The items, and weapons that he offer increase depending on the map completion rate.

Castlevania: Dawn of Sorrow
Hammer once again serves as the shopkeeper in Soma's second game. And similar to the first, the items, and weapons being sold increase on map coverage. But these time, he also sells "UMA Newspapers" which only provide gameplay hints. New weapons forged through Yoko's Weapon Synthesis become available from the shop once discovered. Interestingly, Hammer and Soma Cruz have several dialogues each time the player interacts with him after defeating bosses or increasing the map coverage.

Castlevania: Order of Ecclesia
The shop system becomes available after Shanoa rescues the second villager, Jacob. He only sells a very few number of items from the start. But new items are added each time Shanoa defeats a specific boss, or completes a quest from the other Wygol Villagers.
