Castlevania: Harmony of Dissonance Items
Potion
This is the standard healing item found in many role-playing games. In this game, it heals 70 hit points. It can be bought at any one of the Merchant's booths for 80 gold pieces. It is also dropped by many different kinds of monsters.
High Potion
This item is also found in many role-playing games. It functions the same way as it usually does, meaning that is a more potent curative item than the typical potion. The Merchant sells these items for 200 gold pieces each. Its urn is larger and more highly wrought than the potion's.
Elixir
This is the ultimate potion. As it says in the description, this will restore all lost hit points. They can be bought for 800, or found lying somewhere in the castle. There aren't any monsters that drop this item.
Mana Prism
This little pill is the standard magic replenishing item. Even though it is such, it's pretty rare. It can only be bought at the Merchant's booths in the Entrance and Clock Tower for the high price of 250 gold, and the only monster that drops this is the Siren. It can be found resting in a few positions in the castle, however. It restores 20 magic points.
Big Mana Prism
This is a pharmaceutical bottle that contains many Mana Prisms. As such, it replenishes more magic points than the ordinary Mana Prism. To be exact, it restores 100 magic points. It can either be purchased at the Merchant's booth at the Entrance for 1,000 gold, or taken from defeated Sylphs and Pixies at Luminous Cavern.
Drumstick
This leg of fowl is another one of the meat foodstuffs that is usually found in Castlevania. It restores 100 hit points. It cannot be bought, so you must either find it somewhere, or fight 0 for it.
Turkey
Like the drumstick, this poultry isn't sold at all. This item restores 200 hit points.
Anti-Venom
First of all, kudos to KCET for not predictably dubbing this item ‘Antidote'. As is said in the description, this medicine negates the negative poison status. It can be procured from the Merchant for a paltry sum of 20 gold pieces.
Uncurse Potion
This lilac hued tonic cancels out the bothersome curse status effect. Just like the Anti-Venom, the Merchant sells these for the small amount of 20 gold pieces.
Medicine Jar
The Invisibility Potion makes its triumphant return! Its effects are exactly how you remember them from older Castlevania games. The concoction within the golden lamp will turn Juste opaque, and will make him impervious to enemy attacks for a short time. This is another infrequent item. It can either be bought at the Merchant's Entrance based stall for a whopping 10,000 gold, or picked up at a few select spots in the castle.
Lure Key
This key allows Juste to open the many sealed lustrous doors in Count Dracula's Castle, thereby giving him full access to the inter-dimensional gateways, which also serve as warp points. It is hidden away in Castle B's Entrance.
Skull Key
Once Juste retrieves this key from the chiseled tunnels of Luminous Cavern, he will be able to open the skull pattern doors, which are depicted in the game select screen.
Floodgate Key
This key fits into a drainage mechanism that siphons the water out of flooded areas of Luminous Cavern. It is found in Skeleton Cave.
