Flame Whip

Appearance in Rondo of Blood/Dracula X Chronicles, Castlevania: Dracula X
25 hearts and the lack of any sub-weapon will allow Richter to ignite his whip and strike anything in front of him in a blaze of holy flames.

Appearance in Order of Shadows
The flame whip is found hidden in a breakable block near the first section that Desmond can slide underneath. It is slightly more than double the strength of the Leather Whip that he starts the game with.

Symphony of the Night
This weapon can only be used when Richter Belmont has no sub-weapon. Using the Item Crush without a sub-weapon ignites the Vampire Killer with holy flames, giving his whip attacks fire damage as well as holy. Unlike its appearence in Rondo of Blood however, this is a timed power-up rather than a powerful one-attack Crush. It also costs 10 hearts less.
