Castlevania: Portrait of Ruin/Dual Crush Skills

From StrategyWiki, the video game walkthrough and strategy guide wiki

Dual Crush skills are a sort of 'overdrive' move used within Portrait of Ruin. These are often very useful if there are multiple enemies and you wish to deal a large amount of damage to them, if not kill them outright. Surprisingly, some of the 'weaker' Dual Crush skills remain useful even in the later stages of the game.
