Overwhelming power from two blades
The appeal of the Dual Blades is the strong attack power that comes from a blade in each hand. Their high mobility and many hits are like the Sword and Shield, but with a second blade in place of the shield they lean even further into attacking. Their main feature is Demon Mode. While it is active your Stamina keeps draining, but your Attack and movement speed go up, you get super armor, and you can use the Demon Dance, an 11-hit combo. Attacks in the Demon Dance never bounce off, so it works especially well on monsters with hard hides. Hit a weak element with a high-element weapon and the Demon Dance does big damage in a short time. The price for all that attack power is that they cannot guard, and once the Demon Dance starts it cannot be stopped. On Low Rank quests you can get by on strength, but if you take on High Rank quests or harder, you need to learn to dodge.
