The choice of rogues, thieves, or basically any agile unit that rely on lightning-fast attacks and critical backstabs while maintaining low aggro and visibility. This skill tree shares a link with the Scimitar skill tree that leads to the Scout EX skill. Most of the Dagger sword Skills increases the backstab damage and critical rate while some add very useful debuffs like attack down and defense down. Unfortunately, you cannot dual-wield daggers in the game so you have no choice but to have a shield partnered with it for additional stat boost and protection.
