Archers are the most basic back-row units in the game. Compared to front-row units, back-row units face less pressure to survive.
Additionally, the shooter tag is quite powerful, capable of eliminating an enemy unit right at the start of battle. This is especially advantageous when facing certain single-target boss fights.
Sniper and Ranger are the two upgraded classes of the Archer line. The Sniper's attributes lean more toward attack, and she can directly strike enemy back-row units. The Ranger, on the other hand, focuses on improving survivability, as her evasion skills can work miracles in many situations.
Marks Girl and Cannonneer are the advanced upgraded classes of the Sniper. The Marksman is an extension of the Sniper in terms of skills and attributes, further emphasizing single-target offensive capabilities. The Cannoneer, meanwhile, can deal high AOE (area of effect) damage, but with the drawback of requiring a one-turn delay before activation. (The "Murderousness III" shown in the image represents a 30% critical rate.)
Windwalker and Bow Saint are the advanced upgraded classes of the Ranger. The Windwalker is a pure extension of the Ranger, as her "Windwalk" skill grants 100% evasion for its duration, making her nearly invincible. The Bow Saint's strength is slightly more complex: first, she has a wider variety of bonds; second, her base stats are higher; and she also possesses impressive burst skills.
