Tactics and info
They are critical in the early game, together with the Griffins, due to them being almost the only Castle ranged attackers, having good damage and also the marksmen's twice shot. However, with each ranged attack in a turn, the Marksmen will use up two shots, not one. Still, getting them damaged should be avoided, due to their hp and defense stats being equal and respectively lower than the level 1 Pikeman and Halberdier.
