The Buckler is a Tank Type unit unlocked at Player Level 2.
Description: “Reduce damage from attacks with the shield and counterattack with the sword. The shield can reduce the damage, and defend against poison attacks.”
The Buckler is the first Tank that you unlock in Craft Warriors. This unit is fairly useful at the beginning of the game, but its mediocre amount of hp and damage (it’s also slow), so it’s better to replace it with better tanks, like Paladin or Titan, although the cost is much cheaper than other tanks and it's easier to upgrade.
Buckler’s shield can reduce 50% of taken damage and prevent poison attack. However, it still gets damage from combustion, so when you reach the point where enemy castles have Fire Archers and Mortars, it will die pretty quick even for a tank. Also, just like the Paladin, its shield can be blasted away by wind cannons, Blast Gunners and Samurai’s Lai move.
The Buckler also has a minor skill: when an enemy attacks it, after parrying the attack with the shield, this unit counter-attacks with the sword, representing a great threat for units like the Lancer.
