The Blunderbuss is a 16th Century flintlock pistol-like shotgun that is unlocked at level 9. It contains 2 bullets, each dealing high damage and hitting with fairly decent accuracy. It costs 85 gold. The  Blunderbuss'  range is poor, but is very light, resulting in a very high agility stat.

Strategy
This weapon is best used for taking out close range targets. Its damage slowly decreases the farther you are from the opponent. Its quick firing speed will aid you tremendously in battle, able to keep those bullet firing and enemies falling. The two closely-timed shots will kill ANYONE, provided close enough, and even if not fatal will reduce his health to a bare minimum so that the opponent will fall with the next shot. Use this weapon to your advantage by quickly destroying them before they get you.

Despite requiring close range and allowing enemies to catch sight of you and open fire, it is regarded as the most valuable premium weapon due to its outstanding efficiency and improvements from it's counterpart, the Shotgun.The price tag may seem a bit costly, but is considered one of the best weapons you can ever own in the game.

The  Blunderbuss'  greatest rival is the Double Barrel Shotgun, but due to its lower rate of fire, the Blunderbuss can easily dominate it in close quarters combat.
