“It rolls over and damages anything in its path, then breaks open and out pops a Barbarian! How did he get inside?!”
The Barbarian Barrel card is unlocked from the Barbarian Bowl (Arena 3). It is an area damage spell with a moderate area of effect and damage. When cast, the Barbarian Barrel rolls across the Arena, damaging ground troops and buildings in its path. After rolling for 5 tiles, it will break open and release a Barbarian. A Barbarian Barrel card costs 2 Elixir to cast.
The Barbarian Barrel can be used in a similar manner to The Log, but it will not reach the Princess Tower before releasing its Barbarian. However, the Barbarian can follow up and attack anything still alive.
The Barbarian Barrel excels at countering support troops such as Wizard, Witch, and Executioner. If the Barbarian spawns near the troop, the barrel's damage and the Barbarian's damage can kill the troop.
The Barbarian can be used as a tank for a mini-push.
Therefore, it synergizes well in Graveyard decks as not only a defensive support card, but also a secondary tank that threatens the tower on its own and tanks for the Graveyard's Skeletons.
If cast at the bridge, the Barbarian from the barrel will attack the tower twice, dealing decent chip damage if ignored.
The Barbarian Barrel cannot take out equal level Princesses, Dart Goblins, or Rascal Girls with just the barrel's damage, meaning an extra swing from the Barbarian is needed. However, a Barbarian Barrel one level higher than these units will be able to take them out without the Barbarian's help.
