Goblin Barrel

"Spawns three Goblins anywhere on the Arena. It's going to be a thrilling ride, boys!"

Summary

The Goblin Barrel is unlocked from the Goblin Stadium (Arena 1).
It is a Spell that launches a barrel from the player's King's Tower.
Upon impact, the barrel ruptures open, dealing minor damage and unleashing three Goblins.

Strategy

If there is a Tombstone or Goblin Hut protected behind an Arena Tower, the player can use the Goblin Barrel to take them out quickly.
- For high effectiveness, deploy a high hitpoint troop like the Knight or Giant on the chosen side. When the Tower has targeted the player's high hitpoint unit, deploy the Goblin Barrel, and they will go to work unhindered.
- The above strategy also works vice versa. If you have a troop that deals high damage but has low or even moderate health, deploy the Goblin Barrel first and then drop the troop. This strategy is effective with Hog Riders or even Mini P.E.K.K.A.s. The Goblin Barrel will draw enemy fire while the other troop easily destroys the opposing Crown Tower.
The Goblins from the Goblin Barrel have high DPS, but relatively low hitpoints. If placed accordingly with high hitpoint units that will distract the Crown Tower and any defending units, the Goblin Barrel can deal extremely high damage in a relatively short amount of time.
- As Goblins have relatively low hitpoints, they can quickly be eliminated by Crown Towers. When using a Goblin Barrel to attack a King's Tower, either distract or destroy the Towers to prevent your Goblins from being destroyed.
Arrows and (almost) every other Spell can be effectively used to directly counter Goblin Barrels.
- Be sure to launch the Spell before the Goblin Barrel's impact due to the cast time of Spells.
- This is not the case with the Poison.
- The Zap is the best and cheapest counter to the Goblin Barrel.
  - Do not launch the counter Spell too early, as early Spells have no effect on the Goblins.
- However, adept players can cast the Goblin Barrel in the far corner of the opposing territory, out of the radius of the defending player's Arrows instinctively cast "on" the Crown Tower. This allows the Goblins to survive.
If you have no Spells readily available, you can use cheap distracting troops and/or area damaging troops such as Bombers, Goblins or Skeletons to prevent the spawned Goblins from dealing severe damage to their intended target.
As the description says, the Goblin Barrel can be fired anywhere, allowing players to finish off buildings they cannot reach.
The Goblin Barrel can be used to force the opponent to use their Arrows, Zap, or other Area Damage Spells, allowing the player to swarm their opponent with cards such as the Skeleton Army and Minion Horde.
You can use Mirror to do extra damage on Crown Towers.
