"These pesky little creatures only have eyes for one thing: LOOT! They are faster than a Spring Trap, and their hunger for resources is limitless."
Level 1 & 2
Level 3 & 4
The Goblin's appearance is that of a small, green creature with large pointy ears, red eyes with green pupils and a red-tipped nose. Goblins wear brown pants and shoes. They also have a large sack, ostensibly for carrying resources stolen from your enemy.
The Goblin is the fastest ground unit in the game. Their first target is Resource Buildings, making them the ideal troop to deploy if your primary concern from a raid is collecting resources.
Because the nature of the character is to attack Resource Buildings first (ignoring all defenses) they can be vulnerable to attack and should not be deployed without another type of troop (such as the Giant or Barbarian) as a meat shield.
A Goblin's greatest weakness are splash-damaging structures (i.e. Wizard Towers, Mortars) as they group together. To combat this, send in Goblins in waves rather than spawning them all at once. Alternatively you could send in Giants and Barbarians and let them serve as distractions while the Goblins do the rest.
Another good strategy is to place a couple of goblins when the defenses are destroyed to help clean up any remaining buildings before time runs out.
Goblins are excellent at triggering Traps (especially Bombs), as their movement speed can allow them to get out of range before it detonates. This is especially helpful in the Single Player Campaign where there are often a large number of bombs in predictable places.
Although generally not viewed as the best defensive troop, Goblins are still useful as Clan Castle troops. As there are no resources to target, Goblins will attack the enemy very quickly compared to the other troops.
Goblins have the highest damage of any of the Tier 1Units and can engage the enemy units quickly due to their fast movement speed. They are particularly proficient at taking out small numbers of Giants on defense.
At level 6, goblins gain a red leather cape and a golden necklace.
The color of the Goblin's loot sack changes every other level (dark brown at level 1, striped dark and light brown at level 3, light brown at level 5 and 6).
Goblins are the main antagonist in the Single Player Campaign, despite the fact that you can train them as part of your army. Your own Goblins seem to have no compunction about attacking their NPC brethren.
When you tap on the Army Camp the Goblins stationed there all turn and look to their left for a brief moment.
