If you need a specific pet to be an attacker in challenging the 3 main camps like a Goblin camp, I would recommend you the Fire Elemental. Its spinning fire fist can deal a lot of restraining fire damage to multiple goblins.
Name: Fire Elemental
Species: Element Creatures
Star Rating: ★★☆
Domestication: Tameable
Feature: Fire Invulnerability, Lava Skin, Fire Attack
Recommended weapons: Imprisonment Staff +4
Elemental creatures evolved from the fire element, living in volcanic areas for a long time. Their bodies are composed of volcanic magma and lava, which continuously emit heat energy to the surroundings. Even in the snow mountains, as long as you carry the fire elemental, you can be immune to the cold. In addition, it can also be used to make barbecue.
