Goblins

Goblins are a type of mobs that spawn in the Goblin Burrows in the Dwarven Mines. There are multiple types of Goblins that can spawn:

Drops
Goblin drops are affected by Magic find, Looting and Luck (Goblin Armor only)

Murderlover
Murderlovers attack by launching their enchanted fishing rods at players, dealing a large amount of damage. Murderlovers have a cooldown to how fast they can attack again of approximately 2 seconds. They have 50,000 health and wear red dyed leather chestplate and chainmail boots. Killing Murderlovers counts towards the Goblin Raid Slayer commission. Try to dodge their fishing rods and avoid corners where they can easily hit you and kill you. It is recommended to boost your defense as it is good for tanking their hits and killing them with your weapon.

Pitfighter
Pitfighters are equipped with chainmail armor and wield an iron axe. They have 30,000 HP, and move about as fast as a crouching player.

Knifethrower
Knifethrowers hold stone swords that they throw at the player, dealing a fair amount of damage.

Trivia

 * Goblins appear always looking straight down, to give the appearance of being shorter and hunched over.
