Gold Golems are a solid ground unit, stronger but similar to the Iron Golems of the Tower. They have great magical resistance, with damage from spells being reduced by 85%. With this, spells are unlikely to be effective, and thus attacking with ranged units is a player's best option. They are only surpassed in terms of other Golems in the game by the Diamond Golem.
