Her body is covered in an exceptionally strong golden shell, making it difficult to attack without the Hunter's weapon bouncing off. She is slightly larger than the average Rathian.
The Gold Rathian is weakest to the Thunder Element and is, like all Rathians, capable of inflicting the Poison ailment and shooting Fireballs. She is able to wield her flame sac with greater control and ferocity than the common species.
Gold Rathian must be very aggressive to survive, accounting for their heightened aggression compared to the standard and pink subspecies.
Gold Rathian have been most commonly spotted at Ancient Tower, Misty Peaks and less commonly the Swamps. However, it is safe to assume that the Gold Rathian could survive in the same environments as the green and pink species, being much tougher.
