Roc

Roc is basically the Desert version of the Ice Golem. He has a 3% chance of spawning upon entering a Desert Biome in Hard Mode. During the fight he flies around a like a Vulture and periodically swoops down at the player. He is able to travel through blocks so when he swoops down, he'll fly underground momentarily before coming back up. The other way he attacks is by charging across the screen much like the Queen Bee while breathing sand particles like Spazmatism's cursed flames. He has 3,000, 3 melee damage, 42 ranged damage and 50 defense.
