The Warlock is a class in Destiny which specialises in combining "space magic" powers granted by The Traveler with modern weapons. Warlocks have long studied The Traveler, which gives rise to their ability to harness some of its powers. [quote]"Warlocks have long studied the Traveler, mastering some of its arcane energies. Its true perpose still remains a great mystery, but discovering truth has always driven you into the unknown. Now, our enemies are the only thing that stands between you and the lost wonders of our Golden Age"[/quote] Warlocks use a combination of guns and space magic to defeat enemies and overcome the odds. I know I am again referencing Mass Effect 3 multiplayer here but perhaps it plays out like an Adept? Using a combination of special ammo types and it's space magic to throw enemies, slow them down or maybe even freeze them in place, which would allow you to do some serious damage when they cannot fight back. They gained their space magic powers by studying The Traveler. Warlocks can be distinguished by their rounded helmets and long coats. Also, as with the other player classes, in addition to head, chest, arm, and leg armour, a Warlocks fifth armour piece, unique to their class is a bond (armband) worn on the upper-left arm. Again, perhaps we will EB able to place an emblem on the armband to separate our Guardian form others?
