"Warrior-scholars of the Light, Warlocks devote themselves to understanding the Traveler and its power. A Warlock's mind is an arsenal of deadly secrets, balanced between godhood and madness. On the battlefield, those secrets can shatter reality itself."—Grimoire Card: Warlock
Warlocks boast the highest recovery of Destiny's class triad, sacrificing resilience and agility for the ability to regenerate health with tremendous alacrity.
Much like its Titan and Hunter brethren, the Warlock class is divided into three subclasses at present; each specialization offers unique abilities and alters the manner in which the class is played. Shared among the subclasses is the Rift class ability; this technique is further divided into Healing Rift and Empowering Rift, each allowing players to buff allies with increased health regeneration and damage output.
In New Light all of the subclasses are unlocked from the beginning.
- Dawnblade was automatically unlocked during the campaign mission Spark.
- Voidwalker was unlocked at level 8+ by obtaining the Warped Armlet Class Relic and charging it by completing various activities.
- Stormcaller was unlocked at level 15+ by obtaining the Cracked Talisman Class Relic and charging it by completing various activities.
- Warlock is the only class which had its melee attack altered due to the loss of Light in the Red War campaign. From the beginning of Adieu to near the end of Spark missions, Warlocks used the Punch instead of the Palm.
- Since player characters no longer lose their abilities during that story in New Light, Warlocks now keep their Palm attack in those missions.
- In the Destiny 2 Beta the Warlock melee range was greater than that of a Titan or a Hunter, with slower melee speed to compensate. When the game launched, however, the range had been nerfed to be the same as the other classes; but the speed was never brought up to other class melee speed.
- The Palm's range was increased in Season of the Worthy.
