From Destinypedia, the Destiny wiki
The caster conjures a sun-like sphere of energy that permeates the body, wrapping them in a bright glow. In this state, weapons become more powerful, and melee and grenade abilities recharge faster, allowing them to be used in rapid succession. Upgrades allow users to buff any allies nearby, and if cast after death even from the depths of nothingness, can restore the caster to life without the help of a Ghost or in a Darkness Zone, able to slip from the bonds of the material, able to shrug off physical harm, they may even elevate other Guardians with power too. The Warlock's weapons become more powerful when the ability is used. It even has a blinding affect on others.
