Achieve harmony by dealing damage with Light and Dark damage types in equal measure or by applying subclass buffs to your allies. Kinetic damage generates both Light and Dark energy.
While Transcendence is active, your grenade is replaced by a unique Prismatic grenade that deals both Light and Dark damage. Dealing melee damage while transcendent greatly increases your grenade energy regeneration, and vice versa. Defeating targets while transcendent extends its duration.
