Destiny 2 Warlock BuildNecrotic Scales

This build will provide you with massive ad-clear and a ton of super damage.

With spirit of the necrotic, you will be able to spread poison with your weapon and melee. Weapons that can take advantage of this are Thorn, Osteo Striga, Touch Of Malice, and Necrochasm. It's up to you what you choose, but Necro has been my go-to. Your melee will also apply unravel to an enemy and the poison will do damage over time to constantly spread the unravel.

With spirit of the star-eater picking up orbs of power while your super is full will overcharge it to do more damage. Nova bomb will be your best choice with this as it will get benefits from your fragments.

With facet of dominance, your void grenade will weaken targets, and with the facet of courage, your light abilities will do more damage to enemies affected by dark debuffs. This means you can throw your vortex grenade and an arcane needle to maximize nova bomb damage. You can also use your transcendence to throw your grenade, which can also weaken and apply slow, which is a darkness debuff.

Other things to help out with the build are things like devour so you can heal and get grenade energy on every kill. Facet of grace will let you get to your transcendence a lot faster. Finally, facet of hope will let your class ability recharge faster which is great because that means you can spam more hellions for more damage.
