Utility Skills


This celestial booster build is great offensive support made for open-world and is beginner friendly. The equipment above is designed to be played with no modifications from the exotic gear obtained by the level 80 booster. If one does not have the level 80 booster available to them then the equipment can be obtained through crafting or purchasing directly from the trading post. This build utilizes the elite specialization of harbinger. Specifically, this build will allow you to provide permanent QuicknessFury, and 25 Might. In addition to bringing boons, this build also has a large amount of crowd control and boon corruption.

Build Fundamentals

This build is able to maintain permanent Quickness, Fury,and 70% Regeneration on allies while maintaining 25 Might. It offers some Protection by using Spectral Armor, and also gains Stability and Swiftness when entering Harbinger Shroud.

Unique to Harbinger is the Blight mechanic Blight. Blight reduces your maximum health while providing you with offensive bonuses. You will be using Elixir of Promise and Elixir of Anguish to maintain some stacks of Blight. To help mitigate the effects of Blight, you will be using a pistol and staff at range. It’s important to know that you give people boons around you while in a shroud, so staying at range is only good while playing alone.

Your main weapons are going to be a pistol/warhorn. Using Weeping Shots and Vile Blast to deal damage, and using Wail of Doom for crowd control. When pressured by condition damage you will want to use Putrid Mark to cleanse yourself and Mark of Blood to gain Regeneration. Since you will be running soul marks, your staff skills will be unable to be blocked. We can use to cancel blocking skills by using Reaper's Mark.

Since you gain all your offensive boons while in shroud you want to enter it off-cooldown. Use shroud Tainted Bolts and Dark Barrage until shroud runs out (Tainted Bolts is how you gain Might via Reaper's Might). Use Voracious Arc and Vital Draw for additional crowd control, and Devouring Cut when the enemies are already crowd-controlled.

You are also going to be using Summon Flesh Golem. Use this for crowd control and as a tank.

Crowd Control


You can replace Spectral Armor with Well of Suffering for additional damage. Additionally, exchanging Summon Flesh Golem with Elixir of Ambition will allow you to gain every boon in the game.
