Destiny 2 Hunter BuildCleaver of the Flain

• After getting 6 hits with the projectile or melee of the glaive, the glaive's special reload will be charged. Upon holding your reload input, you will gain +1 special ammo and your next projectile will turn into a healing turret on impact.
• The healing turret lasts in the environment for 15 seconds, and emits a healing projectiles towards allies not at 100% health within a 30 meter radius to the turret.
• Healing projectiles apply Cure x1 and Restoration x1 for 4 seconds.

• While 3 enemies are within 15 meters from you, your glaive will gain +50 reload and +100% extra melee damage. Lingers for 5 seconds once no longer surrounded.
• Upon getting a glaive melee kill, 1 ammo will be overflowed to the magazine, granting up to double magazine size. Upon getting a glaive projectile kill, enemies will emit an explosion matching the element of the glaive.

Regeneration is a frequently forgotten buff in Destiny 2 due to it being overshadowed by stronger healing effects, however, this build can make it uniquely effective.

Regeneration will regenerate the player's health until it reaches 100%, however it can be interrupted by taking direct damage. This build has two main sources of Regeneration, the Facet of Blessing Prismatic Fragment as well as the Better Already Armor Mod. The key to maximizing Regeneration's effectiveness is understanding the fine print about direct damage stopping the heal. As long as the damage source doesn't hit the player directly or affect the Health/Shield bar directly, the heal will be uninterrupted, so:

• Facet of Blessing will trigger on glaive melee kills, you can then Aim Down Sights with the glaive to put up the glaive shield and as long as the damage doesn't worm its way around the shield to hit your body directly, you can take all the hits to the shield in the world and your health will just keep on coming back until your shields are full.
• Better Already will begin health Regeneration on Orb pickup. This synergizes with Facet of Purpose in your subclass, since you're running a void super (Deadfall Tether) picking up an Orb will also grant you a Void Overshield. This Void Overshield will in essence act as a buffer between any received damage and your health bar, making every Orb pickup a full heal as long as you aren't hit by something so hard it completely peels off the Overshield and damages you directly.

This, combined with the Invisibility from Stylish Executioner as well as the Restoration from Edge of Intent's Healing Turret, means this build is a Swiss Army Knife of ways to get your health back and get you out of tough situations.

Just a couple more uniquely fun interactions this build highlights that I couldn't fit anywhere else:

• The Ascension Aspect now also triggers the effect of your equipped class ability, so with Acrobat's Dodge, you can grant yourself and nearby allies the Amplified (+15% damage Resist and less accurate enemies) and Radiant (20% increased weapon damage) buffs for activating Ascension. Ascension's AOE Jolting effect can also trigger Stylish Executioner, giving you Invisibility. That's a buff from all three light subclasses on one button press. That will then synergize with Facet of Hope, granting you +60% Class ability regeneration rate while you have 2+ elemental buffs, letting you spam Ascension pretty much whenever you need it.
• Stylish Executioner, on top of making you invisible after defeating an enemy with an elemetal debuff applied to them, will also make your next melee attack while invisible will apply Weaken. Surprisingly enough, this works with the glaive melee, letting you chain invisibility back to back as long as you wait for the "Too Stylish" cooldown to expire before going for your next melee hit.
• Not as wacky as the two previous, but Triton Vice's Exotic Perk and Facet of Protection have the same activation criteria of being within 15 meters of 3 or more enemies, granting you extra melee damage and damage resist together. This just makes the glaive melee feel good to use.
