Winter's Soul Siphon Warlock Build – Solo Ultimate

Monument of Triumph, Destiny 2's final live-service update (June 9, 2026), shipped a new Void Warlock aspect called Soul Siphon. It attaches to Pocket Singularity. Land a powered melee hit, press melee again, and a tether drains up to four nearby enemies simultaneously: dealing damage, granting Void Overshield, and refunding class ability energy. It is, objectively, a free heal that also murders things. Bungie released this to the public.

Hey! you! Yes! You! Guardian! I have a CRINGEBLOG promocode for our shop. Works Everywhere ;-)

The Destiny 2 Void Warlock build has become the fastest melee uptime setup in the game. Not "competitive." First. You punch something, you get your punch back, you heal, you get your grenade back, you throw your grenade, you get your punch back again. This is the Destiny 2 infinite ability loop. It has no natural exit point unless you miss or walk into a wall.

Hard counter: range. Soul Siphon tether is short. Aerial or long-range enemies will watch you drain nothing while your Overshield silently expires. Close the gap or swap to a grenade variant. That is the entire weakness section.

The Loop

Understanding Devour build mechanics is not optional. Devour activates on any void ability kill and extends on every subsequent kill. It is the engine. Feed the Void is the aspect that enables it. Everything else is plumbing.

Pocket Singularity (Melee 1)→Soul Siphon activates (Melee 2 prompt)Soul Siphon (Melee 2)→  Void Overshield + Devour + class ability energy  Devour proc (Feed the Void)→Full HP on kill + grenade energy returnedGrenade use (Echo of Provision)→Melee energy returned. Loop resumes.

Echo of Provision is the unsung piece: dealing grenade damage: even without killing: partially recharges your melee. Combined with Devour handing you grenade energy on kills, you will deplete enemy waves before you deplete your abilities. Embarrassing for the enemies.

Aspects & Fragments

Aspects (both required)

Echo of Provision is the backbone of the Voidwalker melee uptime loop. The other three are stat padding and ad-clear bonuses. Swap Expulsion and Instability freely to preference; swap Provision and you've built something worse.

You probably vaulted these. Winter's Guile exotic gauntlets have been in the game since Season 1 and were last considered relevant approximately never. The perk is Warlord's Sigil: melee and finisher kills stack it up to 10 times, each increasing melee damage. At 10 stacks, Warlord's Fury activates.

Warlord's Fury at max stacks grants 400% additional base melee damage and regenerates melee at 38.4x normal speed. You punch something, you immediately have melee again. Finishers grant 3 stacks instantly: useful for entering encounters hot.

Decay warning: Stacks decay one at a time every 4.75 seconds. Warlord's Fury lasts 10 seconds, then resets everything. Stop punching and you are nobody. Cope.

The alternative is Nezarec's Sin: its ability regen loop feeds directly off Void ability kills from Soul Siphon. Use it if you need the flexibility. But Winter's Guile with Soul Siphon turns the build into a Destiny 2 champion killer at 10 stacks. Choose accordingly.

Stat Priority

This is not a balanced spreadsheet. The build needs one thing: melee up as fast as possible, forever. Three stats matter. The rest is furniture.

• 180
• Melee: Primary
• 100
• Super
• 100
• Recovery

Strength investment directly increases Soul Siphon's drain damage and energy return. Armor 3.0 set bonuses from Monument of Triumph make reaching 180 Melee achievable without sacrificing Recovery. If you can't hit 180, prioritize Melee over everything. Grenade stat is irrelevant: Feed the Void and Echo of Provision keep it full.

The weapons exist to not embarrass you at range. Soul Siphon handles everything within tether distance. Outside it, you need something that closes the gap or applies pressure at range.

Solo Ultimate: Heist Battleground Moon

The Solo Ultimate Heist Battleground Moon clear this build demonstrated is not a cheese. It is the build working as intended at peak melee stack count. Here is the approach, condensed to what actually matters.

Phase 1: Entry Wave

• Open with a grenade to trigger Echo of Provision and prime Devour via the first kill.
• Stack Warlord's Sigil to 3–5 before the first champion. Use finishers on red bars to jump to 3 stacks instantly.
• Never let stacks drop. If there's a lull, find a red bar and punch it. It doesn't have to be a good idea, just a fast one.

Phase 2: Champions

• Reach 10 Warlord's Sigil stacks before engaging. At 10, a single melee sequence can one-shot champions outright.
• Overload Champions: Pocket Singularity's tracking handles the first hit. Tether handles the drain. Finish with a finisher for 3 free stacks into the next encounter.
• Barrier Champions: open with a Volatile Rounds burst from Echo of Instability, then close.

Phase 3: Boss

• Heavy weapon for burst damage windows.
• Maintain Devour throughout. If Devour drops, immediately throw a grenade and re-engage adds before returning to boss.
• Overshield from Soul Siphon doubles as damage mitigation. Stay in tether range of adds during boss phases to keep it refreshed.

Failure condition: Geometry. Pocket Singularity occasionally disagrees with your target on terrain. This is the build's only real vulnerability. If a wall eats your melee, throw a grenade, buy time, reset. That is the entire recovery guide.
