Permafrost — Mask of Fealty + Conditional Finality (Stasis Hunter)
Anchor: Mask of Fealty (Helmet) · Subclass: Revenant (Stasis) · Role: Withering-Blade shatter engine + a guaranteed-freeze shotgun — every Conditional Finality freeze is a blade-spread trigger, with built-in Unstoppable Sandbox: 9.7.0 · Created 2026-06-24
Mask of Fealty turns a frozen target into a button: shatter it with a Withering Blade and you get a whole fan of blades back. The problem is manufacturing freezes on demand. Conditional Finality solves it — its Stasis barrel freezes on hit (and it stuns Unstoppable intrinsically). So you freeze with the shotgun, shatter with a blade, get a spread, plant crystals, build Frost Armor, and do it again. The shotgun is the trigger the Withering-Blade loop was missing.
The pairing — why two exotics, not one
Mask of Fealty is the 
helmet, Conditional Finality the Special — both Stasis:
Mask of Fealty makes Withering Blade self-funding (every hit/bounce → a crystal + melee refund) and turns shattering crystals or frozen targets into a spread of blades. Its weakness is the field drying up — no freeze/crystal nearby, no spread.
Conditional Finality is an on-demand freeze: the Stasis barrel freezes what it hits, plus intrinsic Unstoppable. A guaranteed shatter-trigger in your back pocket whenever the crystal field runs dry — far cleaner than the generic "Chill Clip special" the Frostblade build had to approximate.- They meet on Freeze: Conditional freezes → Mask of Fealty shatters the frozen body with a blade → spread → crystals + Frost Armor → repeat. The Solar barrel adds a second damage type for shielded targets too.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Super |  Silence and Squall | Freeze kama + roaming shatter-storm; every freeze it lands is another Mask of Fealty shatter-trigger. (+63% vs combatants since Renegades.) |
| Class ability |  Gambler's Dodge | Melee refund (scaled by Melee, doubled near enemies) + Winter's Shroud slow on dodge. |
| Melee |  Withering Blade | Mandatory — the bouncing Stasis shuriken the exotic is built around. |
| Grenade | Glacier | A guaranteed crystal cluster to shatter for the spread; Touch of Winter spawns extras. |
| Aspect 1 |  Grim Harvest | Stasis-shard pickups → Frost Armor (DR); with Frost Armor your Stasis/Kinetic kills can chain-shatter — free survivability + AoE under the blade loop. |
| Aspect 2 |  Touch of Winter | Enhances Stasis grenades (Glacier → extra crystals) — more shatter fuel. (Shatterdive is the aggressive alt.) |
Whisper of Rime Frost Armor duration + cap — the DR backbone
Whisper of Fissures bigger shatter burst → bigger blade-spread triggers
Whisper of Shards crystal shatter → grenade regen, refilling your crystal-maker
Whisper of Conduction nearby Stasis shards track to you — funnels Grim Harvest shards into Frost Armor
Whisper of Fractures shattering a frozen target with melee → a Frost Armor stack — your blade shatters are melee
Exotic armour — Mask of Fealty (Helmet)
Null Factor: Withering Blade hits and bounces create a small Stasis crystal and refund a portion of melee energy. Using Withering Blade to shatter crystals or frozen targets releases a spread of Withering Blades.
Two clauses, one engine: clause one makes Withering Blade self-funding and litters the floor with crystals; clause two turns those crystals and any frozen target into a blade spread. Throw → crystal + refund → throw into a crystal/frozen body → shatter → fan of blades → each makes crystals + refunds. It compounds.
Exotic weapon — Conditional Finality (Shotgun · Stasis/Solar · Special)
Split Decision: "Dual barrels split into Stasis and Solar damage. Strong against [Stagger] Unstoppable Champions."
A 55-RPM Special shotgun firing both elements at once. The Stasis barrel freezes the target (the shatter-trigger this build runs on), the Solar barrel adds ignition potential and chews shielded enemies, and the weapon stuns Unstoppable intrinsically — a champion Frostblade had to bring a separate frame for.
Why this works (the mechanics)
- Conditional manufactures the shatter-trigger on demand. Mask of Fealty's payoff needs a crystal or frozen target; the Stasis barrel freezes whatever you shoot, so a blade into that frozen body is an instant blade spread even when the crystal field is empty. The two exotics hand off cleanly: shotgun freezes, blade shatters.
- The melee economy is a closed loop. Mask of Fealty refunds melee on every hit/bounce (feed 1), Gambler's Dodge refunds it (feed 2, doubled near enemies), Heavy Handed returns it on melee kills (feed 3). Three feeds, one cheap ability → Withering Blade is effectively always up.
- Crystals are stored AoE you detonate with the same button. A blade shatters the crystal and gives you a spread; Whisper of Fissures makes the burst bigger, re-seeding the field as it clears.
- Frost Armor is free survivability the loop builds itself. Whisper of Fractures grants a stack per blade-shatter of a frozen target; Whisper of Rime extends duration + raises the cap (50% DR at 7). You shatter constantly, so DR refreshes faster than it decays.
- Champions fall out of the chain. Conditional and Stasis shatter both stun Unstoppable (9.7.0 reverted shatter→Unstoppable); slow/freeze covers Overload behaviour. Cover Barrier with a Precision/Adaptive frame.
Weapons
- Conditional Finality (Special) — the freeze button + Unstoppable.
- Stasis primary with Headstone — precision kills plant more crystals, feeding the shatter-spread loop without spending a blade.
- Champions (Anti-Champion 2.0): Unstoppable — Conditional + Stasis shatter; Overload — slow/freeze (you produce it non-stop); Barrier — a Precision/Adaptive frame on the primary.
Stats & archetypes
Priority: Melee 150+ → Health 100 → Class 60 → rest dump.
- Melee is the keystone — uptime and the Gambler's refund both scale off it.
- Health rides the permanent Frost Armor; Class feeds the dodge that refunds melee.

Artifact — Slayer Baron Apothecary Satchel (Episode: Revenant)
Picks (2/3/2): 
Wind Chill + 
Crystalline Converter — 
Hail The Storm + 
Frost Renewal + 
Curative Orbs — 
Served Cold + 
Brain Freeze The Stasis artifact for a Stasis build — it pumps the exact verbs this loop lives on (Stasis hits, shatter, shards, Frost Armor):
- Wind Chill — rapid Stasis hits → Frost Armor, and hits on slowed/frozen → a Stasis Shard. Feeds DR and the shard pool in one (Conditional's Stasis barrel triggers it).
- Crystalline Converter — class-ability → next Stasis-weapon kill makes a Shard — more Grim Harvest fuel off the dodge you cast anyway.
- Hail The Storm — shattering frozen targets/crystals deals bonus damage + releases shards. You shatter every throw, so this scales the whole engine.
- Frost Renewal — with Frost Armor, critical damage freezes nearby + grants Frost Armor — free freezes to detonate + DR top-up.
- Curative Orbs — shield breaks → Orbs (the Solar barrel pops shields) → Armor Charge.
- Served Cold — Stasis-shard pickup → class-ability energy → recharges Gambler's.
- Brain Freeze — frozen combatants slow nearby ones → wider freeze field + Overload.

The loop
- Shoot a target with Conditional Finality → Stasis barrel freezes it (Solar barrel chips shields/ignites).
- Throw a Withering Blade into the frozen body → shatter → spread of blades → each plants crystals + refunds melee; Fissures makes the burst hit harder.
- Frozen/slowed kills drop shards → Conduction pulls them in → Grim Harvest → Frost Armor; blade-shatters grant more (Fractures + Rime).
- Glacier for a guaranteed cluster; Silence and Squall to freeze the room — every freeze is one more shatter-trigger for the next blade.
