Centerpiece: Cryosthesia 77K (Sidearm · Primary · Stasis) · Subclass: Revenant (Stasis Hunter) · Role: Self-freezing primary sidearm that shatters its own targets for burst damage and mag feedback Sandbox: 9.7.0 · Updated 2026-07-03

A primary sidearm that makes its own crowd control. Land a kill, swap to LN2 mode, and the next charged shot freezes the target — then you shatter it with the same gun for a damage burst, and the catalyst refills the mag off the shatter. The whole loop lives inside one weapon. Mask of Bakris stacks a Stasis damage buff on top and refunds your class ability on the freeze-kill, so the shift, the freeze, and the shatter all pay each other back.

The weapon

Intrinsic — LN2 Burst: [Alternate Weapon Action] : Swap firing mode after a final blow to enable a charged shot.

Catalyst — Cold Efficiency: Shattering a frozen target refills this weapon's magazine from reserves.

Cryosthesia 77K is a 260 RPM Stasis primary sidearm. Land a final blow, then press [Alternate Weapon Action] to enter LN2 mode — the next shot becomes a charged Stasis burst that freezes the target it lands on (and clips nearby foes). That charged shot spends a chunk of the mag. You then shatter the frozen target — with this same gun's rounds, a melee, or any Stasis source — and the catalyst refunds the spent mag straight from reserves. The cost of freezing is repaid the instant you cash the freeze in. Because it is a primary, ammo is effectively unlimited; the only gate is "do I have a kill to arm LN2," which a Stasis add-clear subclass supplies constantly. It is a control primary that clears rooms, not a single-target DPS tool.

Loadout

Slot	Pick	Why
Subclass	Revenant (Stasis Hunter)	Freeze/shatter is the whole identity; supplies the kills that arm LN2 and the shatter sources the catalyst wants.
Super	Silence and Squall	Two Stasis kamas — Silence freezes a pack, Squall is a roaming storm; free freezes to shatter, and it keeps the Bakris/Hedrons buffs live.
Class ability	Gambler's Dodge	Bakris converts Dodge into the cloaking Shift that arms the Stasis weapon buff; Gambler's near enemies also refunds melee.
Movement	Triple Jump	Air control to line up the next LN2 charged shot or a Shatterdive.
Melee	Withering Blade	Stasis shuriken — slows, and shatters frozen targets to trigger the catalyst when you don't want to spend a charged shot.
Grenade	Duskfield Grenade	With Touch of Winter it seeds a crystal and a wider slow field — easy freeze fuel plus a crystal to shatter for shard/grenade regen.
Aspect 1	Touch of Winter	Enhances Duskfield/Glacier/Coldsnap — the Duskfield seeds a Stasis crystal on cast, manufacturing freezes and shatter targets for free.
Aspect 2	Grim Harvest	Frozen/slowed kills drop Stasis shards; picking them up grants Frost Armor (DR) and feeds Whisper of Bonds/Conduction.
Fragments	Whisper of Rending, Whisper of Fissures, Whisper of Bonds, Whisper of Hedrons, Whisper of Conduction	Rending is the single most important line for a primary shatter gun — see below.
Exotic armour	Mask of Bakris (Helmet)	Stacking Stasis weapon-damage buff after the Shift; weapon kills with the buff active refund class-ability energy → the Dodge that re-arms the buff.
Weapons	No Time to Explain (Kinetic Pulse) + Conditional Finality (Stasis/Solar Shotgun)	NTTE returns rounds vs Stasis-slowed/frozen targets (Cryosthesia freezes, it never reloads); Conditional Finality freezes on hit AND stuns Unstoppable — the build's champion answer.

Fragments

Whisper of Rending primary-ammo weapons do increased damage to Stasis crystals and frozen targets — the keystone for a primary shatter gun) · Whisper of Fissures (bigger, harder-hitting shatter burst — turns each freeze-kill into AoE) · Whisper of Bonds (frozen kills generate Orbs of Power, feeding the Super/mod economy) · Whisper of Hedrons (freezing a target grants weapon handling + health — keeps Cryosthesia snappy and tops you up on every charged shot) · Whisper of Conduction (pulls nearby Stasis shards to you so Grim Harvest's Frost Armor and Bonds' orbs actually reach your hands

Why it works (the mechanics)

The freeze → shatter → reload loop is self-contained. Kill arms LN2 → the charged shot freezes → you shatter the frozen target → Cold Efficiency refunds the mag from reserves. You spend mag to freeze and get it straight back by cashing the freeze in, so the gun funds its own crowd control with no external ammo economy.
Mask of Bakris is the Stasis-weapon multiplier and the class-ability engine. Light Shift needs a Stasis or Arc Super equipped — Silence and Squall qualifies. After the Shift, Stasis weapons gain a stacking damage bonus (10% / 21% / 33% at 1/2/3 stacks, per Clarity), and while Light Shift is active weapon kills refund class-ability energy. Cryosthesia is Stasis, so the Shift buffs it directly and your freeze-kills refund the Dodge → re-arm the Shift → keep the buff rolling.
Whisper of Rending double-dips the shatter. Rending buffs primary-ammo weapon damage against frozen targets and Stasis crystals. Cryosthesia is a primary sidearm, so both the shatter trigger and any clean-up rounds into the frozen body land at increased damage; stack it with Fissures' bigger burst and one charged shot deletes a cluster.
Touch of Winter manufactures shatter targets on demand. The enhanced Duskfield seeds a Stasis crystal on cast, and Rending nukes crystals too — so even with no kill queued you can throw a Duskfield, shoot the crystal for a Rending-buffed shatter, and proc shard/orb generation without needing a combatant.
Frost Armor is free DR layered under the offence. Grim Harvest converts the shards your freeze-kills drop into Frost Armor; Whisper of Hedrons tops health on every freeze; Whisper of Conduction drags loose shards into pickup range. You tank while you freeze-lock the room.
Champion coverage is bought, not intrinsic. Cryosthesia has no champion stun — it is an add-clear/control exotic. Conditional Finality's intrinsic Unstoppable stun covers one lane, and freeze itself halts Overload regen and pins Barrier behaviour while you reposition. Slot a Barrier/Overload frame if an activity demands the third lane.

Stats & mods

Weapons 200 → Class → Health. Weapons is pure PvE damage stacked on top of Bakris + Rending + Surges; Class feeds the Dodge that arms the Bakris Shift; Health rides on Frost Armor + Hedrons, so it is the dump stat.

Archetype lean: a Weapons/Class helmet (Bakris) with gunner-favoured arms and legs.

Mods:

Boots: Stasis Weapon Surge ×2 (Stasis weapon damage straight onto Cryosthesia, stacking with Bakris + Rending) · Stasis Scavenger.
Arms: Sidearm Loader / Sidearm Dexterity · Heavy Handed (melee kills refund Withering Blade).
Chest: resistance mods to taste under the Frost Armor layer.
Class item: Powerful Attraction (Dodge vacuums the shards/orbs Conduction is already pulling) · Bomber/Outreach for ability uptime.
Surge: Stasis Surge ×2 on legs, matched to Cryosthesia's element.
Anti-Champion: none needed on Cryosthesia itself — Conditional Finality provides Unstoppable; add an Overload/Barrier frame in the third slot if the activity demands it.

Artifact — Slayer Baron Apothecary Satchel

The Stasis artifact, built for exactly this loop: it converts Stasis weapon hits and shatters into Frost Armor and Stasis Shards, then pays those shards back as class-ability energy to re-arm the Bakris Dodge. Champion coverage stays bought (Conditional Finality's Unstoppable + freeze); the artifact's job is to thicken the freeze → shatter → shard economy.

Picks (2/3/2):

Tier 1: Wind Chill · Crystalline Converter
Tier 2: Hail The Storm · Frost Renewal · Curative Orbs
Tier 3: Served Cold · Brain Freeze

Wind Chill grants Frost Armor on rapid Stasis hits and makes Stasis Shards on hits versus slowed/frozen targets — Cryosthesia feeds both sides of it.
Crystalline Converter primes your next Stasis final blow to drop a Stasis Shard after a class ability, and you Dodge constantly for the Bakris Shift.
Hail The Storm makes shattering frozen targets and crystals deal bonus damage and release shards — this directly amplifies the catalyst loop.
Frost Renewal burst-freezes nearby foes and grants more Frost Armor when you take crit damage while armoured — more freezes to shatter, more DR.
Curative Orbs turns a shield break into an Orb of Power, feeding the Bonds/Bakris orb economy.
Served Cold refunds class-ability energy when you pick up a Stasis Shard — Grim Harvest + Conduction pump shards, so the Dodge keeps coming back.
Brain Freeze makes frozen combatants emit a chilling fog that slows others, extending the freeze-lock across a cluster.

Where it shines

Add-dense PvE — Vanguard Ops, Nightfalls, GMs, seasonal activities. Freeze a cluster, shatter it with a Rending-buffed charged shot, mag refunds, repeat. A control primary that also clears.
PvP duelling (off-meta but real): the charged shot is a one-tap-to-freeze setup into a guaranteed follow-up, and the Bakris Shift cloaks the engage.
Weakest at single-target boss DPS — it is a control primary, not a damage dealer. Let Conditional Finality or a Heavy do the boss work; Cryosthesia handles the room.
Champion coverage: Cryosthesia stuns nothing intrinsically. Conditional Finality's Split Decision is strong against Unstoppable; freeze halts Overload regen and pins Barrier for a reposition. Bring a Barrier/Overload frame for the third lane.

Corrected: paired weapon No Time to Explain was mislabelled "(Stasis Pulse)"; `data/weapon_facts.json` confirms it is a Kinetic Pulse Rifle (Primary, 340 RPM). Fixed to "(Kinetic Pulse)". Its Rewind Again perk still returns rounds vs Stasis-slowed/frozen targets (`exotics.md` l.281), so the synergy stands.
