The Icebind Guide (2026): Warframe’s Six-Player Cryobell Mode, Formerly Glacial Defiance

Six-player Cryobell mode, formerly Glacial Defiance: rules, rewards, DE's drop rates

Last Updated on October 7, 2026

The short answer

The Icebind, announced as Glacial Defiance, is live. It shipped in Update 44.1.0 on October 7, 2026. It is a six-player Cryobell mode: exactly six Tenno, no duplicate frames, no public matchmaking, three clears a week. Every clear pays one Riven Splicer, a Kuva roll and one Crested Frozen Chest item, and each side objective adds a Frozen Chest. Narin’s parts still do not come from it: those cost Entropic Kuva from Zariman missions.

Reviewed October 7, 2026, current through Update 44.1 (The Icebind). Every number on this page has two sources; this page is re-checked after every major patch.

	What it is
Status	Live. Released October 7, 2026 in Update 44.1.0, two weeks after the Update 44 launch on September 23.
Where	Yuvan Peak on Earth. Talk to Cephalon Melica and pick Ring the Cryobell. Rewards are handed out in Melica’s Glacial Laboratory on the Zariman.
Players	Six Tenno, exactly, with no duplicate Warframes. No public matchmaking: the host invites a premade squad.
Requirements	Angels of the Zariman and Whispers in the Walls finished, plus Elite Deep Archimedea or Elite Temporal Archimedea unlocked (not cleared). No Mastery Rank gate.
Cryobells	Three form at each weekly reset (Sunday, midnight UTC). You can hold six. A bell is spent only when you extract successfully.
Difficulty	Enemy level 999+. Enemy health, shields and armor rise 200%, plus 100% per squad member, up to 800%.
Rewards	Every clear: one Riven Splicer, a Kuva roll (7,500, 17,500 or 100,000) and one Crested Frozen Chest item. Each side objective: a Frozen Chest with Kuva (1,750 to 7,500) and one item.
Weekly limit	Three clears a week. Failed runs do not count and do not burn a bell.

How a run works

Check the gates: Angels of the Zariman and Whispers in the Walls done, Elite Deep or Elite Temporal Archimedea unlocked.
Go to Yuvan Peak, talk to Cephalon Melica and pick Ring the Cryobell. Collect your three bells after each weekly reset.
Build a squad of exactly six with six different Warframes. There is no public matchmaking, so the host invites everyone.
Each player offers one Cryobell. Each bell is a random mission with a random faction, one Mission Bind, Tactical Binds and the owner's Personal Bind. The squad votes within 60 seconds; the host breaks ties, and no votes means a random pick.
Decide on the side objectives before you commit. Each mission has up to three (Lockbox, Cryothermia, Indomitable Ice, Entropy Orb, Signal Chain). Once one is active you cannot extract until it is done, and failing it fails the mission.
Clear the main objective and extract. Everyone gets a Riven Splicer and a Crested Frozen Key, plus one Frozen Key per side objective. Anyone dead for three minutes or more misses that objective's key.
Open your chests in Melica's Glacial Laboratory. A failed run spends nothing and does not count toward the three weekly clears.

Squad rules that kill runs

No self revive. Last Gasp starts draining 2 seconds earlier each time you use it.
A downed Tenno leaves a tombstone. Reviving them takes at least three living squadmates, each giving up part of their max health for a while. Each revive cuts the bleedout timer by 5 seconds, down to a floor of 5.
Every Restore type has a 3-minute cooldown. Companion recovery takes twice as long. Full shield gate immunity is halved.
Enemy health, shields and armor rise 200%, plus 100% per squad member, to a cap of 800%.

Binds: the modifiers

Mission Bind: one big modifier per bell, such as Entropic Overload, Stone Soldiers, Miasmic Militia, Thin Boundary or Inferno.
Tactical Bind: smaller twists such as Antimatter Foes, Bruised Shields, Archaic Armor or Heavy Warfare.
Personal Bind: a debuff tied to each bell's owner, such as Energy Exhaustion or Knifestep Syndrome (lose 2 Health when moving). It applies to that player whichever bell wins the vote.

What the mode does and does not give you

Reward	Comes from
Riven Splicers	Only from this mode, one per clear. Riven Splicing is live with it: two chosen traits merge into one fixed result, such as Heat plus Cold into Blast.
Cryobell Sumdali	DE's patch notes list it as the reward for your first clear.
Narin and her weapons	Not from the mode. Buy the blueprints from Cephalon Melica with Entropic Kuva.
Entropic Kuva	Not from the mode. It drops from Entropic Eximus in Zariman missions.

Entropic Eximus (the way to farm Narin)

Entropic Eximus can spawn in any Zariman mission, at a higher rate than other Eximus types, and they are the only source of Entropic Kuva.
They sit inside a nearly impenetrable shield bubble. DE's advice is to slip inside it and kill them from within.
Primary and Secondary weapon damage against them is reduced by 90 percent, so melee is the reliable way to kill them.
The Iceblade of Narin buff from Neote at Yuvan Peak lets melee hits break the bubble. The bubble breaking does not remove the damage resistance.
Since Update 44.1 they no longer spawn as Helions, so you no longer chase a flying one with a melee weapon.

Tips that save runs

Bring six different frames with real survivability. No self revive and a halved shield gate punish glass builds.
Make side objectives a squad call. One active objective blocks extraction, and a fail wipes the whole run's rewards.
A wipe costs time, not a bell. Retry the same Cryobell.
Farm Entropic Kuva in normal Zariman missions for Narin. The Icebind is for Splicers, Kuva and Shards, not her parts.

Mistakes that waste runs

Waiting for the mode to drop Narin. Her parts cost Entropic Kuva, not Icebind rewards.
Queuing for a public squad. There is none; the host has to invite five.
Staying dead. Three minutes down and you lose that side objective's Frozen Key.
Shooting Entropic Eximus from outside the bubble. Ranged damage is cut by 90 percent.
