Riven Splicers are earned exclusively from The Icebind, with one guaranteed on successful completion. A Splicer combines two compatible traits on a Riven into a selected spliced trait plus a random replacement trait. The spliced trait stays locked during cycling, and that special lock alone does not double the Kuva cost.

Riven Splicing launched with Update 44.1.0 on October 7, 2026. Hotfix 44.1.1 corrected an unintended doubling of cycling cost and a Weak Point Damage issue. The rules here reflect those inspected notes, checked October 13; they supersede launch previews that still called Splicing a future feature.

01

Get a Riven Splicer first

The documented source is The Icebind, the six-player mission accessed through Cephalon Melica at Yuvan Peak. Completing the mission grants the Splicer. Optional side objectives produce Frozen Keys for additional chests, but the basic Splicer reward is attached to mission success.

Use the Icebind guide for prerequisites, Cryobells, and the mission process. The important planning distinction is that Splicers are limited by access to successful Icebind runs. Do not assume that buying regular Kuva, farming Entropic Eximus, or opening any Riven-related reward automatically produces a Splicer.

02

Open the Splicing menu and inspect compatibility

Select a Riven Mod and open its Riven Splicing menu. The interface lists your Rivens and distinguishes those with compatible trait combinations. Select an eligible Riven to inspect the available results. Show All Possible Splices explains the pairs supported for that Riven, while Change Selected Trait lets you choose when several splices are possible.

Compatibility depends on the actual traits already on the same Riven. Owning two separate Rivens with one ingredient trait each is not the process described by the official system. The operation combines traits on the selected Mod; it does not combine two entire Riven cards into one.

Before confirming, read the intended spliced result and both consumed traits. The chosen special result is known in advance. The extra replacement is random, so you are not choosing a complete finished roll merely by choosing the splice.

03

Elemental and faction combinations

These pairs are listed for all Rivens in the official Splicing notes. The in-game preview remains the final check for your selected card and its available combinations.

Desired spliced traitRequired trait pair
Gas DamageToxin Damage + Heat Damage
Corrosive DamageToxin Damage + Electric Damage
Viral DamageToxin Damage + Cold Damage
Radiation DamageHeat Damage + Electric Damage
Blast DamageHeat Damage + Cold Damage
Magnetic DamageElectric Damage + Cold Damage
Damage vs OrokinDamage vs Corpus + Damage vs Grineer
Damage vs TechrotDamage vs Corpus + Damage vs Infested
Damage vs ScaldraDamage vs Infested + Damage vs Grineer

An elemental combination is not automatically the best choice for every weapon. Consider the weapon's full elemental arrangement and the enemies you intend to fight. The trait table identifies legal combinations; it does not establish a universal damage ranking or the best result for your particular Riven.

04

Ranged-weapon combinations

The official ranged category includes Rifle, Shotgun, Pistol, Kitgun, Archgun, and selected Companion Rivens.

Desired spliced traitCompatible pairs
Weakpoint DamageDamage + Zoom; or Damage + Multishot
Weakpoint Critical ChanceCritical Chance + Zoom; or Critical Chance + Multishot
Ammo EfficiencyMagazine Capacity + Reload Speed; or Weapon Recoil + Ammo Maximum
Magazine Reload While HolsteredAmmo Maximum + Reload Speed; or Ammo Maximum + Magazine Capacity
Status DamageDamage + Status Chance

Read these as alternatives where two pairs are shown. You do not need all four ingredient traits to obtain the result. Also consider what you remove: exchanging a useful original trait for a conditional result may change the weapon's behavior even if the new line looks impressive.

05

Melee-weapon combinations

The official melee category includes Melee, Zaw, and selected Companion Rivens.

Desired spliced traitRequired trait pair
Heavy Attack DamageHeavy Attack Efficiency + Additional Combo Count Chance
Heavy Attack Windup SpeedHeavy Attack Efficiency + Combo Duration
Parry AngleAttack Speed + Range
Slam DamageMelee Damage + Attack Speed
Status DamageMelee Damage + Status Chance

Match the result to your attack pattern. A Heavy Attack or Slam result deserves a different evaluation from a general melee configuration. This guide has not benchmarked specific Rivens and does not attach market values to any of these outcomes.

06

What happens to the two consumed traits?

The two ingredient traits are replaced by the chosen splice and one random trait from the normal cycling pool. That random result can include a trait that was just consumed. If both ingredients were positive, the replacement is positive. If one consumed ingredient was negative, the replacement is negative.

This preserves the Riven's positive/negative layout. After Splicing, the counts of positive and negative traits also remain fixed through subsequent cycles while the splice is present. For example, a card with three positive traits and no negative does not spontaneously become a three-positive, one-negative card simply because you continue cycling it.

That persistence is useful when you want to keep a layout, but it is a constraint when you want to change it. Evaluate the layout before spending the Splicer rather than focusing only on the name of the new special trait.

07

Spliced locks and normal trait locks

A spliced trait is automatically preserved during cycling. Its preservation does not itself count as the ordinary paid trait lock that doubles Kuva cost. You can also use the separate Trait Locking feature to preserve another trait, which gives you two retained traits while cycling the others.

The ordinary trait lock still has its own cost behavior. Read the displayed Kuva total before cycling, especially when combining the two systems. Update 44 also explains that an ordinary trait lock must be selected again after reopening its menu; do not assume a previous menu session guarantees the same choice now.

To remove a splice, unlock the spliced trait and cycle it away. The official notes describe this as the route to freeing the card for a new splice and changing its layout again. Do not treat removing the lock as a promised Splicer refund; no refund is established by these sources.

08

Work through one example before spending

Suppose your Riven contains positive Heat, Cold, and Toxin traits. The official example offers three possible splices: Blast, Gas, or Viral. Choosing Viral consumes the Cold and Toxin ingredients, creates the Viral trait, and rolls a new positive replacement. The remaining positive Heat trait is not the random slot in that operation.

The result retains three positive traits and no negative. Future cycling preserves Viral while the splice remains locked. If you additionally lock another trait with the ordinary system, account for its cycling cost separately. The example explains the transformation; it promises neither a particular random replacement nor a final numerical value.
