Kuva Weapons

Main article: Kuva (Variant)

Kuva weapons are a special variant of existing weapons carried by a player's Lich and can be acquired once the Lich is Vanquished. If the player has enough weapon slots, they can claim these weapons from their Foundry, bypassing the supposed Mastery Rank requirement on these weapons. The weapons vary in attributes, dependent on the Lich the player has slain. The Energy Color on the weapon is depicted by what elemental bonus was augmented on the weapon during Lich creation and the progenitor Warframe. All weapons have an equal chance of spawning from a Kuva Lich.

 Kuva Drakgoon - Shrapnel projectiles do not slow down after ricocheting; bigger magazine and shorter reload time.

 Kuva Hind - Overall improved stats but longer reload time; additional firing mode in automatic fire.

 Kuva Karak - Shorter reload time, lower recoil, and greater accuracy.

 Kuva Kohm - Higher rate of fire.

 Kuva Ogris - Fires semi-automatically (instead of the charging trigger); smaller magazine, but greater damage.

 Kuva Quartakk - Fires single shots in full-auto when fired from the hip; semi-auto fires four shots simultaneously while aiming; shorter reload time.

 Kuva Tonkor - Shorter reload time, higher critical and status chance, higher base damage.

 Kuva Brakk - Higher rate of fire, magazine capacity, and shorter reload time.

 Kuva Kraken - Fires in three-shot (instead of two-shot) bursts; Alternate Fire shoots all remaining ammunition in the magazine in a quick burst; higher rate of fire, magazine capacity and shorter reload time.

 Kuva Nukor - Improvements to its already great critical multiplier and status chance; beam chains between multiple enemies.

 Kuva Seer - Projectiles have a small  Corrosive burst. Higher rate of fire, magazine capacity, and zoom factor.

 Kuva Twin Stubbas - Akimbo variant; higher rate of fire and magazine capacity.

 Kuva Hek - Alternate Fire fires all four barrels simultaneously.

 Kuva Grattler - No longer auto-spool and reaches peak fire rate instantly; doubled magazine size.

 Kuva Zarr - Drastically stronger cannon and longer-ranged flak shots.

Certain Kuva weapons are unique to Kuva liches, and are not based on existing Grineer weapons:

 Kuva Bramma - A massive bow that fires explosive arrows and clusterbombs, which can be detonated mid-flight.

 Kuva Chakkhurr - A flintlock-styled rifle with explosive shots and dealing increased headshot damage.

 Kuva Shildeg - A heavy hammer.

 Kuva Ayanga - A grenade launcher Arch-gun.

Mechanics

A Kuva variant of a weapon will only provide mastery points once. A second weapon of the same variant but with a different Lich name will not provide extra mastery. These weapons have a max rank of 40. To obtain the maximum rank, the player must polarize the weapon five times, with each Forma increasing the maximum possible rank by 2 (similar to  Paracesis).

The Kuva weapons additionally have bonus damage of one damage type, ranging from 25-60% of the weapon's base damage determined randomly, with lower percentages being more common. The damage type of this bonus damage is determined by the Progenitor Warframe, as per this table.

Note: This additional bonus damage applies as weapon base damage, meaning elemental mods and status that scale from base / modified base damage will be affected.

Valence Fusion

Main article: Valence Fusion § Kuva Lich/Tenet Weapons (edit)

Valence Fusion combines two of the same Kuva or Tenet weapons into one with a higher Elemental Bonus, multiplying the highest bonus of the two weapons by 1.1, capping at 60% bonus. Valence Fusion can be found under the Actions button while modding a weapon. After selecting Valence Fusion, a player is required to choose another of the same Kuva/Tenet weapon from the inventory (not in Foundry or with the Kuva Lich / Tenet Sister) to fuse it with. If the weapon's element bonuses differs, the player will be prompted to choose between the two available elements.

Any other properties (Orokin Catalyst, Forma, Stance Forma, Exilus Weapon Adapter, or Focus Lens) do not transfer over, meaning the order of fusion is important. Put simply, it is best to equip the weapon with the most resource investment (weapon rank, Catalyst, Forma, and Exilus that you wanted to keep) and fuse other weapons to it.

After selecting the donor weapon to be used in the fusion, a confirmation screen displays the desired weapon's new damage type and bonus values and warns that the transfer will consume the selected donor weapon. Players are then prompted to type FUSE to confirm the fusion.

• Example:  Kuva Kohm (A) has 40%  Heat Damage and an Orokin Catalyst. Kuva Kohm (B) has 52%  Radiation damage. The player has two options, to fuse (A) with (B) or to fuse (B) with (A).
  • Since 52% is higher than 40%, the result will always be according to the percentage of (B) and multiplied by 1.1, resulting in 57.2%.
  • Fusing (B) to (A): Equip (A), under Valence Fusion, select (B). The result of this will be a Kuva Kohm with 57.2%  Heat or  Radiation damage with an Orokin Catalyst. (B) will be destroyed.
  • Fusing (A) to (B): Equip (B), under Valence Fusion, select (A). The result of this will be a Kuva Kohm with 57.2%  Heat or  Radiation damage without an Orokin Catalyst. (A) will be destroyed.

Main article: Valence Fusion § Extra Math (edit)

For Weapons and same-tier Armaments, maximum % bonus (60%) can be achieved in the following number of fusions:

Minimum Initial Value	Maximum Number of Fusions
54.6%	1
49.6%	2
45.1%	3
41.0%	4
37.3%	5
33.9%	6
30.8%	7
28.0%	8
25.5%	9
25.0%	10

For example, a  Tenet Envoy with a 43% Toxin bonus will need at most 4 Fusions to reach the maximum element bonus of 60%.

Ephemera

Kuva Liches have a 20% chance to be created with an Ephemera equipped that corresponds to the Progenitor Warframe that killed them. These Ephemeras can be equipped on Companions, Archwings, Necramechs and K-Drives. If the Kuva Lich has an ephemera, the player will receive it regardless if they kill or convert the Lich.

	Vengeful Shockwave

	Vengeful Chill
	Vengeful Charge
