Kuva Lich

The Kuva Lich is a new enemy in Warframe. Introduced with Update 26, The Old Blood, the Kuva Lich is an enemy that hunts you down and invades the system, and there's nothing you can do about it because your melee weapon is fucking garbage in the new Melee update. They are difficult to kill, you are the only Tenno who can kill your own Kuva Lich, and you will need the new Parazon weapon to do it.

How To Find A Kuva Lich
To find a Kuva Lich, you must first kill a Kuva Larvling. These can be found in any regular level 20+ Grineer mission in the Origin System. Personally I just ran the Capture mission at Cassini until one appeared. This does not include Sorties, Fissures, Quests or Special Regions. You will also need to have completed The War Within, as it is a prerequisite for the Kuva Lich based content.

The Kuva Larvling will spawn into your mission as you play and will have a red waypoint on the screen. Just follow the waypoint, kill the Larvaling, and then your Kuva Lich will be created in retaliation. You can then finish out the mission as normal. When you have finished the mission, and back on your ship, the Lich will start to talk to you. Your Lich is unique, with its own name, stats, and weapon.

How To Fight The Kuva Lich
To fight your Kuva Lich, you must draw them out. You do this by doing missions in Nodes that the Lich has influence, and by destroying their Thralls. Killing the Thralls using the Parazon will give you clues on the correct order of Requiem mods that you need to kill your Lich. Your Lich will also have specific resistances, and immunities, that are unique to you.

You will know a Lich is after you when an icon appears in your Navigation and Menu screens. The icon will appear beside the Nightwave button and will allow you to check details about your Lich, including Lich Level, Requiem Mod Attempts, and more.

Kuva Influence will be shown as a red cloud on your Navigation. It will start one destination, and when you click in to view it, you will see which Nodes the cloud is spreading over. Nodes, where the Kuva Lich has Influence, will have a Reward Tax. The Lich will steal parts of your loot! The good news is, once you kill the Lich, all that loot is returned to you.

These Nodes will give you the option to run the standard Node mission, the Kuva Lich version, or any active special version, such as Nightmares or Invasions.

How To Kill A Kuva Lich
Only one Kuva Lich can be after you at one time, so you need to kill them outright to get a new one. To kill a Lich, you need to use your new Parazon with Requiem mods. The Requiem Mods form a sort of puzzle and must be in the correct order to deliver the killing blow. Your squad can weaken the Lich, but only you may kill it.

To figure out the combination, you will need to kill the Lich's Thralls. To do this, play the special missions on the Nodes where the Lich has influence. As you play, Thralls will spawn. Fight them as normal, then when they fall over with the red symbol above them, run up and interact with them to delivery the Secret Mercy Finisher. This will get you a Requiem Murmur. You need to kill the Thralls, and clear the Nodes, to progress towards figuring out which Requiem Mod combination will prove fatal to your Lich. Thralls seem to be quiet common, I had 9 of them spawn in one Extermination mission.

When you finally find the right combination of Mods, you will have two choices. You can kill the Kuva Lich, or decide to Convert it. Killing it will get you a Kuva Weapon, while Converting it will turn it to your side, and it can appear in fights beside you.

Kuva Lich Weapons
These weapons will be carried by your Lich, and can be gotten when you kill them. The weapons have custom stats and variants, depending on your specific Lich.

Kuva Karak: The custom weapon of a fearsome Kuva Lich. It has greater reload speed, lower recoil, and greater accuracy than the standard-issue Karak rifle.

Kuva Quartakk: Unlike a standard Quartakk, this Kuva Lich variant fires automatically from the hip and reloads faster while retaining its signature feature: annihilating targets with four simultaneous shots.

Kuva Ogris: The custom weapon of a fearsome Kuva Lich. Unlike the basic version the Kuva Ogris fires detonite-infused casings semi-automatically, from a smaller clip, while dealing greater damage per shot.

Kuva Kohm: The Kuva Kohm variant has a higher fire rate than the original. For every shot fired in rapid succession, the Kuva Kohm releases an additional bolt and grows more lethal.

Kuva Tonkor: This Lich-variant grenade launcher hurls mayhem and destruction with an increased reload speed.

Kuva Drakgoon: The Kuva Drakgoon flak cannon sends volleys of intensely hot shrapnel ricocheting around the room that do not slow down. Larger clip size and reload speed. Can be fired in wide or concentrated bursts.

Kuva Stubba (AKA Twin Stubba): Double-fist rapid-fire bursts of pain with these dual-wield variants of the Grineer submachine gun. Higher fire-rate and clip capacity.

Kuva Seer: This variant pistol has higher fire rate and magazine capacity. Superior zoom capabilities, plus projectiles have a small Corrosive burst.

Kuva Kraken: A custom variant that fires three quick shots with a single pull of the trigger, or can alt-fire burst the remainder of its clip. Higher fire rate, magazine capacity and reload speed.

Kuva Brakk: This Lich-variant semi-automatic hand cannon delivers a lot of punch in a small package. Higher fire rate, magazine capacity, and reload speed.

Kuva Chakkhurr - A high-damage flintlock rifle that does additional Damage on head shots!

Kuva Shieldeg - A massive hammer for the smashing!!
