Kuva Lich/Gameplay

==Strategy==
===Drawing out the Kuva Lich===
To fight a Kuva Lich, the player must draw them out. To do this, nodes that the Lich has influence over must be completed and their Thralls destroyed. A Lich will also have specific resistances and immunities that are unique to the player. The player will know a Lich is after them when an icon appears in the Navigation and Menu screens. This icon will appear beside the Nightwave button and will allow the player to check details about their Lich, including Lich Level, Requiem Mod attempts, and more.
Kuva Influence will be shown as a red cloud on the Navigation screen. It will start on one planet, clicking it in to view it will show which nodes the cloud is spreading over. These nodes will give the option to run the standard node mission, the Kuva Lich version, or any other active special version, such as Nightmares or Invasions. Kuva Liches can have Influence over nodes under other faction's control, making the thrall mission become similar to Crossfire missions.
Endless missions in Lich controlled territories only feature one "round", with Defense lasting five waves, Survival lasting five minutes before extraction is called, Interception lasting one wave, and Excavation requires 500 Cryotic before extraction is called. Defection and Mirror Defense missions are unavailable and are replaced by Exterminate.
Only one Kuva Lich can be after the player at any time, so the current Lich must be defeated before a new one can be made by the player.
===Requiem Murmurs===
To determine which Requiem Mods are needed to defeat the Lich the player will need to gain Requiem Murmurs. A multitude of Requiem Murmurs will update the Lich's status screen, revealing part of the Requiem Mod combination that will prove fatal to the Lich.
Note that Murmurs will only reveal the Requiem Mods required to kill the Lich, not the order they are needed to be in. The player will need to figure out the order by trial-and-error.
Any mission under a Lich's influence will periodically spawn Thralls as the squad advances through the mission. Killing a Thrall via a Mercy Finisher will reward all players in the mission one Requiem Murmur. Testing a Requiem Mod on a Lich also rewards Requiem Murmurs. If a mod is guessed incorrectly the entire squad gains 10 Murmurs. If a mod is guessed correctly the accumulated Murmurs will transfer over to the next mod reveal.
If a player joins a mission mid-progress, all killed Thralls and repelled Liches are instantly added to the Murmur progress.
===Combat===
If a Lich is sufficiently enraged, there is a chance they will appear in the mission for combat. It is entirely possible that a Lich will appear long before the player has deduced all three Requiem mods; because of this, killing or even fighting the Lich is not required for mission success (for example, waves in Defense missions will end even if the Lich is still active).
A Lich has a shield bar and three health bars. Depleting a Lich's health bar to 5% will cause them to stumble and begin to gradually recover health for 10 seconds, giving the player a chance to use their Parazon for a Mercy attack. If the Requiem mods are in the correct sequence, the Lich's health bar will be destroyed, otherwise, the Lich will simply despawn and also gain a rank up. Rank 1, 2, 3, and 4 Liches will respectively drop 150, 200, 250 and 300 for all squad members when a Parazon is used on them.
In addition to having , , and health types, Liches have variable resistances and weaknesses to damage types. A Lich can can have a weakness (+25% damage), resistance (-50% damage) or immunity (-100% damage) to a particular damage type. As a Lich levels up, the type against which it is vulnerable to may become one of those it resists. Unlike most bosses, Kuva Liches are vulnerable to status effects with some restrictions; they can only receive up to 4 stacks of any status effect with the exception of which can stack up to 6 times, and only amplifies the damage the Lich receives from allied units and does not enable friendly fire unless those allies themselves are inflicted by the status. While their shields can be removed, its armor cannot be stripped. Finally, it possesses Damage Attenuation which resists high damage weapons, which is especially more noticeable at higher ranks.
If a Lich stumbles three times without attempting to use the Parazon on the Lich, or all Tenno are in bleedout or are dead, it will automatically flee and leave the mission. This prevents it from leveling up, but will not drop Kuva nor generate Murmur knowledge.
Only one Lich can be present at any given time. The present Lich must be repelled or defeated in order for another player's Lich to spawn.
===Final Confrontation===
When the right combination of Requiem Mods is found and all three of the Lich's health bars have been destroyed, all the Requiem mods used will lose one charge and the Lich will have a 25% chance to drop the Requiem Mod Oull for only their player before retreating to the Saturn Proxima, appearing in a node dubbed "Kuva Lich Confrontation". This is an Empyrean Skirmish mission where players must embark in their Railjack and eliminate a number of fighters and Gokstad Crewships before they board a Grineer Galleon for the final confrontation with the Lich. If there are multiple squad members, each player's Lich will spawn in one-by-one until all of them are defeated.
The Lich in the final confrontation only has one large health bar. Once depleted, the Lich will be finally defeated for good and prompt one final Mercy. The player will be given two choices: Vanquish the Kuva Lich or Convert it.
*Whichever choice made, all "stolen" drops that they were responsible for will be returned to the player. If the Lich has an Ephemera equipped, the player is also guaranteed to get it. There is also a 25% chance the Lich will reward a Requiem Ultimatum for only their player.
*Vanquish: The Lich will permanently die and award the player their Kuva Weapon, which is also named after the defeated Lich (e.g. "Ulogg Stakk Kuva Quartakk"); it will be "Ready to Claim" in the Foundry and bypasses its Mastery Rank requirement.
*Convert: The Lich becomes the player's ally, allowing it to appear randomly in a mission after the player enters bleedout, and can be brought aboard Railjacks as defensive Crew.
**The player can trade a converted Lich, allowing another player a chance to earn their weapon and/or Ephemera. The trade is performed inside a Clan Dojo's Crimson Branch room, and the recipient must not have any active Lich.
***The stats of the Lich being traded can be previewed by right-clicking its token.
***Once traded, the Lich will become the recipient's active Lich, and the Requiem Mod combination used to defeat them will change.
***A converted Lich can only be traded once. If the recipient converts their received Lich, it will not be tradeable.
The player has 20 seconds to choose. If no choice is made, the Lich is automatically vanquished.
===Summary===
#Play missions controlled by your Kuva Lich and kill their Thralls to get closer to finding out their Requiem Mods sequence.
#Farm Requiem Mods by opening up Requiem Relics during Kuva Fortress Void Fissures. Requiem Relics can be dropped by Kuva Thralls and Kuva Siphons.
#Equip these Requiem Mods to your Parazon in any desired order to test out the sequence against your Lich.
#Keep playing on Lich-controlled nodes and farming Thralls until you encounter your Lich.
#Lower its health to 0 and attempt to finish them with your Parazon. If the Requiem order is incorrect, the Parazon attempt(s) will stop at the first incorrect mod. The Kuva Lich will then level up, controlling more planets and nodes in the Star Chart.
#Reorder or change the Requiem mods installed on your Parazon depending on newly gained info.
#Repeat until the Requiem sequence is complete, and all Requiem Mods used in the sequence will lose one charge. The Lich will retreat to the Saturn Proxima in a Skirmish mission for one final confrontation. Once defeated there, all stolen drops are returned, and its Ephemera (if it has one) is rewarded. Choose to Vanquish and acquire the Lich's weapon, or Convert to turn it into an ally that randomly appears in missions or to trade it to another player.
==Tips==
*Although Kuva Liches are unlockable as early as Mastery Rank 5, it may be wise to hold off on creating a Lich until you have a more varied arsenal; assuming players only do the bare minimum of mission nodes and Junction requirements required to access The War Within, reaching Mastery Rank 5 only takes four fully-ranked Warframes and eleven fully-ranked weapons with an additional 10 levels in another, which is likely to be a very insufficient arsenal for taking down a Lich, particularly considering what is available to players up to and at Mastery Rank 5.
**If you feel that you won't be able to handle a Kuva Lich, simply do not mercy kill any Kuva Larvlings that appear.
*When a Kuva Lich invades a mission, they will randomly convert any enemy around (including Latchers) into a Thrall. This can be used to "farm" Requiem Murmur fragments up to the mission's Thrall cap. However this process requires enemies alive around the Lich, so care must be taken. Invisibility is a plus at this point as sneaking around the Lich while farming thralls will be much easier.
*Killing 5-20 enemies triggers the creation of a thrall in most missions. Especially for solo hunters, instead of killing every enemy immediately, you can stop killing and focus on the thrall alone, then continue for another 5-20 enemies. Because mostly only 1-2 thralls will be active at a time throughout the map (unless a Lich is active) and a thrall is only converted from an enemy readily on the map.
**In Survival missions, the hunt may continue until the air support reaches to 0 and all enemies are dead.
*A safe 4 attempt run would entail the following:
*#Collect murmurs until the first hint is acquired, do not mercy the Lich until then. Equip the known requiem mod in the first slot, and the remaining two slots being random. If this fails, move it to the second slot.
*#Collect murmurs until the second hint is acquired. Equip this new requiem mod into the soonest unknown slot (the first slot if the above step was unsuccessful, otherwise the second slot). If this fails, move it to the third slot. If this is successful, and your second slot fails, move the second slot to the third instead.
*#Repeat the above steps for the third hint and slot. By this third attempt, you should have revealed your first slot, making the second and third slot unknown in the worst-case scenario, which only requires that you swap them for your fourth attempt, guaranteeing the kill.
*Safe 4 attempt run with Oull:
*#Collect murmurs until the first hint is acquired, do not mercy the Lich until then. Equip Oull in the first slot and the known requiem in the second, and if it fails swap them around.
*#Continue to collect murmurs. If the first known requiem fails the first slot, move it to the third slot.
*#Collect murmurs until the second hint is acquired. Equip this new requiem mod into the soonest unknown slot (the third slot, or the first slot if the first two steps were unsuccessful). If this fails, move it to the second slot.
*#If all the above steps were followed and the Lich is still not defeated, this final mercy will guarantee the sequence. If the third hint is revealed before then, replace Oull with it.
*Due to their Damage Attenuation, weapons with low base damage such as high fire rate rifles or high multishot shotguns are more effective than weapons that deal high damage in a single shot.
*Liches are vulnerable to Warframe abilities. In particular, 's inflicts significant damage that bypasses their Damage Attenuation and 's (Helminth subsumable) drastically slows them down.
==Trivia==
*The chance of downing a Kuva Lich on the first try assuming the player has at least three Requiem Mods installed is a 1/336 (0.2976%) chance. This can be improved to a 1/56 (1.7857%) chance with an Oull Mod.
