Lynx

The Lynx is a miniboss that is encountered in certain Orokin Sabotage tiers that feature Corpus enemies, acting as the main miniboss from which the mission's Void Key drops from. It resembles a smaller Jackal with blue armor, and has the ability to deploy Osprey drones and Turrets to assist it in combat.

General
Lynx is invulnerable to damage while there are Osprey drones around it - you need to quickly destroy them before it can spawn more in order to damage it.

Utilizing Warframe Abilities

 * Mag's Pull can be used to quickly destroy the Lynx Ospreys as they stay relatively close to each other.
 * Ash and Loki can use Smoke Screen or Invisibility respectively to dispose of the drones and the boss itself while avoiding all of the damage.
 * Nyx can use Chaos to disable the Lynx's immunity provided by the drones.
 * Rhino's Rhino Stomp can easily destroy all the Lynx Ospreys around the Lynx as well as preventing from fighting back or summoning more Ospreys or Turrets, rendering it defenseless until the stun duration has passed.

Trivia

 * The Lynx as a whole is a call back to the Hyena Pack prior to their revamp in Update 12, which was essentially a single, scaled-down Jackal rather than a pack of uniquely designed machines.
 * Lynx is a genus for the species of medium-sized cats, between the sizes of lions and tigers to domesticated house cats.
 * The Lynx also appears in the Archwing quest because one of the missions takes place in the Orokin Void, stopping the Corpus from getting into the Void.
