Despair

"Used by the Stalker, DESPAIR throwing blades have a mono-filament edge, sharp enough to penetrate a warframe."

- In-Game Description

Characteristics
Advantages:
 * Silent.
 * Appears to be capable of higher ranges than the Kunai. (needs confirmation)
 * Deals Armor Piercing damage.
 * Deals 50% more damage to medium Grineer units.
 * Ignores armor calculation of Infested Ancients and other enemies.
 * Can penetrate straight through enemies, allowing it to hit multiple enemies if lined up (Bugged, only seems to work when you are host. Lag makes it work incorrectly).
 * Like the Kunai, the Despair has two polarity slots ideal for Hornet Strike and Barrel Diffusion for maximum damage.
 * Higher base damage than the Kunai.
 * Very fast reload speed.
 * Fully automatic.
 * The arc of each throw, although random, still allows you to accomplish headshots on enemies behind cover.
 * Infested Runners do not explode on death when killed by this weapon.

Disadvantages:
 * Only deals half damage to light Infested units.
 * Non-hitscan weapon. Projectiles have travel time, unsuitable against moving targets at long distances.
 * Trajectory can be inconsistent, making longer ranged throws more difficult.
 * Alongside the trajectory being inconsistent, though it is listed as 100% accurate, the Despair has a random, although tight spread with every throw.
 * The knife will always hit exactly where the users target reticule is lined up with; the vector it takes to get there may differentiate.
 * Requires an even larger amount of materials to craft compared to the Kunai.
 * While you are holding this weapon, your Slide Melee attack does not get a speed boost (bug).
 * Does not stagger like the Kunai.

Acquisition
The Despair's blueprint cannot be purchased on market, but it is included in the What Stalker? bundle. The blueprint can also be acquired from the Stalker.

Weapon Loadouts
See the user build section for builds using this weapon.

Tips

 * Using the Pistol Ammo Mutation mod can help regain lost ammo when needed.
 * Alternatively, bring along pistol ammo boxes.

Bugs

 * Currently, while holding a Datamass, there is no proper "animation" or "alignment" of the Despair, for running with the Datamass. The Despair will float above/outside of your warframe's hands, as if you had a pistol in your hand instead.
