Acrid

The Acrid is a Grineer weapon unlockable through Bio Lab Research in the dojo. It is a toxic weapon system that delivers toxin-filled flechettes, rather similar to the rounds from the Boltor.

This weapon can be sold for.

Characteristics
This weapon deals primarily damage.

Advantages:
 * Innate damage.
 * 25% bonus damage to Ferrite Armor - effective against Grineer units equipped with it.
 * Toxic damage ignores Shields and deals 50% bonus damage to Flesh - effective against Corpus.
 * Has 100% proc chance on each hit, which occurs in addition to procs from the weapon's status chance.
 * Fast reloading speed.
 * High rate of fire.
 * Perfect accuracy.
 * Decent ammo efficiency due to the damage over time effect.
 * No recoil.
 * Can use the Acrid-exclusive Toxic Sequence mod.

Disadvantages:
 * Needles have a travel time.
 * Delay and small size of the needles can make it difficult to hit moving targets at a distance.
 * Damage cannot be increased with, or  mods.
 * May take time to completely kill enemies, if relying on DoT.
 * DoT is only affected by base damage (adding elemental damage will not increase it)
 * damage deals less damage to Robotics, Machinery and Fossilized.
 * Low critical chance.

Tips

 * Semi-automatic firing can be countered by simply adding an alternative way of firing on 'scroll up' or 'scroll down' through the key binding customization.
 * Getting headshots will not only double the damage of the weapon, but double the resulting damage ticks as well.
 * Toxic Sequence can cause proc length to double; stacking shots quickly on enemies will cause their health to quickly succumb to thousands of damage a second, with players able to stack many shots at once before the first damage tick expires.

Trivia

 * Before, equipping Saryn, Mire, Torid and Acrid would give you the only loadout consisting solely of toxin-based attacks.
 * As of the Acrid is physically the largest handgun in Warframe.
 * One definition for "acrid" is "sharp and harsh or unpleasantly pungent in taste or odor", likely owing to the gun's toxin-based damage.
 * The Acrid has written in Grineer near the barrel, this translates to "Obey".
 * Inside of a Chem Lab, a holographic Acrid can be seen, similar to many other Grineer weapons.
