Zarr

The Zarr is a Grineer heavy weapon introduced in The War Within update. Its Alternate Fire allows users to choose between firing a single explosive cannonball or a barrage of projectiles.

Characteristics
This weapon deals primarily damage.

Advantages:
 * High damage is ideal against Fossilized and Machinery.
 * High ammo reserves for a launcher.
 * Effective over multiple ranges due to its Alternate Fire;
 * Cannon mode is well suited for targets at a distance, or groups of enemies.
 * Bomblets increase explosive range and have status chance and critical chance independent of the main projectile.
 * Bomblets do not deal self-damage.
 * Barrage mode deals heavy damage to targets at close range.
 * Barrage mode has innate Punch Through.
 * High status chance.
 * Good critical chance.
 * High critical damage multiplier.
 * Reload can be interrupted by firing.
 * Has a polarity.
 * Can use the launcher-exclusive Firestorm and Adhesive Blast mods.

Disadvantages:
 * The main projectile fired in Cannon mode deals full self-damage.
 * Barrage mode is only usable at close range due to large spread and short effective range.
 * Draws from the rare sniper ammo pool.

Tips

 * The Zarr is unique in the fact that it can quickly switch to a close range function that has no chance of damaging the player, allowing it to be used in tight spaces safely.
 * While the Zarr has an average critical chance, the listed value is for each bomblet in Cannon mode, and each individual pellet in Barrage mode, which combined with the Zarr's above average critical damage makes a crit build viable.

Trivia

 * The word Zarr is a Swiss-German name derived from the Slavic word Tsar, a word used as a title for supreme rulers of eastern and south-eastern European countries.
 * The Zarr is visually and somewhat functionally reminiscent of a swivel cannon.
 * Upon release, the Codex entry misspelled "cannon" as "canon".
 * When stuck to surfaces with Adhesive Blast, it has a unique sound effect signaling to the player that they are stuck.

Bugs

 * Stuck cannonballs on enemies using Adhesive Blast will not damage the enemies over time. Only the initial impact and explosion will damage them.
