Scourge

The Scourge is Harrow's signature Speargun, firing fully automatic projectiles that explode and damage nearby enemies in a small radius. The Scourge can be thrown as Alternate Fire, inflicting a Bullet Attractor field on the heads of all enemies near the impact point.

Characteristics
This weapon deals damage on its primary fire and primarily high  damage on its alt-fire.

Advantages:
 * Deals damage - effective against Ferrite armor and Fossilized health.
 * High damage on alt-fire - effective against shields.
 * Primary fire impacts on enemies or surfaces causes an explosion that damages all enemies in a small radius.
 * Does not deal self damage to the user.
 * Explosion effect is able to bypass Arctic Eximus and Nullifier Crewman bubbles, damaging enemies keeping refuge within.
 * Alt-fire throws the Scourge to deal damage and cause Bullet Attractor-like fields on the heads of enemies near the impact point, allowing easier headshots with secondary weapons.
 * High ammunition capacity.
 * Very ammo efficient.
 * Very high status chance.
 * Can reach 100% status with, , , and.

Disadvantages:
 * Projectiles have travel time.
 * Slow fire rate.
 * Slow reload speed.
 * Once the Scourge is thrown, the player will not be able to use it until it is either picked up or when it returns to the player's hands after 20 seconds.
 * Extremely low critical chance on both primary fire and thrown spear.
 * Secondary fire deals self damage to the user, and may also self-proc any modded status effects.
 * Primary fire cannot deal, , and damage; does not benefit from mods that increase these damage types.

Tips

 * Using dual-stat elemental and status chance mods, such as and, can make Scourge achieve 100% status chance.
 * With its innate Corrosive damage that is effective against heavily armored targets like the Grineer, it is possible to add two more elemental damage types to maximize its status-based damage potential (such as adding damage against the Infestation &mdash; and to some extent, against other enemies because of its  gas procs &mdash; and  damage against Corpus robotics to make Scourge a versatile weapon against most enemy types).
 * The above Corrosive-Gas-Magnetic build on the Scourge is found to be surprisingly effective at dealing with Nullifier Crewmen, as the procs can bypass through the nullifier bubble and deal direct damage on the crewmen themselves (this was tested on a lvl100 Nullifier Crewman in the Simulacrum).
 * Primary fire bypasses Frost´s Globes from both sides.
 * works on this weapon while it is in a thrown state.

Trivia

 * A Scourge refers to a whip with multiple thongs or "tails" (a Cat o' nine tails being a good example), and was often used for corporal punishment as well as for self-flagellation by religious penitents. In contemporary terminology, the term has been applied to people, groups, or events that resulted in great calamity.

Bugs

 * could be used to allow the projectiles to stick then explode, but this feature was disabled, making the mod do nothing when equipped.
 * Has a high chance of disappearing when thrown.
 * This bug can be fixed by switching to an item such as Codex Scanner or entering a Bleedout state.
