Stug

The Stug is a Grineer pistol that deals Corrosive damage and was released in Update 11.5. It has a similar firing mechanism to the Ballistica; a quick tap fires a single weak "blob" and holding down the firing button creates a larger, stronger blob.

Characteristics
This weapon deals damage.

Advantages
 * High Corrosive damage.
 * Very effective against Ferrite Armor.
 * Charge can stack up to 6 blobs (uses 6 ammo).
 * Area-of-Effect damage. 48.16% of base and any elemental damage will be used for the AoE damage.
 * Blobs do damage over time.
 * Blobs stack when shot onto each other, increasing detonation time and damage.
 * Blobs will adhere firmly to enemies.
 * Fast manual firing rate.
 * Explosions deal Status proc.
 * A polarity slot.
 * It's possible to commit suicide with this weapon, in order to let a teammate resurrect you with full health when low.

Disadvantages
 * Very slow charge rate.
 * Unable to deal critical hit.
 * The steep arc and the low projectile speed severely limits accuracy. Also renders this weapon useless against long-ranged target. (However, the steep arc can be utilized to kill enemy units behind cover)
 * Can deal self-damage and Status proc to the user. The more blobs that are stacked, the more damage you will take.
 * Has very small explosion radius that does not increase when stacking blobs.
 * Blob cannot stack more than six blobs, if extra blobs are shot onto a full blob, it will stack but not increase damage.
 * Lephantis is 100% immune to this weapon due to explosions affecting the body rather than the weak points.

Tips

 * Stug explosions can deal headshot damage when triggered above their targets, this also includes the blobs themselves hitting heads.
 * Barrel Diffusion and Lethal Torrent will allow the Stug to build up blobs much faster, while the Lethal Torrent can increase firing and charging speed of the weapon.
 * It is not advisable to fight enemies in close range with this weapon, as it deals damage to the user, especially when equipped with Pathogen Rounds. The more blobs that are stacked, the more damage you will take.
 * The Stug can have three unique combination elementals, with Corrosive already provided, allowing Pathogen Rounds and Convulsion mods to be equipped separately for such combinations.
 * The Stug's shots will not just stick to enemies, but other players too. This lets you put them on another player for a little bit of quick melee defense (similar to Vauban's Teslas, but much shorter lived). Also the shots will stick to Loki's Decoy (and Saryn's Molt?) for a nice little trap.

Trivia

 * The Stug is the third of three very large secondary weapons. The first two would be the Acrid and the Ballistica.
 * "Stug" is likely taken from the WW2 German assault gun of the same name; this makes it the second Grineer weapon named after a military vehicle, the first being the Hind.
 * The Stug is clearly inspired by the Bio-rifle from the Unreal Tournament series, as it functions almost identically, thanks to its firing modes (shoot a single glob, or charge for a larger projectile) and projectile behaviour (slow and heavy, adheres to surfaces, delayed explosion).
 * This is the second secondary weapon that has a Charge ability.
 * While the game startup window (The one that lists recent updates) refers to the Stug as a Goo-gun, the shop calls it a Gel gun.
