Tonkor

The Tonkor is a Grineer grenade launcher which fires concussion explosives that can launch its owner airborne. Compared to the Penta, the Tonkor has slightly less explosion damage and magazine size, but boasts a higher fire rate, faster reload, and good critical potential.

Characteristics
This weapon deals primarily damage.

Advantages :
 * Grenades deal damage when hitting an enemy.
 * High critical chance and good multiplier stats.
 * High AoE damage.
 * 325 damage that can be increased by mods.
 * Decent fire rate for a grenade launcher type weapon.
 * Can use the exclusive Firestorm mod.
 * Zooming will display the next grenade's trajectory.
 * Can be used to 'rocket jump' for the wielder exclusively.
 * Cannot be used to move Tenno-created allies from powers such as Saryn's Molt, Loki's Decoy, Chroma's Effigy.
 * Deals only 50 maximum damage to user regardless of mods.

Disadvantages :
 * Grenades have a relatively slow projectile speed and heavy arcing.
 * Grenades have a high bouncing capability which makes it hard to stack on a desired spot.
 * Small magazine size.
 * The grenades deal both and  damage on direct hits only.
 * Second lowest max ammo of all primary weapons.
 * Low accuracy.
 * Shooting at enemies that are close will force you to jump.
 * However, this can be used to chain to a melee slam attack, or other airborne offensive such as shooting your second shot underneath you.
 * Grenades will damage the player, albeit much less than the similar Penta.
 * Draws from the rare sniper ammo pool.
 * Unlike the Penta, the grenades cannot be detonated manually or prematurely, forcing the player to aim directly at enemies in most cases.
 * If grenades miss, stepping on them will cause them to detonate, dealing the same damage as usual.
 * Grenades have a long fuse time which may make crowd control more challenging.

Tips

 * Terminal Velocity will help increase its projectile speed. Trajectory guide when zoomed will adjust with increased flight speed.
 * Zephyr's Jet Stream increases the grenade projectile flight speed significantly.
 * Jet Stream with high Power Strength allows for the projectiles to explode on first ground contact. Along with a maxed Terminal Velocity and maxed Jet Stream, a minimum of 175% power strength is required to have this effect.
 * Without using Terminal Velocity, minimum Power Strength needed is somewhere between 234% and 236%, when using Jet Stream.
 * The Tonkor's self-damage property can be used to increase Vex Armor's buffs when using Chroma.
 * It is advised to not use punch-through, as it can cause the Tonkor's projectiles to hit enemies without exploding. It also causes the projectiles to bounce/penetrate surfaces unpredictably.
 * Grenades will immediately explode when impacting the following surfaces, allowing instant high damage to enemies:
 * Blunt, Bulwark, Decoy, Molt

Trivia

 * The Grineer text on the side of its barrel translates to "ANM".
 * The Tonkor's breech-loading design is derived from the M79 grenade launcher, albeit with the ability to hold two rounds instead of one.
 * Oddly, the Tonkor's reload animation appears to consist of loading one grenade instead of two.
 * It seems that these "grenades" are actually power cells with a built-in launching mechanism.
 * Previously, the Tonkor was able to launch teammates into the air, and could even move them around while they were channeling stasis-related abilities (Mesa's Peacemaker, Nyx's Absorb, etc.). This was removed to discourage griefing and exploits.
 * The Tonkor could also knock Hydroid out of Undertow and would damage a friendly Rhino's Iron Skin.

Bugs

 * Frequently, firing without zooming in will make the grenades explode right in front of the gun, causing the player to be launched.
 * The will have 30 rounds of Max Ammo instead of 40 when the Castanas or the Angstrum are equipped in the secondary-slot. This might be because they both draw from the same sniper ammo pool, and the above weapons have an ammo capacity of 30. The same can occur with the Talons, which have Max ammo of 20, thus resetting the Tonkor's Max ammo to 20.
