Tonkor

The Tonkor is a Grineer grenade launcher which fires concussion explosives. While its magazine is small, the Tonkor boasts very high critical rate and damage.

Characteristics
This weapon deals primarily damage.

Advantages:
 * Innate damage - effective against Machinery and Fossilized.
 * Physical contact with grenades deal damage.
 * High critical chance.
 * High critical damage multiplier.
 * Grenades have a blast radius of 5 meters.
 * Pinpoint accuracy.
 * Can use the launcher-exclusive mods and.
 * Holding down the fire button will display the next grenade's trajectory.

Disadvantages:
 * Innate damage – less effective against Ferrite Armor.
 * Explosion damage cannot be increased by, or  damage mods.
 * Grenades have travel time and heavy arcing.
 * Explosions can cause self-damage.
 * Grenades will instantly explode on hitting enemies, teammates or companions, potentially having lethal results.
 * Grenades that hit any surface have a high bouncing capability which makes it hard to stack on a desired spot.
 * This can be countered with the mod which will make the grenades stick to any surface.
 * Extremely small magazine size of just 2 rounds; requires frequent reloading.
 * Draws from the rare sniper ammo pool.

Tips

 * Projectile Speed modifiers like Zephyr's or  will help increase its launch speed significantly. Trajectory guide when zoomed will adjust with increased flight speed.
 * If the projectile speed is high enough, the grenade will explode on impact with any surface. The formula is the following:
 * Flight Speed (with 100% Ability Strengh) = Jet Stream + Terminal Velocity = 160%
 * Flight Speed = Jet Stream + 160% Ability Strengh= 160%
 * Flight Speed (with 40% Ability Strengh at least) = Jet Stream + Terminal Velocity + Riven Mod
 * It is possible to make a Tonkor build on Zephyr without increasing Ability Strengh, however, if Ability Strengh is less than 100%, then Projectile Speed is also affected since linked to Jet Stream . Also, the formula requires always Jet Stream since Tonkor riven disposition is only 1/5, which would give only 60% Flight Speed; so a riven combined with Terminal Velocity could reach only 120% Flight Speed instead of the required 160%. In conclusion, a riven mod with Flight Speed on Tonkor can be used as substitute of Terminal Velocity, or if Ability Strenght is less than 100% (in this case Terminal Velocity is still required).
 * It is encouraged to always add some margin on top of the required Ability Strength as gravity could slow down the grenade too much, preventing its explosion.
 * The Tonkor's self-damage property can be used to increase Vex Armor's buffs when using Chroma.
 * It is advised not to 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".
 * Previous design concepts show ("ALL").
 * 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.
