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 critical damage multiplier.
 * High AoE damage and decent blast radius of 5m.
 * 325 damage that can be increased by mods.
 * Decent fire rate for a grenade launcher type weapon.
 * Can use the exclusive Adhesive Blast and Firestorm mods.
 * 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 upwards.
 * 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
PS% >= 234 - FS%.
 * Projectile Speed or Flight Speed modifiers like Zephyr's Jet Stream or Terminal Velocity 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. In the case of a Jet Stream Zephyr, the minimum amount of Power Strength percentage (PS%) needed to achieve this effect given a particular percentage of Flight Speed (FS%) is given by the formula
 * It is encouraged to always add some margin on top of the required power 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 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".
 * 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.

Bugs

 * Frequently, firing without zooming in will make the grenades explode right in front of the gun, causing the player to be launched.
