Multishot describes the number of pellets (bullets, projectiles, bolts, etc.) that Non-Continuous weapons will fire per attack. Continuous weapons are still affected by Multishot, by having the chance to increase the damage on the original damage instances. While multishot is a feature normally encountered mainly on shotguns, it can be added to any weapon through mods, effectively allowing you to fire more bullets without consuming extra ammunition on most weapons. Not only will this increase the weapon's damage, but each pellet generally has an independent chance to proc Status Effects and/or Critical Hits.
Most firearms in WARFRAME fire one pellet per round of ammunition, which takes into account the weapon's critical hit chance and status chance upon firing, and cannot be modified upon impact with a surface or a target. Multishot mods essentially give the weapon a chance to spawn an additional pellet when fired, which can generate a critical hit or a status effect independent of the "main" pellet, but otherwise will behave identically to it, such as taking the effects of mods into account, the weapon's overall Accuracy, Elemental Damage, and the like.
While the additional pellets can be seen veering away from the main pellet, if the weapon has an Accuracy of 100% (such as the Dera), and thus no spread at all, the additional pellet will overlap the main pellet. This can be verified by equipping a mod that decreases accuracy such as Heavy Caliber.
When Multishot is added in Continuous weapons, it functions similarly to Critical Hits (but with a fixed 2.0x multiplier), becoming the chance the weapon will roll bonus damage in multiples of itself, per each tick. But in return, it will not spawn additional beams or additional ticks of damage. This means that having Multishot on these weapons will not increase the amount of Status Effect proc chances per ammo consumed, unlike in projectile or hitscan-based weaponry, potentially making Hammer Shot more effective overall than Vigilante Armaments in these cases. Critical Damage also benefits off of Multishot damage, as Crit is calculated after Multishot damage.
For example, the Amprex deals 22 base damage per tick. With Split Chamber, each tick will have a 90% chance of doubling the damage to 44. If Vigilante Armaments is also installed for a total of 150% Multishot, the Amprex will always deal 44 base damage with a 50% chance to deal 22 more damage, totaling 66. If any of these values Crit, the weapon's Critical Multiplier will also be factored in, at the end.
When it comes to shotguns (or select rifles and pistols) however, they fire multiple pellets per shot, and thus gain a bigger benefit from Multishot mods in the process. To balance this interaction out, the listed status chance in the Arsenal UI is effectively divided across each pellet. The Status Chance per pellet is calculated using the following equation;
Status Chance per Pellet = 1 − (1 − Status Chance)(1 ÷ Pellet Count)
- Status Chance refers to the status chance of the weapon listed in the Arsenal.
- Pellet Count refers to the amount of pellets fired per shot.
For example, the Boar Prime has a status chance of 30%, and a pellet count of 8. Thus the Boar Prime's status chance per pellet is actually ~4.36%. Adding Hell's Chamber increases the Boar Prime's status chance to ~54.4%, but will also increase the pellet count to 17.6, which still results in a ~4.36% status chance per pellet. In order to overcome this, the weapon's status chance must be increased to 100% before Multishot mods are taken into account. This guarantees that at least one of the weapon's pellets will proc a status effect upon hitting an enemy.
You can calculate a weapon's pellet count using the following equation;
Total Pellets = Weapon Pellet Count × (1 + Multishot Modifier)
- Weapon Pellet Count refers to the base number of pellets fired per weapon attack.
- Multishot Modifier refers to the total value of all related mods added together.
Should the total pellet count be a fraction, the fractional part will be a chance to fire one more pellet.
For example, a Hek with a base pellet count of 7 with Hell's Chamber will have the pellet count of 15.4. This means it will fire 15 pellets per shot with a 40% chance of firing a 16th pellet. Meanwhile, a Lex with 180% multishot will have a pellet count of 2.8. It will therefore fire 2 bullets with an 80% chance of a third bullet on that shot.
Note that the in-game UI will show the sum of all the pellets' damage, so actual damage may be lower on weapons with large spreads where some pellets may miss entirely.
In addition, Riven Mods with Sati or Can in their names will also grant bonuses to Multishot, but due to their randomized stats it possible to get a Riven Mod with negative Multishot instead. In that case, the negative Multishot gives the weapon a chance of firing a "dud" round that deals no damage, and based on the weapon's Disposition it's entirely possible to get a Riven Mod with -100% Multishot, making the weapon completely harmless.
This section contains tables showing how multishot affects weapons with innate Multishot (that is, they fire multiple projectiles per shot. For all other weapons, consult the above equation). For brevity's sake, each Multishot percentage column refers to fully-ranked, non-Riven mods that grant Multishot, arranged by increasing Multishot value, followed by a combination of fully-ranked mods, again arranged by increasing value where applicable.

The table below refers to Scattered Justice, a mod that also gives multishot but can only be installed on the Hek.
