Napalm Grenades is a Weapon Augment Mod for Penta.png Penta, SecuraPenta.png Secura Penta, and CarminePenta.png Carmine Penta that causes the grenades to leave a burning patch on the ground upon impact. The weapon also gains increased status chance, and its damage type is changed to purely DmgFireSmall64.png Heat and overall damage increased by ~73%.

Napalm Grenades could be obtained by reaching Rank 22 with Nightwave during Series 1 and Rank 13 during Intermission II.


  • Overall damage will increase, though two parts of the damage still remain. As an example, an unmodified SecuraPenta.png Secura Penta equipped with nothing but Napalm Grenades will deal 325 DmgFireSmall64.png Heat area of effect damage, as well as 325 DmgFireSmall64.png Heat direct impact damage. If either procs, the enemy will be dealt procs equal to 162 DmgFireSmall64.png Heat damage.
    • In addition, direct impacts will create a separate 100 DmgFireSmall64.png Heat which procs, likely there only to guarantee that enemies hit directly will be set on fire.
  • Cannot be used with Mod TT 20px.png Tether Grenades.
  • The fire patches generated by this mod last about 5 seconds.
  • When installed, Penta's grenades are changed to detonate on contact while still maintaining the manual detonation function with Alternate Fire allowing mid-air detonation and possible headshots on humanoid targets, also resulting in fire patches spawning mid-air.
    • Mod TT 20px.png Adhesive Blast can be installed to prevent grenades from detonating on contact by making them stick to the object that they make contact with in which they can be manually detonated or will auto-detonate about 5 seconds after attachment.
  • Unlike similar weapons such as Torid.png Torid, Pox.png Pox, MutalistCernos.png Mutalist Cernos and Ogris.png Ogris with Mod TT 20px.png Nightwatch Napalm, the fire patches generated by this mod do not deal direct damage, but instead proc DmgFireSmall64.png Heat status effect when enemies enter the effect radius. This deals very little damage regardless of the mods on the weapon, but causes enemies to flail around. This effect works on the player as well. The Heat status effect is not affected by status duration mods.
  • Similar to most (or all) mods that increase base status chance, other mods that build off status will still go off of the weapons original base status, not the new status created by Napalm Grenades.
  • When used with MirageIcon272.png Mirage's HallOfMirrors130xDark.png Hall Of Mirrors, it will create extra patches of fire.
    • The fire-patch of the user will cause DmgFireSmall64.png Heat damage while the clone's fire-patches are only visual and will not damage anything.
  • Unlike Mod TT 20px.png Nightwatch Napalm, the small fire patches range cannot be increased further, restricting the crowd control benefits of the bonus DmgFireSmall64.png Heat.
  • When modded to create DmgGasSmall64.png Gas or DmgRadiationSmall64.png Radiation, direct hits and the patches will still deal DmgFireSmall64.png Heat damage and status effects, though this is just for utility or crowd control as they will deal very low damage.


Napalm Grenades Projectile. Strangely Grineer Themed.


  • Napalm Grenades changes the appearance of each individual grenade to a Grineer-like device, as opposed to the stick-shaped charges the Penta normally fires. These resemble the molotov-like grenades that Saturn Six Fugitives throw, making the same glass-shattering sound effect on impact and leaving the same yellowish-orange "stain" on the surface they explode against in addition to the fire.
    • These effects are also shared with the Thermia Canisters used when fighting Exploiter Orb.
  • The fire patch left behind is similar to the function of the old Mod TT 20px.png Nightwatch Napalm mod for the Ogris.png Ogris, before it was changed to a large fireball in the air instead of fire patches.
