The remotely triggered Castanas quietly deliver a lethal dose of electricity to unsuspecting enemies.

The Castanas are a throwing type secondary weapons with Electricity b Electricity detonation charge that can be detonated remotely by using the Alternate Fire, much like the Penta. Although lacking in throwing speed like other thrown weapons, they can be stacked up to six then detonated all at once to create a wide array of crowd controlling opportunities, thanks to their electrical explosion and chaining effects.

Weapon LoadoutsEdit


  • The normal animation and arc behaves similar to other thrown secondary weapons.
  • Castanas can stun-lock bosses such as Lech Kril.
  • Primary fire throws the Castanas, secondary fire detonates them.
  • Charges will stick to any surface (enemies, allies, companions, etc.); after sticking, they will proc Electricity b Electricity with 100% chance when detonated.
    • When thrown while running backwards, it is possible that they can stick to your Sentinel or your Frame itself.
    • This guaranteed Electricity b Electricity proc does not damage the user even if when dealing self-damage.
  • Throws that were made by the left hand are further from reticle by a few degrees to the bottom compared to the right hand.
  • Can not proc Radiation b Radiation on user.
  • When Magnum Force is added, the Castanas will begin to spread apart on throws if Multishot mods are applied. This may be helpful for combating the small blast radius they have by spacing them slightly apart from each other.
  • The Castanas are currently subject to a bug that dramatically increases projectile spread when using multishot mods. Equipping a low-rank Magnum Force will fix this.
  • Throwing these at an Arctic Eximus snowglobe and detonating them will kill the Eximus.
  • Castanas thrown by Mirage's illusions from Hall of Mirrors will not interfere with the maximum amount of armed Castanas at a given time.


  • Caution should be taken when this weapon possesses elemental damages such as Magnetic b Magnetic, Toxin b Toxin and Viral b Viral, as these would deliver their corresponding negative effects should the user be caught in the blast area.
  • As a Nyx, throwing several Castanas to the floor, casting Absorb on top of them and detonating them makes a good (and fast) combo for an instantly "charged" Absorb with the right build.
  • Mirage's Hall of Mirrors can be used to increase the number of Castanas that can be planted, but the holograms' Castanas will detonate a few seconds after impact; though they will not damage the player and can still also be detonated manually in the given time they are active.
  • If you are willing to take the damage, you can detonate the Castanas right on top of yourself by pressing the fire and secondary fire keys at the same time. This technique is useful for Link + Blessing Combo.
    • Note that as of Update 13.3, the Link + Blessing Combo is less effective, due to the fact that Blessing doesn't confer invulnerability any longer.


  • The Castanas are the first thrown secondary weapon that delivers Area of Effect damage.
  • The detonation feature is similar to that of the Penta grenade launcher, which also allowed users to detonate on command.
  • The word Castañas means "chestnuts" in Spanish and Greek, judging how the knives are thrown, then "open" themselves, revealing their explosive cores.
  • The Castanas are the first throwable weapon of its kind to be thrown in "Semi-auto".


  • Castanas thrown at the shield of a Nullifier Crewman or Corrupted Nullifier will bounce off and land in another location.
  • If Multishot is modded onto the Castanas in any way and happens to activate, the castanas thrown will travel in widely different directions, landing far away from the intended target.
