Thunderbolt is a mod that gives arrows fired from primary bows a chance of exploding on impact of a surface or an enemy.


Rank Proc Chance Cost

3 +30% 9


  • The explosion deals 250 DmgBlastSmall64.png Blast damage to the target, as well as to nearby enemies within 10 meters of the blast.
    • The explosion inflicts self-stagger.
    • Unlike the area blasts of dedicated blast weapons like Launchers, Thunderbolt does NOT have a safety distance to prevent self-stagger. Furthermore, if the shot hits and explodes close enough to you it will do a full Knockdown instead of just a self-stagger.
    • The explosive damage from this mod cannot be increased with base damage, such as Mod TT 20px.png Serration, and elemental mods such as Mod TT 20px.png Hellfire, but it will be increased by Bane mods, like Mod TT 20px.png Bane of Infested.
  • Compared to Launchers, the Thunderbolt blast has full Punch Through (like most Launchers) and zero falloff throughout its entire area of effect (unlike most Launchers), so all enemies take full damage even at the outer-most edges of the blast while behind cover.
  • The blast area is increased by Mod TT 20px.png Firestorm or Mod TT 20px.png Primed Firestorm.
  • The explosions are silent.
  • Arrows fired at terrain and other surfaces still explode, but not arrows fired at teammates or other allies.
  • When the explosion occurs, the projectile of the arrow causing that is actually "dissolved". Thus any subsequent mechanics relating to the projectile will not happen, such as punching through or the spore coming after the arrow of MutalistCernos.png Mutalist Cernos.


  • As the blast damage is not improved by damage increasing/elemental mods on the corresponding bow but it IS reduced by the resistances/armor of the enemies, viable builds using Thunderbolt rely on sending out a massive number of arrows quickly to have as many explosions as possible.
  • Pair with a high-rank Multishot mod for maximum effect. Calculating per shot, there will be a 48.9% chance of at least one explosion with both Mod TT 20px.png Split Chamber and Thunderbolt at max rank. The chance for two explosions is 8.1%. With Split Chamber, Mod TT 20px.png Vigilante Armaments, and Thunderbolt there is a 58.4% chance of at least one explosion, a 15.3% chance of at least two explosions, and a 1.4% chance of three explosions.
  • When facing groups of enemies at medium-to-long range, maximize splash damage by aiming for a nearby surface rather than directly at an enemy.
  • Since explosive damage is unaffected by the amount of time the shot has been charged, rapid shots can be more effective at quickly taking out large groups of enemies.
  • This mod pairs well with the Attica.png Attica or Zhuge.png Zhuge due to the high volume of fire of crossbow-type primaries compared to other bows, ensuring a very high chance of bolts exploding within a short period of time. Combined with the higher ammo capacity, using Thunderbolt on these weapons is very effective for dealing with crowds.
    • Combining the Attica or Zhuge, especially modded for fire rate, with MirageIcon272.png Mirage while using her HallOfMirrors130xDark.png Hall Of Mirrors ability can create an extremely large number of explosions over a wide area, since arrows fired by Mirage's clones can also proc Thunderbolt.
      • The ZhugePrime.png Zhuge Prime does not benefit from this mod, as the arrows already have a guaranteed explosion after making contact.


Patch History[]

Update 30.8 (2021-10-04)

  • The explosion FX for Thunderbolt have been updated.

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

Update 18.10 (2016-04-29)

  • Improved the FX and performance of the Thunderbolt mod.
  • Reduced the FX of the Thunderbolt mod on Mirage's clones to improve performance.

Hotfix 14.2.1 (2014-08-14)

  • Improved performance of Thunderbolt explosions on low end systems.

Update 9.8 (2013-09-03)
