Thunderbolt

Bow explosion mod

Released May 3, 2013

Thunderbolt adds a chance for a bow shot to explode, reaching 30% at maximum rank. Consider it for a bow setup where this chance-based effect is useful, while accounting for its mod capacity and the explicitly listed Mending Shot exclusion.

Thunderbolt GUIDE

Understand Thunderbolt

Useful when…

  • Use on a compatible bow when you want the listed chance to explode.

What effect does it add?

Thunderbolt is a standard Bow mod. It gives a 7.5% chance to explode at rank 0, 22.5% at rank 2, and 30% at rank 3. The supplied effect does not specify explosion damage or other behavior, so the chance should not be read as a guaranteed explosion or a stated damage increase.

How should you account for rank and slot?

It has Madurai polarity, base drain 6, and a maximum rank of 3. Fusion costs rise from 30 Endo and 1,449 Credits for the first rank step to 120 Endo and 5,796 Credits for the final step. Rank it according to how much additional listed explosion chance is worth the capacity and resources in your build. It is incompatible with Mending Shot.

What alternatives do different jobs?

Arrow Mutation is an Exilus bow mod that converts secondary ammo pickups to 50% of ammo pickup; it addresses ammunition rather than explosions. Feathered Arrows and Plan B are Conclave-variant mods with different stated effects, so they should not be treated as ordinary standard-version substitutes.

Limitations and tradeoffs

  • Explosion chance is probabilistic and does not specify explosion damage in the supplied effect.
  • Base drain is 6; ranking requires increasing Endo and Credits.
  • Cannot be equipped with Mending Shot.

Common mistakes to avoid

  • Do not assume every shot explodes at maximum rank; the listed chance is 30%.
  • Do not equip it alongside Mending Shot, which is explicitly incompatible.
