Entropy Spike

Bolto explosive chance mod

Released Oct 24, 2014

Entropy Spike gives the Bolto a chance to explode and adds Entropy. Consider it only if the chance-based explosion suits your setup; the description explicitly says to use it with caution and does not specify what the explosion does.

Entropy Spike GUIDE

Understand Entropy Spike

Useful when…

  • Add the listed explosion chance to a Bolto.
  • Add Entropy while accepting the mod’s cautionary note.

Effect and equipment

At rank 0, Entropy Spike grants +5% Chance to Explode and +0.3 Entropy. At rank 2 the values are +15% and +0.8, and at maximum rank they are +20% and +1. It is a standard Bolto mod with Naramon polarity and base drain 4. The effect is explicitly marked “Use with Caution”; the supplied description does not establish the explosion’s damage, radius, or trigger details.

Rank investment

The three listed rank-ups cost 30 Endo and 1,449 Credits, then 60 Endo and 2,898 Credits, then 120 Endo and 5,796 Credits. Ranks raise the chance and Entropy amount. Invest according to how much you want those listed values; do not assume the chance alone defines the explosion’s practical damage.

Use with care

Because the mod itself flags its explosion effect for caution and gives no further explanation of the explosion, treat the chance as a conditional effect rather than a guaranteed benefit on every shot. It is specific to the Bolto and occupies a standard slot.

Limitations and tradeoffs

  • The explosion is chance-based and explicitly carries a cautionary note.
  • Uses a standard Bolto slot with base drain 4.

Common mistakes to avoid

  • Treating the +20% chance as a guaranteed explosion.
  • Assuming an explosion radius or damage value that is not specified.
