Brain Storm is PvE and Conclave GrineerAssaultRifle Grakata mod that briefly increases Ammo Efficiency on a headshot.

StatsEdit

The duration value in the in-game description is rounded to the nearest integer and is inaccurate as a result.

Rank Ammo Efficiency Duration Cost
0 +25% 0.125s 10
1 +50% 0.25s 11
2 +75% 0.375s 12
3 +100% 0.5s 13

AcquisitionEdit

  • This augment may be rewarded after a Conclave match, regardless if the player wins or loses the match in question.
  • Beginning in Series 3, this augment can be purchased as a Nightwave Cred Offering for CrystalCred6420.

NotesEdit

  • Can also be equipped on the PrismaGrakata Prisma Grakata.
  • Ammo Efficiency means the Grakata will not consume ammunition when firing; at full rank, the Grakata will not consume ammunition at all if you reliably score headshots and keep the buff going.
  • Can be used with Mod TT 20pxWild Frenzy. However, ammunition will not be refunded if Brain Storm activates during the burst.
  • Additional headshots will refresh Brain Storm's duration.

BugsEdit

  • On the mod card in-game, at max rank, the duration is rounded up to 1 second. This is purely visual, however.
