Brain Storm is PvE and Conclave 
Grakata mod that briefly increases Ammo Efficiency on a headshot.
Stats[edit | edit source]
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 |
Acquisition[edit | edit source]
- 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
20.
Notes[edit | edit source]
- Can also be equipped on the 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 Wild Frenzy. However, ammunition will not be refunded if Brain Storm activates during the burst.
- Additional headshots will refresh Brain Storm's duration.
Bugs[edit | edit source]
- On the mod card in-game, at max rank, the duration is rounded up to 1 second. This is purely visual, however.
Patch History[edit | edit source]
- Conclave Mods Converted to PVE:
The following Conclave Mods have been converted/balanced to PvE Mods! If you already own these Mods they will automatically be available in your Arsenal. You can still obtain these Mods via Conclave, but will also be added to Nightwave Series 3: Glassmaker Cred Offerings.
- Brain Storm (Grakata): On Headshot: +100% Ammo Efficiency for 1s.
