Acquisition

• Available for  20x Cred creds from the Nightwave Cred Offerings store on a rotational basis.

Notes

• As stated on the mod description Rifle Amp increases rifle damage, but it also affects bows, sniper rifles and launchers ( Ogris,  Penta, etc.). Shotguns do not benefit from this mod,  as it has its own aura counterpart.
• Rifle Amp adds to the base damage as  Serration and  Heavy Caliber do.
  • Rifle Damage = Base Damage × (1 + Serration + Heavy Caliber + Rifle Amp)
  • Therefore, the actual bonus from a maxed rifle amp is only +(27 ÷ (1 + Damage Bonus ))%, where Damage Bonus is the damage bonus from Serration and Heavy Caliber as a decimal fraction. That's +12.3% for a 7/10 Serration, +10.2% for a maxed Serration, and +6.3% for a maxed Serration and maxed Heavy Caliber.
  • Assuming a maxed Serration and no Heavy Caliber is equipped on the rifle, without damage type modifiers, against an armored enemy, it will deal more damage with  Corrosive Projection than with Rifle Amp if the target's armor is higher than 134. For a damage type that has a +75% bonus against the target's armor type, Corrosive Projection surpasses Rifle Amp if armor is higher than 536.
• Can be stacked with other members using this aura, for a total of +108% additive damage bonus.

Patch History

Update 19.13 (2017-03-09)

• Rifle Amp and Shotgun Amp Auras now apply to Titania's Dex Pixia weapons.

Hotfix: The Silver Grove 3 (2016-08-23)

• Buffed the Shotgun Amp Aura Mod to feel more comparable to Rifle Amp. It is now 18% at Max Rank.

Hotfix 9.1.1 (2013-07-15)

• Fix for  Rifle Amp Aura stacking. A word from the designer: Rifle Amp, 45% damage buff stacking was too much, reduced to 27% (4.5% base). This was a typo on my part.
