Warframe reworks Riven mods and caps ammo efficiency on October 22

Digital Extremes is removing Riven disposition entirely and capping ammo efficiency at 75%, so a weapon consumes at most one round every four shots. All Rivens will be reset to new base values equivalent to a 1.2 disposition, and players will receive an inbox reward to offset build changes.

• Ammo efficiency capped at 75%, one round per four shots
• All Riven mods reset to base values equal to 1.2 disposition
• Changes arrive in the October 22 update
• Riven Splicers testers get double rewards
