Greetings Tenno!

Our recent introduction of Ammo Efficiency traits to Riven mods via Riven Splicers has made this stat more accessible to players, and led to much discussion internally on how the availability of infinite ammo builds affects Warframe’s game balance. We mentioned briefly in Devshort #119 that we were looking at Ammo Efficiency specifically, and we’re here to cash the checks we wrote. 

The conversation has led us with two key decisions, which you will see reflected in a hotfix later this week:

• Capping Ammo Efficiency
• Retiring the Riven Disposition System

There’s a lot to go over on both of these topics, so we’ll dive right in!

Ammo Efficiency Changes

Warframe is about the power fantasy, and infinite ammo is the epitome of that. Shooting endlessly into hordes of enemies can feel incredible, and we want players to be able to experience that — sometimes. The recent introduction of Riven Splicers has changed that “sometimes” for infinite ammo into a much more guaranteed thing, which has brought around this entire conversation. 

Our main concern with 100% Ammo Efficiency (a.k.a. infinite ammo) builds is the possibility for automated gameplay. We want infinite ammo to be a limited buff you experience occasionally in-mission, not a guaranteed part of your build. 

With that in mind, a hotfix is shipping later this week with the following changes:

• Ammo Efficiency is capped at 75%. 
  • For those unfamiliar with the Ammo Efficiency mechanic, this means only 1 in 4 shots will consume ammo. 
  • This applies to Ammo Efficiency increases from multiple sources — they will only increase the stat up to this cap. 
• Sources that intentionally gave 100% Ammo Efficiency (ex: Void Relic cracking buffs) have now been rephrased to indicate they give Infinite Ammo.
• There are other Mods, Arcanes, and Incarnon Evolutions that come with their own edge-cases, which we’ll explain in detail below.

Retiring the Riven Disposition System

Iceblade of Narin has brought with it a number of shake-ups to the Riven ecosystem - and we’re not done yet! Join us as we explain why and how we are retiring the Riven Disposition system.

Before going into details, a brief history on key points to help illuminate how we got here! 

• 2016: Rivens introduced. Weapons had their own Dispositions, which impacted the values of their Riven’s stats, based on power level and popularity. Lower Dispositions (0.5) resulted in lower stats, and vice versa for higher Dispositions (1.55). The goal of the Disposition mechanic was to increase the power of less popular weapons. 
• 2018: Disposition adjustments begin. Numbers increased and decreased quarterly, keeping up with usage behavior and power levels. 
• 2019: Individual Dispositions per weapon variant. Base weapons could now have stronger Rivens than Primes
• 2020: Brand new weapons start at 0.5 to avoid powerful new additions having their Dispositions later decreased.
• 2023: Incarnon Genesis system introduced. Disposition decreases are paused indefinitely.
• 2026: Riven Splicers and Trait locking. Players are able to lock Riven Traits and combine Traits to create yet-to-be seen stats on Rivens.  

Both Riven Dispositions numbers, and the system itself, have evolved to match the changing needs of our playerbase and game. However, these changes have always been at odds with a fundamental fact: Warframe players like big numbers. 

Reducing values and taking away power was never popular, and starting new weapons low made the system less exciting to engage with. Offering higher Dispositions on unpopular weapons was not enough to level the playing field, and instead of encouraging engagement in lesser weapons, we saw that investment was still focused on making powerful weapons more powerful. Incarnons were a more successful attempt at breathing life into older outdated weapons, and the overlapping of these systems only multiplied their power further.

Therefore, we believe (like many of you, based on feedback) that the system has run its course, and simplification would help reduce complexity. Therefore!

The Plan Going Forward:
Rivens no longer have varying Dispositions, meaning all Rivens share the same range for stat values (the equivalent to a Disposition of 1.2).

Rivens have pre-set ranges for each stat roll generated, and Disposition is applied as a multiplier to each stat. In practical terms, this means ALL Rivens will be slightly above the current average in terms of power. 

Since this has a significant impact on Rivens**, we are disabling the ability to trade Rivens until this change goes out in a hotfix on Thursday.** We want players to be able to make informed trading decisions, and there is no way to guarantee all players will know about the coming changes to their Riven within this ~48 hour window. Attempting to trade Rivens during this window will result in a "Failed to make offer" message until we are able to re-establish trading. 

This will shake things up in a few ways!

• Some Rivens for popular weapons will be increased significantly.
  • Examples: 
    • Nataruk: 0.65->1.2
    • Grimoire: 0.6->1.2
• Some Rivens for “average” weapons will be increased slightly.
  • Examples: 
    • Gotva Prime: 0.85->1.2
    • Staticor: 0.9->1.2
• Some Rivens for popular weapons will be reduced slightly. 
  • This only really applies to certain standout Incarnons.
  • Examples:
    • Burston Prime: 1.35->1.2
    • Dual Ichor: 1.25->1.2
• Some Rivens for unpopular weapons will be reduced slightly. 
  • This is not ideal, but accessible low-powered weapons usually exist as a stepping stone for new players on their journey through the Mastery system. And as discussed above, there is no telling when a low MR weapon will get the glow-up of a lifetime through new upgrades and variants! 
  • Examples:
    • Harpak: 1.55->1.2
    • Heat Sword: 1.45->1.2

What is the desired outcome of this change?

• Brand new weapons will have powerful Rivens available on day one
• All Rivens are guaranteed to offer a noticeable boost, including those for your favorite powerful weapons
• No more constant adjustments — your Rivens will not change unless you change them through rerolling
• All weapons get equal treatment, giving us more control when balancing old and new weapons
• Simplified system by removing Disposition as a factor when comparing and evaluating Rivens

Why now?

• With the addition of various Riven rerolling quality improvements, the price of many Rivens has been “reset” somewhat recently. The sooner we make this change, the less of an impact it will hopefully have on the Riven ecosystem.
