How To Maximize Fusion Rifle Consistency - Illustrating Range, Aim Assist, and Bolt Magnetism

Introduction

Previously, I had shared some observations regarding fusion rifle damage falloff and bolt speed. Those posts were far from conclusive, however, and the jury is still out on what exactly the Range stat does for fusions. After reading an informative post by /u/SevenMillion5, this comment by /u/ch4_meleon_, and the Massive Breakdown of Range, Accuracy, Aim Assist, and Stability by /u/Mercules904, I became determined to explore the question further. Analysis thus far has usually involved wall tests and lacked the presence of an actual Guardian target. This time I set out to observe fusion rifles as they behave with a target in front of them.

In this analysis, I look at aim assist and bolt magnetism related to fusion rifle range. I also take a closer look at accuracy-enhancing perks like Hip Fire, Hot Swap, and Eye of the Storm as they relate to fusion rifles. This guide really contains no advice that hasn’t been stated elsewhere, but I hope to illustrate why we do the things that we do, and provide a clear picture for what to look for in a fusion rifle.

Examining the Fusion Rifle Reticle

Fusion Rifle Reticle Comparison

What exactly are we looking at here? As explained by /u/Mercules904, the reticle contains two components — the crosshairs, which indicate the error angle where bolts may randomly project, and the segmented aim assist circle within which bolts can magnetize towards a target. This reticle is visible within the Last Rites story mission. I didn’t learn about this trick until just recently, so I was excited to jump into it with fusion rifle accuracy in mind.

Here’s a simple graphic to help visualize what appears in the reticle. Imagine the error angle forming a cone that projects from the end of the barrel, and the aim assist circle projecting a cylinder until the aim assist falloff point. The reticle is a two-dimensional slice of these two elements at a certain, yet unknown distance. Very generally, the Range stat narrows the accuracy cone, and the Aim Assist stat increases the size of the aim assist circle. A fusion rifle is most effective where the accuracy cone is smaller than the aim assist circle.

Aim assist falloff appears to be governed by zoom magnification; Compare the aim assist falloff between these two fusion rifles, configured with and without Rangefinder. Aim assist appears to fall off around 40 meters for regular fusion rifles, and 45 meters with Rangefinder. This coincides with the range where ammo crate markers are visible in Crucible, and Patrol beacons are visible on Patrol.

For most weapons, when a round is fired, the error angle grows (bloom) and aim assist degrades until the error angle reaches maximum bloom and the aim assist circle completely disappears. Bloom resets between shots, eventually returning to initial accuracy. The same mechanics are in action for fusion rifles, but produce unique behavior.

Fusion Rifle Reticle Behavior

Fusion rifles fire 7 bolts across 7 frames. You may notice in the frame-by-frame above that the accuracy cone reaches maximum bloom immediately and only appears to reset after all bolts are fired. It resets very quickly, in just two frames. My educated guess is the accuracy cone as it appears one frame after the last bolt fires actually represents the accuracy of all bolts after the first. (That is, accuracy resets to this amount before the next bolt is fired, returning to maximum bloom again, which is what we see when the frame renders.) Aim assist does degrade over subsequent bolts, but never completely vanishes. This is because bolt magnetism is extremely important to making fusion rifles feel consistent; if bolts were purely random, fusion rifles would be frustratingly inconsistent outside close range. The key takeaways are that the first bolt is the most accurate, all 6 subsequent bolts are equally accurate, and the region where bolts can magnetize shrinks between the first and the last bolt.

So, with this mind, what do we look for in a reticle? We want our aim assist circle to be as large as possible, and our error angle to be equal in size to or smaller than the aim assist circle for the best consistency. This way, we can maximize the range of consistency and be sure that bolts will magnetize regardless of error angle so long as we stay on target within that range. Unsurprisingly, many popular fusion rifles like Saladin’s Vigil, Plan C, and Stellar Vestige meet this standard.

Accuracy Perks & Fusion Rifles

I examined Hip Fire, Hot Swap, Eye of the Storm, Rangefinder, Hammer Forged, and Icarus to see what effects they have on fusion rifle accuracy and magnetism. I owe a lot to /u/Mercules904, who already explained these perks in detail. Most of what’s below just restates those findings, but there are some points specific to fusion rifles.

Hip Fire appears to increase Stability. Since the Last Rites reticle only appears while ADS, it’s difficult to determine what effects Hip Fire has on the accuracy cone or aim assist circle. Quick observations indicate Hip Fire does not appear to affect the aim assist circle.

Hot Swap increases bloom decay rate. Because bloom decays so quickly on fusion rifles, Hot Swap essentially guarantees that all 7 bolts fire with initial accuracy. Hot Swap does not appear to affect initial accuracy or aim assist.

Eye of the Storm improves the initial accuracy cone by an apparent 27%. Eye of the Storm triggers when shields fall below 50% and scales linearly as shield health decreases, reaching maximum effectiveness once your shields are gone. Eye of the Storm doesn’t affect bloom decay rate, but since the initial accuracy cone is that much tighter, bloom resets immediately between bolts. In this sense, Eye of the Storm effectively grants the benefits of Hot Swap while active. Eye of the Storm is by far the most powerful accuracy-enhancing perk, but requires you to be wounded. It’s probably best paired with a fast-charging fusion rifle that would be used in panic situations and would benefit most from additional consistency.

Rangefinder shrinks the entire reticle by 10%, which matches the zoom magnification factor bonus of 1.1x that Rangefinder provides. In addition, it increases the visual size of your target (effectively increasing the aim assist circle relative to the target), and reduces relative recoil. Since Rangefinder provides a percentage reduction to the error angle, it provides greater benefits to low-Range fusions. A Thesan FR4 with Hand-Laid Stock and Rangefinder (28 Range) has the same apparent error angle as a Panta Rhei with Rangefinder and Rifled Barrel (56 Range). Note that this isn’t the same as a direct boost to Range, so magnetism would break down for the Thesan much earlier than the Panta Rhei. Interestingly, Rangefinder’s effect on the reticle only takes place while grounded. Rangefinder also slows ADS time by 25%. If you intend to use a fusion rifle at close range, the additional zoom and slower handling from Rangefinder may actually prove harmful in practice despite the on-paper benefits.

Hammer Forged provides additional Range but does not affect initial accuracy any further than the Range boost it provides. It also has no effect on bloom decay rate. I determined this by comparing the accuracy cones of Plan C with Field Choke and Hammer Forged, and Branded Lord with Linear Compensator and Rifled Barrel. Both weapons have a Range stat of 65, and both have the same accuracy cone before and after firing.

Underdog increases the Range stat by 5 on fusion rifles. Underdog can’t push fusion rifle Range beyond the cap of 70.

Icarus reduces the airborne accuracy penalty by 75% and provides ~48% of original aim assist while airborne. Without Icarus, the accuracy cone grows by factor of 2.95 (0.74 with Icarus), and the aim assist circle completely disappears. This means bolts fired airborne are subject to extreme randomness and zero magnetism. I also compared the Sunsinger’s Angel of Light perk and Icarus, and found that Angel of Light reduces the airborne accuracy penalty by 100% and provides the same 48% aim assist that Icarus does. Icarus doesn’t appear to provide any additional accuracy while Angel of Light is active.

Stats Summary

Just to recap, below is a description of how each weapon statistic contributes to fusion rifle accuracy. I’ve also listed examples of available fusion rifles that can excel with perks that boost the associated stat.

Range tightens the accuracy cone (decreases error angle), decreasing the area where bolts may randomly project and allowing bolts to magnetize at longer distances. High Range combined with high Aim Assist contributes to consistency.

Aim Assist widens the area in which bolts can magnetize, thus increasing the margin of error allowed in a player’s aim. Low Aim Assist can be compensated for with high Stability, high Recoil Direction, or player skill. Low-impact fusion rifles tend to have much higher Aim Assist than high-impact ones, since they depend on more bolts to magnetize.

Recoil Direction eliminates horizontal tendencies in recoil, making it more vertical. More vertical recoil is easier to counteract and minimizes randomness in the recoil pattern. High Recoil Direction can compensate for low Aim Assist or Stability. High Recoil Direction is especially desirable when using fusion rifles at extended distances.

Stability reduces the amount of recoil experienced from each bolt. High Stability can compensate for low Aim Assist or Recoil Direction, and reduces the amount you have to manually control the reticle. Stability cannot overcome low Range — even with perfect aim, bolts are still subject to error angle, and will fail to magnetize if the error angle is too large. Further on in this guide, you may notice that I recommend prioritizing Stability last after all other stats. The reason for this is that Stability is the only stat that can be 100% compensated for by player skill if recoil is completely vertical. The other stats govern random elements that can’t be compensated for no matter what, so priority should be given to minimize those elements. The reality, though, is that there are very few ways to boost Recoil Direction, and you may end up performing better with a high Stability fusion since it requires less manual effort in the heat of the moment. Fusion rifles with good Recoil Direction have a high performance ceiling, but Stability can raise the floor if you’re struggling.

Demonstrating Bolt Magnetism

Fusion Rifle Bolt Magnetism Comparison

Aim assist governs bolt magnetism; if a bolt and your target are both within the magic aim assist circle, they can form a lethal attraction. Otherwise, they’re subject to your fusion rifle’s error angle. Magnetism doesn’t guarantee that a bolt will hit, just that it’s heading in the right direction. It’s entirely possible for a magnetized bolt to miss and for a non-magnetized bolt to hit by chance. What magnetism does is lay the groundwork for consistency.

The above video demonstrates the difference in magnetism between two Saladin’s Vigils at a distance of 45 meters, one with Hand-Laid Stock and the other with Rangefinder and Rifled Barrel. This is well beyond conventional fusion rifle range, but helps demonstrate the difference between the two. I chose these two clips carefully from a much larger set. I selected clips with as equal aim as possible so any difference in magnetism can be attributed to Range rather than recoil or human error. These clips also represent best and worst-case scenarios; there were certainly instances where the low-Range fusion hit many bolts, and the high-Range fusion hit only a few. What matters is consistency. The high-Range fusion consistently placed many bolts and sometimes even killed, while the low-Range fusion’s ability to do the same was left largely to chance.

Here are some additional clips that demonstrate magnetism in the Crucible:
