This build is designed primarily for focus farming in Elite Sanctuary Onslaught (ESO), however it is competent enough for leveling weapons in ESO or powerleveling other players in regular Sanctuary Onslaught (SO). In these missions, this build fills a damage focused role, similar to Saryn. In terms of raw damage output and survivabilty, this build comes up somewhat short compared to the meta Saryn build, however unlike that Sarny build, Equinox works well regardless of team composition, and even synergises very well with Saryns armor stripping capabilities.

Build requirements

This build will require 2 forma (replace one Madurai with a Vasarin, add one naramon) with an additional 6 to cover weapons. As always, the build will function, at reduced effectiveness, with fewer forma invested. If farming Focus, it is important to remember to slot the appropriate Focus Lens on both the frame and all weapons for the greatest efficiency.



A duality of contrasting forces in a single entity, Equinox unleashes wrath like the onset of daybreak, or draws life to a close like dusk's approach.

This build almost exclusively relies on Equinoxes day-form 4. There are 2 parts to this ability, the first causes all enemies inside the abilities radius to take a small amount of slash damage, which can be useful locating enemies if you chose to forgo an enemy radar mod (not recommended). The second part however is much more important: enemies that die while inside the radius of Equinoxes 4 have 75% (un-modable) of their health added to a pool, when the ability is recast, all of the stored health is released and is distributed, somewhat evenly (it's worth noting that closer enemies will take more damage) as slash damage among all living enemies inside the ability radius. In this build, this ability is used to clear, or near clear the entire tile in ESO. The exact amount of damage you need to achieve this map-wipe depends on a number of factors; enemy faction, number of Corrosive projections on the team, presence/absence of a Saryn, the number of living enemies, distance to those enemies etc. However there are some rules of thumb that can help you find the sweet spot:

  • try to get to a central location in the tile before popping your 4 every time, not only will you be more likely to hit more enemies, but you will also have a more consistent number of and distance to them.
  • only rarely should you ever pop much faster than 8 seconds after your initial cast, since you must never have initial casts closer together than 10 seconds or you will be locked out of casting your 4 for 15 seconds *after* the recast of the second cast.
  • in general, the amount of damage you need is inversely proportional to the amount of armor in the faction, this sequence should generally help you determine that: Infested<Corpus<Corrupted<Grineer
  • try to see how many enemies are present the enemy radar on the minimap before and after you pop, if the number does not seem to have decreased, you need more damage next time, if there are no enemies left at all, consider popping a little earlier next time
  • the amount of damage you need will generally increase as you move later into the zones
  • zone 1 will usually be somewhere around 60000.
  • zone 8 can be over half a million with bad luck
  • at the end of the day, it's more of an art than a science, practice makes perfect!

With all that said, the moment to moment gameplay of this build isn't centered too heavily on Equinoxes 4, after all, it doesn't do anything at all without some dead enemies to store. The primary weapon that should be used in this build is the Atterax, it does very respectable damage in a very respectable area, gives enemies a small stagger when it hits them, it is pretty much the ideal weapon for this use case. The Supra Vandal is more of a utility weapon in this build: for infested zones, the energy leech eximus are particularly bad, so the combination of a higher range weapon to stay out of their auras and the energy regen from entropy burst help significantly in that regard, but either way infested generally give little affinity, so it's mostly there to force past those zones, but the high fire rate can be useful against nullifiers as well.


There are a number of changes that can be made to this build, but first, it is important to think about why some things are the way that they are in the default. The most obvious standout to most people is probably rolling guard, it is not a very commonly used mod, but it is here for a very specific reason: to cover 4 casts in higher zones. In later zones, enemy damage scales very high, however, with this build, there are many stuns that effect enemies, Equinox's 4 stuns enemies when it first effects them with the slash proc, the atterax stuns enemies when it hits them, in general, you should receive relatively little damage most of the time when playing this build, except during the cast animation of your 4. There are a number of other solutions to this problem: adaptation and natural talent come to mind, in addition to just casting behind cover. In general, casting behind cover sounds like the ideal solution, but with the tight timing sometimes required for optimal damage output, that is just another thing to think about, and depending on tile and enemy spawns it may not be an option at all. Regarding adaptation and natural talent, most things that can kill you during the normal animation can still kill you in the sped up version, and Equinox has very little health to work with to build up that adaptation resistance, and with all the stuns, occasionally has problems maintaining stacks. With all that said, you may find more success with any of those options, or even something else.

In terms of weapons, there aren't really many good replacements for the Supra vandal, perhaps the Synoid Gammacor, but the author does not have that yet so it's hard to say. Parts of its functionality can be covered by any of the rakta weapons and all synoid weapons other than the heliocor, while the range/fire rate part can be covered by any number of weapons: any of the good automatic rifles, amprex, ignis wraith etc. For primary damage weapons, any spin-2-win melee with decent range will work, including any number of polearms and whips, Dokrahm zaws and the like, some regular melees will work to an extent, the author has had some success with fast Dokrahm zaws with exodia hunt, but it is worth pointing out that the hitstun from the Atterax is more important than you might expect. Outside of Melees, the Staticor is a decent choice, though not quite so since the range nerf, and there may be some merit to the Ignis wraith or Amprex, but, again, the author must admit they are undertested due to a lack of an adequate Supra Vandal replacement


Stepping into a Nullifier bubble, map resets (jumping into a bottomless pit etc.), and running out of energy will all deactivate Equinoxes 4 without dealing the stored damage, the stored damage will be lost and the ability must be recast, therefore it is strongly recommended to avoid these situations or recast early, even if very little damage is stored, if the situation is unavoidable.

Additionally, the recast explosion will not target enemies inside Nullifier bubbles and neither will their deaths be added to the health pool. Killing nullifers, or at least destroying their bubbles, should be a high priority.
