Patch History[]
Update 36.0 (2024-06-18)
- Trading Legendary Arcanes now requires you to be Mastery Rank 11.
- It’s important to note that only the player trading requires MR 11 and not the receiver.
- We needed to address an issue with exploitative Legendary Arcanes farming and ban-evasion account creation used to trade Legendary Arcanes. Other options we experimented with had the risk of innocent players getting caught in the crossfire of the ban-evasion subjects. When we took a look at Trading stats we found that a very small number of players below Mastery Rank 10 trade Legendary Arcanes, and therefore decided to go this route. This is purely a means of deterring the bad actors and ensuring legitimate trading for players.
- It’s important to note that only the player trading requires MR 11 and not the receiver.

- Introduced.

660 armor means a bonus +3.2x EHP multiplier.
So if you have at base 1000 HP and 300 armor, you have 2000 base EHP. With Arcane Reaper you have 960 armor which is a 4.2x EHP multiplier giving a total EHP of 4200, or +2200.
If you took Guardian instead, you would have 5000 EHP; +3000
The +24/s heal at 960 armor means you are healing 100.8 EHP/s, so if this is your only source of healing then it gives you more total health than Guardian after healing for only 8 seconds.
If, however, you have some other more powerful form of healing (like Tharros Strike), Guardian is better.
If you combine both at once, you would have a total of 1860 armor, and 7200 EHP!
It doesnt refresh anymore or is it just me?
It's refreshing fine for me.
On a low armor frame using melee this arcane offers 660 armor that refreshes with every kill. The constant effective health from that armor via damage reduction is worth having on a frame that otherwise has little armor. The health regen is the cherry on top of this arcane if you want survivability on a melee build. Pure heath regen is nice but at higher levels the dmage you are taking outstrips the health regen and you will want the armor for DR.
It's pretty incredible on Citrine since she has a decent health pool and her passive doubles the health regen, while the added armor gives a pretty meaty EHP increase whether or not you equip her with armor mods. Follow that with adaptation and her 2 and I don't even know what level enemies need to be to have more DPS than the regen effects can handle.
Done lvl 2000 with citrine SP circuit and survived even without this arcane, she is the beast.
There is a lot of discourse regarding the healthtanking value of this arcane VS grace guardian. The correct answer is that it depends on your warframe build.
A full umbral Inaros with 5 blue shards will benefit a lot more from grace due to the %percentage based healing, whereas a full umbral excal with damage shards would be better off with reaper, due to his lower health pool, and the extra armour assists in keeping him alive (Gloom is still way better anyway, even with the umbra bug.)
Rhino would prefer guardian for higher armour values. Combat discipline can force proc grace guardian, so they can be synergised with nourish or avenger. If you aren't running a melee build then there's no need for reaper. Tenno, please use your heads.
This isn't bad on Inaros or Qorvex, granted you do need to focus on a melee build for it to work but still, not bad.
Doesn't seem to be proccing off of Whipclaw in Simulacrum. It might not work on pseudo-exalted.
Yea I tested it in mission and it doesn't work with whipclaw. I haven't tried it with other pseudo-exalted weapons.
Easy to proc tho only really useful for melee builds: getting both decent armor increase and decent health ticks makes it a worthy consideration for what is basically a survivability arcane. Kinda Obsoletes arcane grace and other health-bonus arcanes.
This is pretty garbage compared to Grace
Counterpoint: You don't have to get hit for it to activate like grace
The armor in addition to health is not garbage. melee only though
Any word on how this works with vex armor? Would it apply before or after the multiplier for that?
They'll just stack additively. Not worth using due to diminishing returns.
Reaper is a flat / absolute value that is applied after all %percentage-based buffs. This in and of itself does not necessarily mean diminishing returns; that's only the case when used with very high armour multipliers such as a 350% strength vex armour on full umbral chroma prime.
Armor doesn't have diminishing returns, this is a common misconception. Every 300 armor you gain increases your effective health by an amount equivalent to your listed health.
For example, if you have 1000 HP and:
0 armor, you have 1000 EHP.
If you have 300 armor you have 2000 EHP (50% damage reduction)
If you have 600 armor you have 3000 EHP (66% damage reduction)
If you have 900 armor you have 4000 EHP (75% damage reduction)
If you have 30,000 armor, you have 100,000 EHP (99% damage reduction)
There's never any diminishing returns in the equation, it is a linear bonus whether you are going from 0 to 100 armor or going from 900 to 1000 armor.
That is diminishing returns though, when you're looking at the percentage increase that you get. Going from 1000 EHP to 2000 EHP is 2x - that's huge! Going from 2000 EHP to 3000 EHP is 1.5x - decent. Going from 3000 EHP to 4000 EHP is 1.33x - ehh... The value is reduced the higher you go. Just the same as everything else, base damage mods, elemental mods, whatever. It's better to combine different sources to multiply bonuses together.
Anyone know if this affects ironskin?
Probably does. Haven't tested it, but I don't see why not.
If it gives you armor after a melee kill then why wouldn't it stack with Iron Skin? Like duh.
So, if i am reading that description correctly, the effect of this arcane works like a combined grace and guardian with the activation being melee kills instead of getting hit?
That's what I'm getting from it yeah
Duhhh?
Shouldn't compare it to Grace, because what makes it so good is the fact that its regeneration is percentage based, as opposed to flat value
Still, on excal umbra with ~1000hp, arcane grace gives ~60hp/s. I'd say 24hp/s + 660 armor is a reasonable tradeoff
Is this arcane even possible to drop? I did almost 30 solo sp solo runs oppening 3 portals and so far i got everything except that aracane, hell im even close to max shotgun vendetta i have 15 so far...
I got one at steel path portal
I've never seen these portals.
Is this arcane only obtainable by the two mentioned methods under Acquisition? I see some people are getting it in different ways also like maxing the sp circuit or idk if thats even possible...
Is this arcane's health regen added to the heal rate of Nidus's passive health regen, or does it replace/get replaced by whichever number is bigger?
What?... Why would one replace the other?... They work together.
Where does it read on the Arcane: "Arcane Reaper will replace the base health regen on Nidus and replace it with its own" at? You noobs ask the most dumbest questions.
Why would it specify that? The amount of things in this game that are not specified and you expect that interaction to be specified on this arcane for a particular warframe. Both of you are dumb.
The wiki would specify if reaper regen replaced nidus regen. They stack
Exalted Umbra Blade, with both Chromatic Blade and Furious Javelin, slaps, especially once you get your decrees going in Circuit.
I'm on it.
Now get nourish as helminth as well as archon continuity and make your exalted blade pure toxin via chromatic blade. From the very first hit you're already getting 3 guaranteed statuses, so condition overload goes brr
28 runs of SP duviri to max out these arcanes, assuming you're not picking up incarnons and other stuff along the way. Yikes. I wouldnt mind if Drifter gameplay wasnt.. what it is
But it is what it is so Im definitely gonna be buying these with plat. It certainly seems worth it
Should be easier to obtain when Kullervo's update comes out with the portals that guarantee an arcane drop.
Iirc, in the next update, the only guaranteed arcanes are non legendary ones, just like how it works in rank 11+ in circuit SP.
Welp looks like this is in the pool for the bonus portals. Only on steel path though.
28 runs, lol if you bought every one on timer, that would be so dumb and take forever. There's like 13 different duviri arcanes and if you only planned on buying from acrithis and checked daily - I don't even know if thats random or in sequence, but if they went in order that would take almost a year.
This arcane works out to +220% to your armor health multiplier found here. Vs it's main contender Guardian which is a +300% to your armor health multiplier. This works out to only +80% more health in Guardian's favor.
While Guardian may look better on paper, we also have to take into account what is needed to activate it. As many have pointed out Guardian requires for you to take damage first, and only at a 15% chance to activate. Reaper though is guarantied on a melee kill. However many forget to mention that Guardian is not refreshable, while Reaper is. That means after the 20s Guardian is up, you need to play the luck game again and hope it activates soon before you die. If you pick up Reaper you can keep it up 100% of the time. Even if you aren't a melee focused build you can keep a Glaive Prime ready to throw when you need the extra heals and armor.
I would say Reaper wins out in most situations due to it being refreshable, guaranteed activation, and also gives you healing which is boosted by the armor it grants. All of that for 10 less seconds and 80% less to your armor health multiplier.
Pointless on Valkyr since she's literally invincible.
Arcane Guardian just flat out sucks in regards to activation. There can be 30 enemies attacking you at once and that thing still wouldn't activate. I've been using it for about 3 months, and I'm totally dissatisfied with it.
Works fine on my machine. Almost 100% uptime.
This arcane is not worth slotting even if you're health tanking.
I hope they change this to work with pseudo exalted melee's like Whipclaw.
Does the buff from this overwrite itself or does it have to finish cooldown to reapply?
It will refresh, don't need to wait.
Just swapping 15% for 100% Proc is worth the 300 Armor when you're going into higher level missions where 3-4 hits can put you down. The shorter duration looks like a con but honestly getting a melee kill every 10s is a lot more forgiving than getting hit 3 times and hoping for good RNG...
Yeah, this displaces Guardian easily. Plus you get constant health reg on top of the armor. This and the new legendary bow arcane are the two I'm most interested in.
Honestly seems like a pretty good new Arcane. Depending on the frame, being gaining anywhere from 47% to 5% more damage reduction from the lowest to highest armor frames is pretty dang good, and with how DR and healing effectiveness works it's a pretty sick deal.
"Guardian is still better" you know that sometimes you gotta get out from your comfort zone, right? and you know that DE fucked up addressing "meta arcanes" by making them unable to refresh while the arcane takes effect, right? fuck you DE for boredom spear.
Receiving the bonus armor from your actions instead of from enemies dealing damage to you is a pretty significant durability buff compared to Guardian, especially when you're using armor arcanes to add some bulk to a flimsier frame instead of to the likes of Inaros and Grendel (yeah they'd probably prefer Guardian). Compare people sacrificing any benefit from their aura slot to actively damage themselves instead just to proc Arcane Avenger without eating enemy fire. Don't underestimate the strength of active control over our buff uptime.
Yeah, Guardian is still better on beefier frames that can easily take 3-6 hits to get guardian to proc without killing them/putting them near death.
But for squishy frames with low health where Grace isn't a viable option, this is probably up there with Aegis in terms of survivability arcanes for low health frames.
Arcane Guardian is Crap! You must be the most delusional player in the game if you believe Arcane Guardian is "better" than Arcane Reaper. That damn arcane rarely activates, and in most times when you really need it to activate, it doesn't. 15% chance always means 30-50 enemies can be attacking you at once and that damn thing still wouldn't activate. I've conducted rigorous testing on Arcane Guardian for over 3 months, and my results prove that its flat out unreliable.
How can it compete with Arcane Reaper where you gain 660 armor consistently on top of +24 healing rate per 10s that refreshes infinitely. Pair it with Healing Return for +35 healing and you're damn near unkillable in most steel path content. You players suck at assessment, and obviously suck at the game overall too if you believe Arcane Guardian is better than Arcane Reaper. Go take a nap.
