Arcane Enhancement
Tradeable
Information
Type	Crafted

Arcane Enhancements are special items that can be installed on certain equipment to grant them buffs that can be activated by achieving certain conditions within a mission. There are several major types of Arcanes that can be applied to their own dedicated set of items. Arcanes can be freely installed and will not be destroyed if they're unequipped or replaced by other Arcanes.

Arcane rarity is indicated by the color and design complexity of the Arcane. Common Arcanes are Bronze, Uncommon are Silver, Rare are Gold, and Legendary are Platinum. The higher ranks are denoted by the higher number of connectors on the bottom and the higher number of chevrons on the top of their individual icons.

Mechanics

Arcanes are activated by accomplishing its trigger condition (e.g. landing a Critical Hit, or taking damage, etc.), which will then have a percentage chance to activate the stated effect. If an Arcane's effect has a limited duration, the duration can be renewed by triggering it again. 

Application

Arcane upgrade interface.

A total of two Arcanes can be equipped on each Warframe and Operator (when an Arcane Helmet is used only a single Arcane can be equipped alongside). A maximum of one Arcane can be equipped on Zaws, Kitguns, and Operator Amps, however. They can be installed through their respective upgrade screens for the item. Arcanes can be upgraded via the Arcane button at the bottom of the Foundry or while equipping one. Rank insignia of an Arcane will be visible below its name, denoting how many upgrades it has undergone. Much like Mods, Arcanes can be equipped across multiple items, though they have a unique progress bar of their own to the right of the Foundry selection. Similarly, duplicate Arcanes cannot be equipped on the same item.

Rank

An Arcane can be ranked up by sacrificing duplicate unranked Arcanes of the same type, increasing their effects. This can be done inside the Orbiter:
ESC  > EQUIPMENT > FOUNDRY > ARCANES
Every successive rank-up requires one more Arcane than the previous one. The maximum rank of an Arcane depends on its type:

Arcanes required:	Rank 0	Rank 1	Rank 2	Rank 3	Rank 4	Rank 5
	All Types (incl. Virtuos, Exodia & Pax)				Warframe & Magus
- in Total	1	3	6	10	15	21
- for next Rank	-	+2	+3	+4	+5	+6

Warframe Arcanes

Arcane Drop Model

Warframe Arcanes can be obtained by either killing or capturing Eidolon Teralysts, Gantulysts, and Hydrolysts, though capturing will yield more exquisite rewards than simply killing them. For example, if a Teralyst is simply killed, it will only yield common Arcanes, but capturing it will yield a higher chance to drop the more uncommon ones.

Update 27.3 (2020-03-24) added all Eidolon Arcanes in Operation: Scarlet Spear, purchasable from Little Duck using Scarlet Credits for the duration of the event. In Update 29.6 (2020-12-18), the Arcanes returned through Operation: Orphix Venom, purchasable from Father using Phasic Cells for the duration of the event. Update 29.10 (2021-03-19) permanently added the Orphix mission to the game, with all the Arcanes available through Rotation C.

Hotfix 25.7.6 (2019-09-18) introduced 5 additional Warframe Arcanes, which can be obtained from Arbitrations.

Update 29.5 (2020-11-19) introduced 3 additional Warframe Arcanes, which can be obtained from Arcana Isolation Vaults.

Notes

• The benefits of Arcane Enhancements carry over to the Archwing mode of gameplay if players have an Arcane Enhanced item equipped on their active loadout's Warframe. (Requires more testing!)
  • This seems not to be true for some cases, such as Arcane Nullifier on the plains. It will not block Magnetic procs from water when in Archwing, but will on foot.
• The amount of Arcanes $A$ required for rank $n$ follows the sequence of triangular numbers given by: $A = \frac{(n+1)(n+2)}{2}$
• Before Update 24.6 (2019-04-04), Magus, Virtuos and Exodia Arcanes in Cetus are purchasable as blueprints, requiring time and resources to build in addition to standing.
  • Built Arcanes can be traded between players, however Arcane blueprints cannot.
• Because they are dropped as mystery items in the form of a Mod item, Arcanes dropped by Acolytes in steel path will be sucked up and permanently destroyed by Scavenger Drones. The steel essence will be picked up, but will be dropped on death however.

Patch History

Update 30.5 (2021-07-06)

MELEE / PRIMARY BALANCE CHANGES

Primary and Secondary Weapon Arcanes

We are going to start with the biggest change: You can now add Arcane Slots (name not final) to your Primary and Secondary weapons, and fill the Slots with new Arcanes that enhance and reward diverse gameplay.

Our entire approach to making Guns a comparable choice in your Arsenal orbits around the notion that Gunplay is fundamentally more varied than Melee: there are pinpoint accuracy guns, AOE guns, and high fire rate Guns (and everything in between). There’s reload times, magazine sizes, and more. We want to make these varied options better at what they do by rewarding you for using them well - thus, Arcanes!

Because the Gunplay falloff is more of a late-game problem, these new Upgrades will be earned through late-game content systems -- namely, the Steel Path. You’ll be able to get the Arcane Slot Unlockers from Steel Path Honors, whereas the Arcanes themselves drop from Acolytes in the Steel Path! The spawn frequency of Acolytes is also being increased, meaning you’ll get more Steel Essence, as well as more chances for the Arcane you want. All Acolytes will drop them!  

There are 6 Arcanes (3 Primary, 3 Secondary) that you’ll be able to rank up and put to put into the new Slots:

PRIMARY:

The first Primary Arcane is designed with Primary weapons that perform well as AOE or high rate-of-fire weapons. This Arcane will reward kills with the following stats at Max rank:

PRIMARY MERCILESS
On Kill:
+30% Damage for 4s. Stacks up to 12x.
+30% Reload Speed
+100% Ammo Max

The more you kill, the more damage you can build up. Groovy!

The second Primary Arcane is designed with high precision weapons in mind. Make your Headshots count for greater performance (excluding AOE headshots)!:

PRIMARY DEADHEAD
On Headshot Kill:
120% Damage for 24s. Stacks up to 3x.
+30% to Headshot Multiplier.
-50% Weapon Recoil

The final Primary Arcane is designed with using your full loadout in mind, enter Melee synergy:

PRIMARY DEXTERITY
On Melee Kill:
+60% Damage for 20s. Stacks up to 6x.
+60% Holster Speed.
+7.5s Combo Duration.

SECONDARY:

Secondary Weapons will receive the same options as Primary Weapons for their Arcanes, but with their own version. In practice, you’d be able to equip yourself with a Precision Secondary like the Knell, a high-fire rate Primary like the Grakata, and select the Arcane that will reward each play style best!

The stats are the same for the Secondary versions of the New Arcanes:

SECONDARY MERCILESS
On Kill:
+30% Damage for 4s. Stacks up to 12x.
+30% Reload Speed
+100% Ammo Max

SECONDARY DEADHEAD
On Headshot Kill:
120% Damage for 24s. Stacks up to 3x.
+30% to Headshot Multiplier.
-50% Weapon Recoil

SECONDARY DEXTERITY
On Melee Kill:
+60% Damage for 20s. Stacks up to 6x.
+60% Holster Speed.
+7.5s Combo Duration.

Ultimately each Arcane stacks up to the same amount of damage, but it’s how you choose to get there that counts. Precision? Spray and Pray? Melee synergy? Your choice!

The “Arcane Adapters themselves are an item you’ll need to install on the weapons you want to take further, and you can find the Primary and Secondary Arcane Adapters in the Steel Path Honors. The Arcanes themselves drop from Acolytes on The Steel Path.

• Removing the ability to Equip two of the same Arcane simultaneously.
• Added the ability to Distill assembled Arcanes back into multiple unranked ones.
• Arcanes that can trigger again while the Arcane is active are indicated in the Arcane Manager screen with a ‘Duration Can Refresh’ text.
• Arcanes will require 21 Arcanes to reach the new Max Rank of 5. Scarlet Spear will feature a buy-what-you-want shop for Arcanes based on the currency earned in the event. It will launch in March shortly after this Mainline.

Why: The reasoning here is mainly toward the ability to equip two of the same Arcane. This reasoning is one of past inconsistency and time determining intent. There are a lot of builds that specialize the use of two Arcanes, but we want to encourage a variety instead of duplication. Arcanes are the only Upgrade system in the game that allows two of the exact same upgrade to be equipped - and we would rather players have variety than duplications. In the same way you can’t equip Amalgam Serration and regular Serration, you can’t equip multiple Rivens per weapon, or any duplication of Mods at all, Arcanes will follow. But we are making major changes to the Ranking (up from 3 to 5 with power changes). Instead of having 2 of the same Arcane with a double effect, you can now choose between 2 different Arcanes that behave (generally) at 1.5x efficacy than before.

Fixes

• Fixed missing controller button callout to Rank up an Arcane in the Arcane Manager screen

Arcane System Overhaul

It’s been quite some time since we really dived back into Arcanes. Moving Arcanes to the Teralyst, Gantulyst and Hydrolyst was just the first step in a much bigger movement to improve the Arcane system that some Tenno might not even know exists.

If you need an Arcane refresher, this spoiler is for you!

View Arcane List▾▾

What is an Arcane?

Previously: Arcanes are Enhancements that can be installed on certain equipment and cosmetic items to grant them buffs that can be activated by achieving certain conditions within a mission.

Currently: Arcanes are Enhancements that can be installed on your Warframe, Operator, Operator Amp, or Zaw to grant them buffs that can be activated by achieving certain conditions within a mission.

How do I get an Arcane?

As of Hotfix 22.13.2 (2018-02-16), Arcanes are rewards from defeating the Teralyst, Gantulyst, and Hydrolyst in the Plains of Eidolon.

How do I view my Arcanes?

The Arcane Manager screen can be accessed by going to your Foundry and clicking the ‘ARCANES’ button on the bottom right of your screen.

How do I Upgrade my Arcanes?

Having multiple of the same Arcane will allow you to Upgrade it (similar to Mods). Upon accessing your Arcane Manager screen, you will see the button to Upgrade your Arcane and the stats included when it is Upgraded:

Choosing to Upgrade your Arcane results in consuming said Arcanes:

Your newly Upgraded Arcane will now display it’s Upgraded status and option to continue to Upgrade:

What’s New/Changed

• Upon logging in, all Arcanes installed on Cosmetics/Helmets will be Distilled because Arcanes can no longer be installed on Cosmetics/Helmets.
  • Old Legacy Arcane Helmets will keep their Arcane installed but you can not equip the Legacy Arcane Helmet on a Warframe with 2 Arcanes already installed.
• Arcanes can only be installed on your Warframe, Operator, Operator Amp, or Zaw.
  • You can install 2 Arcanes per Warframe Operator and 1 on your Operator Amp, or Zaw.
• You can now trade Upgraded Arcanes!
• Arcanes have received a visual overhaul! Arcane Rarity now matches the style we use on Mods and Relics. Hopefully this is a much clearer representation of their Rarity than before.

• You can now search/sort within the Arcane Manager screen.
• You must be at least Mastery Rank 5 or have an Arcane owned if below Mastery Rank 5 to install an Arcane.

Hotfix 22.13.4 (2018-02-22)

• Fixed Arcanes working inconsistently on Exalted Abilities (Excalibur’s Exalted Blade, etc) or Weapon Abilities (Titania’s Razorwing, etc).

Hotfix 22.13.2 (2018-02-16)

• Teralyst, Gantulyst and Hydrolyst now all drop Arcanes!
  • All 3 Teralysts have a 100% chance of dropping an Arcane.
  • The variety of Arcanes have been spread out across all 3 variants and weighted according to the rarity of the Arcane and difficulty of the Teralyst variant.
  • How you choose to defeat the Teralyst variants also attributes to the Arcane type/chance.
