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.

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 and is refreshable, the duration can be renewed by triggering it again.

A total of two Arcanes can be equipped on each Warframe, Operator, and Operator Amps (however, in the case of Warframes when an Arcane Helmet is used only a single Arcane can be equipped alongside). A maximum of one Arcane can be equipped on all weapons, while Zaw and Kitgun Arcanes occupy a unique slot separate from Primary/Secondary/Melee Arcanes. Archwing weapons have no Arcanes, and thus no slots.

They can be installed through their respective upgrade screens for the item. Arcanes can be upgraded in the Orbiter's Arcane Segment located between the Mod and Incubator Segments, which becomes available after acquiring an Arcane, or while equipping one in the Arsenal. 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.

Warframe's Exalted Weapons and Sentinel's Robotic Weapons cannot equip Primary, Secondary, or Melee Arcanes.

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:

Every successive rank-up requires one more Arcane than the previous one. The maximum rank of an Arcane depends on its type:

Following completion of the Whispers in the Walls quest, Loid offers his services for Arcane Dissolution. Unwanted Arcanes can be dissolved into Vosfor Vosfor which can be traded back to Loid in exchange for randomly selected Arcanes from a collection of choice. All collections cost Vosfor 200 and Credits64 50,000 to purchase.

Theorem Arcanes are Warframe Arcanes introduced in Update 29.5 (2020-11-19), obtainable from Arcana Isolation Vaults.

Molt Arcanes are Warframe Arcanes introduced in Update 31.5 (2022-04-27), obtainable from the Zariman Ten Zero.

Arcane Revives is a feature that is only gained from equipped Warframe Arcanes that is Rank 3 or higher. Other types of arcanes such as Magus or Exodia do not benefit from this. Each Arcane Revive equipped allows the player to revive their Warframe an additional time, with a maximum total of 6 revives usable in a mission.

Magus Arcanes affect the Operator and may provide benefits that also affect the Warframe. Magus Arcanes are purchasable from Quill Onkko and Little Duck. Following Update 24.6 (2019-04-04), Onkko and Little Duck both sell fully built Arcanes rather than Arcane Blueprints.

Emergence Arcanes are Operator Arcanes introduced in Update 31.5 (2022-04-27), obtainable from the Zariman Ten Zero.

This second arcane slot is initially hidden until the player has completed the Angels of the Zariman quest.

Virtuos Arcanes affect the Operator's Amps. Virtuos Arcanes are purchasable from The Quills and Vox Solaris.

Eternal Arcanes are Amp Arcanes introduced in Update 31.5 (2022-04-27), obtainable from the Zariman Ten Zero.

These arcane slots are initially hidden until the player acquires a Primary Arcane Adapter or is eligible to partake in The Steel Path. They also occupy their own spot that is separate from Kitgun's Pax Arcanes.

Longbow Arcanes are Bow-only Primary Arcanes introduced in Update 33.0 (2023-04-26), obtainable from Duviri.

Shotgun Arcanes are Shotgun-only Primary Arcanes introduced in Update 33.0 (2023-04-26), obtainable from Duviri.

Akimbo Arcanes are Dual Pistol-only Secondary Arcanes introduced in Update 33.5 (2023-06-21), obtainable from Duviri.

Unlike other Arcanes, these slots must be unlocked using MeleeArcaneAdapter Melee Arcane Adapter, which can be bought from the Market for Platinum64 20 or from Bird 3 of Cavia Syndicate Logo 1 Cavia for ReputationLarge 50,000 and requires Rank 3 - Colleague, or as a reward from Netracells or Deep Archimedia missions. Acquiring a Melee Arcane Adapter requires completion of the Whispers in the Walls quest.

Applying Melee Arcanes requires the Melee Upgrade Segment obtained from the Whispers in the Walls quest.

ARCANE DISSOLUTION

The Albrecht Laboratory is equipped with devices that can dissolve Arcanes into Vosfor, a potent powder for alchemical processes. It is used to trade for Arcane packs from a vendor in the Sanctum Anatomica!

The goal of Arcane Dissolution is to provide an alternative way for players to access and acquire the wide range of Arcanes found throughout Warframe.

HOW TO PERFORM ARCANE DISSOLUTION

Step 1: Speak with a vendor in the Sanctum Anatomica and select the “Arcane Dissolution” option to get started.

Step 2: Select the “Dissolve Arcanes” button

Step 3: Select the Arcanes you’d like to dissolve.

Step 4: Once you have chosen the Arcanes you’d like to Dissolve, hit the “Dissolve” button.

Step 5: Return to the Arcane Dissolution menu to exchange the earned Vosfor for a variety of Arcane packs.

ARCANE PACKS

The following Arcane Packs can be acquired from a vendor in the Sanctum Anatomica for Vosfor. Each pack is themed based on where their containing Arcanes are acquired.

Purchasing a pack will randomly reward 3 unranked Arcanes from their list. The possibility of a certain Arcane being selected is based on its rarity and respective drop rates through gameplay means. We want to maintain the integrity of its original acquisition methods in this new alternate way to access them.

ARCANE STAT CHANGES PER RANK

We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.

Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.

For example, using Arcane Fury.

This change mostly affects older Arcanes that don’t already fit this new formula (with the exception of Arcane Barrier*), as the majority of newer Arcanes already follow this system. The Arcanes listed below are formatted to showcase which stats have been changed from scaling to constant (with the old “Unranked” value in brackets), and which stats will still increase with rank, using the # / # format. For the sake of clarity, we are only sharing unranked and max rank stat values, not the incremental value changes for ranks between them.

*Arcane Barrier is the one true exception to the Arcane changes below, since it has two scaling stats, but one of those stats actually becomes worse with rank. Rank 3-4 for example increases the cooldown from 4s to 5s. So if we were to change it to have constant cooldown like the others, we would be increasing the cooldown duration for the lower ranks - which is something we want to avoid! Any other possible changes might have to alter how the Arcane works overall, so we ultimately decided to leave it untouched.

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.

Arcane Changes

After years of Arcanes as a system - with several additions to the offerings and replacement locations, we are doing several things:

View Arcane Changes List

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.

Now that we have returned to Cetus and the Plains of Eidolon with a remaster, we are applying some 'Economy Remaster' changes to go with the changes in an effort to apply our continued learnings. Change is the name of the game - thank you for all feedback on our economies and for being receptive to change!

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.
