Arcane Enhancement

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: 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. Common Arcanes are colored Bronze, Uncommon, Silver; Rare, Gold and Legendary Arcanes, Platinum.

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. Neither the duration nor the effects of the Arcane stack.

Stacking
Two Arcanes of the same type can be equipped together. They are divided into two categories:
 * 1) Arcanes whose effects change as they rank up:
 * 2) *E.g., ,
 * 3) *These Arcanes act completely independently of each other. Upon meeting their trigger condition, it is possible to trigger one, neither or both.
 * 4) **Either Arcane can trigger again, even while the other remains active or isn't triggered as well.
 * 5) **Note: The buff icon only displays the Arcane that triggered last.
 * 6) *For example, using two Rank 3 will result in a chance of 0.36 to trigger neither, 0.48 to trigger either and 0.16 for both to activate, in the last case providing +200% damage to secondaries.
 * 7) *The same rules apply for Arcanes of different ranks.
 * 8) **As lower ranked Arcanes have a lower buff duration (when applicable) they will obviously run out quicker if both were triggered at once.
 * 9) **Note: If the buff icon was shown for the shorter one, it will be removed from the UI even while the longer one remains active.
 * 10) Arcanes whose effects stay the same when ranked up:
 * 11) *E.g. or
 * 12) *Their trigger chance stacks additively.
 * 13) *For example, a Rank 1 and a Rank 2 (40% and 60%) together grant immunity to Magnetic procs as the combined chance to resist a proc is 100%.

Application
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 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. Arcanes can also be freely uninstalled without the use of an Arcane Distiller, or replaced by another Arcane without being destroyed in the process.

Rank
An Arcane can be ranked up by sacrificing duplicate Arcanes of the same type, granting up to four times the base effect in a single upgraded Arcane. Every successive rank-up requires one more Arcane than the last, depicted below. Up to 10 Arcanes in total are required to reach the maximum rank of 3.

Warframe Arcanes
Warframe Arcanes can be obtained by either killing or capturing Eidolon Teralyst, Gantulyst, and Hydrolyst, though capturing will yield more exquisite reward than simply killing it. For example, if Teralyst is simply killed, it will only yield common arcanes, but capturing it will yield a chance to drop the more uncommon ones.

Arcane Revives
Arcane Revives is a feature that is only gained from equipped Warframe Arcanes. Other types of arcanes such as Magus or Exodia do not benefit from this.

With each Rank 3 Warframe Arcane equipped, players will be able to revive their Warframes an additional time in a mission using an Arcane Revive, with a maximum total of 6 revives usable in a mission.

Magus Arcanes
Magus Arcanes affect the Operator or Warframe. Magus Arcane blueprints are purchasable from Quill Onko or Little Duck

Virtuos Arcanes
Virtuos Arcanes affect Amps. Virtuos Arcane blueprints are purchasable from the Quills and fully assembled from Vox Solaris.

Exodia Arcanes
Exodia Arcanes affect Zaws. Exodia blueprints are purchasable from Hok for Ostron standing upon reaching the rank of Kin, with the exceptions of Exodia Contagion and Exodia Epidemic, which are exclusive to Operation: Plague Star.

[1]For Contagion and Epidemic Arcanes, the effects may only be triggered after performing a double jump or bullet jump.

Pax Arcanes
Pax Arcanes are usable on Kitguns. Pax Arcanes are purchasable from Rude Zuud for Solaris United standing upon reaching the rank of Old Mate. Unlike other Arcanes, what players purchase are the actual Pax Arcanes, not their blueprints.
