Void Relic

"They say the contents of a Relic are simultaneously this thing, or this thing, or this thing, but also that thing and certainly never just one thing.

That is until it's exposed to a Void Fissure? And at that point, all the possibilities collapse, each one falling away until the Relic cracks open and exposes one, singular thing."

- Cephalon Ordis

Void Relics are Orokin objects that can be opened to reveal valuable treasure enclosed within by completing Void Fissure missions. They are the principal means of acquiring Prime and Forma Blueprints.

Acquisition
Void Relics are received as rewards in missions &mdash; primarily endless missions (although some non-endless missions, such as Spy, have a chance of rewarding a Void Relic upon completion). Void Relics packs can be acquired from Syndicates for standing, or from the Market. Void Relics can be traded between players.

As of all previously obtained Void Keys have been converted to Void Relics.

Use
One Void Relic at a time per player can be equipped for use in a Void Fissure mission, with a Void Relic selection screen appearing upon selecting a Void Fissure mission that allows a player to choose the desired Void Relic before starting.

Clicking on "Accept" when the fissure mission vote is started, will bring up the relic selection menu which will allow you to select a single relic for said mission. In endless missions, relics can be selected once for each rotation. This relic selection menu will offer exclusively relics of the era that matches the selected mission (example being, Lith relics for Lith era missions), and it will not allow refinement within it, so in order to refine relics, do so before accepting the mission vote.

Like Alerts, if the mission node where the Void Fissure is located has not been unlocked (completing the mission at least once), players will not be able to enter the mission and thus will not be prompted to equip a Void Relic.

If the mission is completed after cracking the Void Relic, followed by a successful extraction, each of the players' equipped Relics will display one of the potential rewards from their Relic's rewards table, with each player's reward being independent of their teammate's rewards depending on their equipped Relic and drop chance. All players with a Relic equipped can then choose which of the up to four rewards on offer they want to keep &mdash; either the one from their own relic or one from those of the other players.

After the rewards are chosen, the Relics equipped by all players are consumed. Relics that are not opened during the mission are not consumed.

Refinement


Each item in a Relic's reward pool is assigned a certain drop chance, which determines the likelihood of them being chosen after completing a Void Fissure mission, displayed by a blue bar in the Void Relic Refinement screen &mdash; the higher the bar, the higher the drop chance. These chances can be improved for rarer items through refinement.

Refined relics drop in endless Void Fissure missions. This occurs at every fifth opened relic. For example, Void Fissure Defense wave 25 gives a random Exceptional relic in addition to A-A-B-C rotation rewards, Wave 50 gives a random Flawless relic. Waves 75, and every 25 waves following that will give random Radiant relics. These refined relics do not cost Void Traces and are not listed in the rewards summary screen. They simply appear in inventory and are in addition to regular A-A-B-C rewards (which will be intact relics.)

To perform refinement themselves, players must complete the Mars Junction mission on Earth and install the Void Relic Segment they receive in their Orbiter. They must then collect Void Traces in Void Fissure missions, which are rewarded after collecting 10 Reactants in fissure missions.

With Void Traces, players can use the Orbiter's refinement function to upgrade a single Relic from "Intact" to "Exceptional" (25 Traces), "Flawless" (50 Traces), or "Radiant" (100 Traces). With each refinement tier, the chance for obtaining rarer items in the refined Relic's reward table is raised while the more common ones' chance is lowered.

After refinement, the newly refined Relic will be separated from the stack of Intact Relics. Only Intact Relics can be refined; Exceptional or Flawless Relics cannot be further refined to Flawless or Radiant.

Drop chances
Items within the same rarity have the same chance of being dropped from a relic. According to user datamining, refinement affects drop chances as follows, with the number in parentheses representing the chance of getting each specific item of that rarity: A group of 4 players with relics of the same refinement level has the following chances to obtain a rare item:

"Expected" refers to expected value; 4-player groups opening very large numbers of relics can expect to receive a rare item for each of this many relics used.

"90%" refers to confidence; a 4-player group looking for one rare item has a 90% chance to find it without using more than this many relics (but they might use fewer).

A group of four players with radiant relics has a 5.23% chance to receive two or more rare items; however, each player can keep only one. Using one relic at a time removes this possibility and may be worthwhile for getting the most out of rare or vaulted relics, but it does increase the expected number of runs required to find the item.

The rarity of a relic drop is indicated by the text color of its name: bronze (common), silver (uncommon) or gold (rare).

Ducat farming
Orokin Ducats are the currency required by Baro Ki'Teer for his unique items, and the only way to get Ducats is by opening Void Relics for Prime items and selling the Prime items for Ducats at the Relay kiosks.

Assuming that all relic drops can and will be traded for Ducats (i.e. no Forma and no items worth keeping), that no relic drops are valued inconsistently with their rarity (15 Ducats for common items, 45 for uncommon, and 100 for rare), and that in multi-player teams the rarest reward choice is always chosen, the expected number of Ducats to be earned per relic is as follows:

As shown, both refining relics and teaming up with other players vastly improve Ducat rewards. Playing in a team is free, but gathering traces to refine relics may be a less efficient use of time than simply opening more Intact relics if all you want is Ducats. If you do wish to maximize the use of traces, Exceptional relics offer the most Ducats per Void Trace spent.

Sale and trading
The Void Relics cannot be sold, but can be traded among players. In addition, the Prime components that are awarded from them have several uses:
 * They can be used to craft the respective equipment in the Foundry.
 * They can be traded for Platinum or other items to other players.
 * They can be traded for Ducats in a relay

List of Void Relics and drop sites
Relics are divided into four tiers, said to correspond to the eras of the Orokin empire. In ascending order of value, they are Lith, Meso, Neo and Axi. Each tier encompasses several types of relic, and each type has its own rewards table, comprising Forma blueprints, as well as Prime components and blueprints.

Vaulted Relics
Vaulted Relics are relics that contain vaulted items. When items are vaulted, all relics containing parts of these items are removed from drop tables while remaining in inventories.

There are currently 61 vaulted relics.

Relic Corruption
Upon opening a relic after collecting 10 reactant, your Warframe will experience a surge of void energy in the form of energy corruption. This corruption can be one of multiple possible buffs, lasting a set duration. The timer for the active duration of the buff is listed in the upper right corner next to your health bar.

The corruption effects are one of the following:
 * Your primary or secondary weapon no longer consumes ammo upon firing.
 * The Energy Cost of Melee Channeling is reduced to 1 unit of energy per hit.
 * Your Warframe's Ability Strength and Ability Range are doubled.

Void Relics
The are a total of 118 relics (unless some are missing) in the game taking into account the new ones that have been added recently in this month of February 2018.

there are total of.
