Void Relics are received as rewards in missions — primarily endless missions (although some non-endless missions, such as Spy, have a chance of rewarding a Void Relic upon completion).
Endless Void Fissure missions grant pre-refined relics of ascending rarity for every fifth rotation reward (e.g. an Exceptional relic at 25 minutes of Fissure Survival, a Flawless relic at 50 minutes, and Radiant relics at 75, 100, and so on).
Elite Sanctuary Onslaught rewards relics pre-refined to Radiant.
Packs of 3 Void Relics can be acquired from Syndicates for 20,00020,000 standing, or from the Market.
Void Relics can be traded between players.
All existing Void Keys were converted into Void Relics or deleted at the launch of Update: Specters of the Rail, which included the rework of Prime part acquisition that introduced Void Relics to the game.
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 — either the one from their own relic or one from those of the other players. Note: Players can receive or choose any blueprint reward, regardless of the reward's Mastery Rank requirement to craft the item. Example: A player can choose and receive a Tigris Prime Blueprint at Mastery Rank 6, even when Tigris Prime requires Mastery Rank 13 to craft and use.
After the rewards are chosen, the relics equipped by all players are consumed. Relics that are not opened during the mission are not consumed.
When a Void Relic is successfully opened, exactly one of the six items in the relic is offered as a reward. Each item's chance of being chosen is represented as a blue bar in the Void Relic Refinement screen — the bar is not proportional to the item's probability of being chosen, but it does correctly rank items by probability and show decreases (for common items) and increases (for uncommon and rare items) as the player previews higher tiers of relic refinement.
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 10 Reactants in Void Fissure missions, which will coincide with a reward of Void Traces.
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.
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:
Chance for at least one rare item
Most players' relics, especially in public missions, will be either Radiant (from Elite Sanctuary Onslaught or self-refinement, best for finding specific uncommon or rare items) or, more likely, Intact (from almost every other source, best for ducat farming). This variant of the above table gives drop chances for most real squads.
Chance for at least one rare item
0 Radiant, 4 Intact
1 Radiant, 3 Intact
2 Radiant, 2 Intact
3 Radiant, 1 Intact
4 Radiant, 0 Intact
"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).
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 consoles.
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.
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.
"A", "B", and "C" refer to reward rotations. "✔" indicates a potential reward upon successful completion. "*" refer to Relics rewarded as Radiant.
Red text indicates that although a relic can drop from a given mission and rotation, the chance is very low (less than 2%). Hovering your mouse over a checkmark or letter will show a tooltip with the odds that a given reward will drop.
Baro Ki'Teer will occasionally sell relics containing exclusive (e.g. Aklex Prime) or otherwise vaulted items. Though these relics are not "vaulted" in the usual sense, Baro's stock changes every time he appears such that any given one of his items may be unavailable for months at a time.
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 Neo N7 Relic has been introduced into the mix to fix Nekros Prime Systems Blueprint being accidentally vaulted, and the Meso S6 Relic has also been introduced to fix Spira Prime Blade being accidentally vaulted.
