Void Fissure



Void Fissures are a type of mission in which players can redeem Void Relics for treasure.

Access
At most times, one or two Void Fissure missions are available for each of the four tiers of Void Relics. Like alerts, they are associated with a normal mission node on the starchart, which must be unlocked to play the Void Fissure mission.

When entering a Void Fissure mission, players can equip a Void Relic of the appropriate tier. If they complete the mission, they can choose an item from their relic or another player's relic as a reward. If players have no relic equipped, they can complete the mission, but will not recieve any relic rewards.

Gameplay
In addition to its normal objectives, Void Fissure missions contain a Void Fissure – a floating orange flame – somewhere along the way between mission objectives.



Players may use their relic to trigger the fissure, which starts continuously spawning Orokin enemies. These enemies drop reactant, a glowing yellow substance, which players must pick up and deposit in the fissure by jumping through it. Fissure-spawned enemies also drop Void Traces, a resource used to refine Void Relics to make them drop rarer rewards, and to craft Dragon Keys.

The fissure closes after ten pieces of reactant have been dropped into it. This also kills any remaining Orokin enemies. Players have three minutes to close the fissure or the mission fails. However, every piece of reactant deposited in the fissure resets the timer.

After closing the fissure and completing the mission's other objectives, players may then extract as normal. At mission completion, they have 15 seconds to choose their rewards from their relics by double-clicking on the desired reward.

Tactics
Many Warframe abilities, notably field-based abilities such as Frost's Snow Globe, are effectively useless because the fissure spawns many Nullifier Crewman enemies, whose nullifier bubbles disable player abilities. Warframes who depend strongly on their abilities are therefore at a disadvantage.

Ember's World On Fire may be strong enough to kill enemies as they appear, especially on lower levels.

Bugs

 * After closing the fissure, the "Closing: 90%" message may remain visible on screen. This does not affect players' ability to complete the mission.
