PvP

Player vs. Player, colloquially shortened to PvP, refers to the collection of game types where player-controlled Tenno face off against each other in battle.

Duel
Dueling is a game mode added in Update 8 with the introduction of the Clan Dojo. By building a Dueling Room in the Clan Dojo, two players in that Dojo can begin a duel session. During the match, most of the effects and damage dealt by Warframe powers and Weapons remain the same as in missions.

Solar Rail Conflict
Solar Rail Conflicts is a game mode added in Update 14 which take place on Dark Sector nodes that are contested by another Clan or Alliance. This game mode allows a total of eight players compete in an asymmetrical attack/defense gamemode, where four players (supporting the Challenger) attempt to infiltrate and damage the Solar Rail while the other four (supporting the Occupant) defend it. Solar Rail Conflicts are currently disabled under the "Dark Sector Armistice" and will not return in their original form.

Conclave
Conclave is a Syndicate added in that provides large scale PvP missions. First introduced as a game mode in. It was restricted to players with similar Conclave Level instead of their clan affiliations, and features battles on designated arena tiles. The new Conclave introduced in Update 16 creates a new Arsenal for players with a limited number of Warframes and Weapons in order to allow fair play. Available game modes include Annihilation, Team Annihilation, and Cephalon Capture. Playing Conclave allows Tenno to earn Standing from Teshin, and unlock unique rewards as a result.

Limitations
 Conclave and Solar Rail Conflicts currently only allow certain Warframes and weapons to ensure balance is fair and even. Conclave-exclusive mods can be obtained from Teshin with Standing, from drops by Conculysts and Battalysts, and from completing a Conclave match. Unique variants, such as Prime, Wraith, MK-1, are generally permitted. All new pieces of equipment released since Update 16 are permitted.

Weapons

 * All weapons have their own unique stats in PvP that can be different from their regular stats, including damage, fire rate, and other stats.
 * Weapons cannot proc, however, some weapons will always proc on certain actions. These include:
 * Warframe abilities that always proc, such as Ember's Fireball and Volt's Shock.
 * Weapons that have innate elements, such as Detron or Heat Sword and Heat Dagger's slam attack.
 * Dread, which applies a two-second proc, each tick dealing three damage.
