Signature Weapon

Signature Weapons are particular weapons associated with a specific Warframe or Companion, benefiting various advantages when wielded by its related character.

As of Update 24.6 (2019-04-04), Signature Weapons started to gain their own bonuses; before only the design and lore were related to their respective owner. The synergy varies from weapon to weapon and includes either a flat stat bonus (such as a flat Status Chance) or a new unique effect.

Notes

• Signature Weapons are also available in the market as part of their respective Warframe's Collection bundle including said Warframe and all the weapons associated. However, do note that not all Warframes having a Signature Weapon have their own Collection bundle. The Nidus Collection is the only exception as the weapons included aren't known to be his "Signatures".
• With the exception of  Euphona Prime and  Tekko Prime, Prime Weapons released with a Prime Warframe in Prime Access aren't known to be their "Signatures".
• Exalted Weapons are not considered Signature Weapons.

Trivia

• Although not explicitly labeled as Signature, Djinn's interaction with the  Gazal Machete was the first synergy Buff related to equipping two items together.
  • Signature Buffs related to Warframes and their Signature Weapons were introduced first with  Baruuk, then  Hildryn, before being extended to previously released Signature Weapons in Update 24.6 (2019-04-04).
• Some extremely important characters in the lore are known to have their own Signature Weapon such as the  Twin Grakatas of Clem,  Dread,  Despair, and  Hate of Stalker,  War of Shadow Stalker,  Paracesis of Ballas, or  Orvius of Teshin.
