Justice blinds. Block hits to charge a Radial Blind, when fully charged Block+Heavy Attack to unleash it.

The Vaykor Sydon is the Syndicate variant of the Sydon.png Sydon, available from Steel Meridian. It has the unique ability to store charges when blocking, which can be released as a RadialBlind130xDark.png Radial Blind once full by simultaneously blocking and performing a Heavy Attack while in full melee mode (default holding F ).




  • Normal Attack



  • The Vaykor Sydon can be acquired by reaching the Rank of General with Steel Meridian, and spending ReputationBlackx64.png 125,000 to purchase. As with all Syndicate Weapons, the Vaykor Sydon cannot be chosen as the free offering upon ranking up to General rank.
  • Syndicate weapons can be also be acquired via Trading, but only for unranked copies without Forma and Orokin Catalyst installed.
  • Players must have a Mastery Rank of at least 11 to acquire the Vaykor Sydon, either through trading or through the Syndicates themselves.


  • Blocking attacks with the Vaykor Sydon generates charges, up to 15. Once at 15 charges, Blocking and Heavy Attacking simultaneously consumes the charges to emit a RadialBlind130xDark.png Radial Blind, blinding enemies within 15 meters for 5 seconds.
    • The number of charges gained is displayed on the HUD beside the player's health as a Steel Meridian icon. The tip of the weapon also glows brighter as more charges are collected.
    • Attempting to Block+Heavy Attack without having 15 charges will perform the animation and consume the charges for no effect.
    • Blind radius is affected by (Mod TT 20px.png Primed) Mod TT 20px.png Reach.
    • Nullifier Crewman fields prevent enemies from being blinded.
  • Players gain bonus 50% chance to resist Knockdown or knockback when wielding the Vaykor Sydon.


  • When in a squad, using Mod TT 20px.png Guardian Derision allows players to attract aggro, making collecting charges easier.
  • Releasing the blind causes the player to momentarily stand still, similar to when ExcaliburIcon272.png Excalibur casts RadialBlind130xDark.png Radial Blind.
  • It's highly suggested to use a durable frame when planning on extensively using the Radial Blind feature.
  • The weapon's Radial Blind feature synergizes well with InarosIcon272.png Inaros' innate lifesteal as blinded enemies are opened up to finishers.


  • The concept for the radial blind effect of the Vaykor Sydon was designed by players Tourach and taiiat.
