The Vaykor Sydon can be acquired by reaching the Rank of General with Steel Meridian, and spending 125,000125,000 to purchase. As with all Syndicate Weapons, the Vaykor Sydon cannot be chosen as the free offering upon ranking up to General rank.
The Vaykor Sydon requires 15 continuous blocked hits (ranged or melee) to fully charge its Radial Blind. The Radial Blind is activated once the block is released, and will blind enemies within a 15 meter radius for 5 seconds. Releasing the block by any means before the required number of charges has been reached will not activate the Radial Blind, along with resetting any acquired charges.
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.
Blocked attacks do not count when damage-nullifying abilities are active, such as Iron Skin or Warding Halo.
