Vaykor Sydon

Polearm with a blocking-charged Radial Blind that is released by Block plus Heavy Attack.

Released Sep 15, 2016

Vaykor Sydon is a polearm with strong Puncture-weighted normal attacks and a special Radial Blind that charges as you block hits. Once fully charged, perform Block plus Heavy Attack to unleash it. Consider it when you can actively block and want the blind as a conditional utility effect; the charge requirement means the effect is not immediately available on demand.

Vaykor Sydon GUIDE

Understand Vaykor Sydon

Useful when…

  • Block hits to charge the Radial Blind, then use Block plus Heavy Attack when fully charged.
  • Use normal attacks for high Puncture damage and 33% status chance.
  • Use its 2.9 m range for polearm melee reach.

How does the Radial Blind work?

The stated sequence is to block hits to charge Radial Blind, then, when fully charged, use Block plus Heavy Attack to release it. Blocking is therefore part of the weapon's utility condition, not merely a defensive stance.

What are its normal and slam attacks?

Normal attacks deal 213 listed damage: 202.35 Puncture and 10.65 Impact, with 21% critical chance, a 2.5× multiplier, 33% status chance, and listed speed 1.08. Regular slams deal 426 Blast in an area with falloff to 7 m and 50% reduction; heavy slams deal 639 Blast with falloff to 8 m and 30% reduction. Heavy-attack damage is listed as 1,278, separately from the heavy-slam figure.

What investment considerations apply?

Vaykor Sydon requires Mastery Rank 11, has a rank cap of 30, and lists one Madurai polarity. Its 21% critical chance and 2.5× multiplier support considering critical investment, while 33% status chance and dominant Puncture also support other build choices. Its distinctive utility depends on blocking hits and triggering the charged move; it does not replace a freely available blind unless the charge condition is met.

How do the comparison weapons differ?

Sarofang creates a vortex with Heavy Slam at 8× combo, or 5× when wielded by Voruna. Caustacyst sends an acid wave on heavy attacks and leaves corrosive sludge. Dual Keres Prime is a dual-sword option with enhanced Heavy Attack Efficiency when Khora wields it. Their mechanics each have distinct conditions and do not share Vaykor Sydon's block-charged blind.

Limitations and tradeoffs

  • Radial Blind requires blocking hits to charge and a Block plus Heavy Attack input to release.
  • The required hit count and blind duration or radius are not specified.
  • Normal damage is heavily Puncture-weighted.

Common mistakes to avoid

  • Do not expect Radial Blind to trigger from ordinary attacks; it requires blocking hits and then Block plus Heavy Attack.
  • Do not assume a charge threshold, radius, or duration that is not specified.
  • Do not conflate the 1,278 heavy-attack figure with the 639 heavy-slam figure.
