Notes[edit | edit source]

  • One barrel blueprint is required to reach Rank 1 - Clearance: Agnesis with the Necraloid.
  • Initial 953 DmgToxinSmall64.png Toxin damage explosion will almost always be affected by headshot and headcrit bonuses, receiving double damage in addition to double critical multiplier.
  • Secondary projectiles from the initial explosion are affected differently by mods and buffing effects.
    • Damage from mods like Hornet Strike and Magnum Force apply to the 23 contact damage, but do not apply to the 333 DmgToxinSmall64.png Toxin explosion.
      • Spores randomly select targets within 20m of the host target. This range is not affected by Mod TT 20px.png Fulmination.
      • Spore contact damage has a guaranteed chance to proc DmgImpactSmall64.png Impact on secondary targets more than 7m away from the host target, but has 0% natural status chance to proc modded elements.
    • Elemental mods apply normally.
    • Faction Damage applies normally.
    • Multishot increases the number of initial projectiles, but not the 6 spores that are released from each explosion.
    • Critical Chance and Critical Damage bonuses are applied twice.
    • Flat Critical Chance Bonuses are applied twice. Once multiplied by modded critical chance, and again added last.
      • Critical Chance = 5% × ((1 + Modded Crit Chance) + Flat Crit Chance) × (1 + Modded Crit Chance) + Flat Crit Chance
      • Critical Damage = 2.3 × (1 + Modded Crit Damage)2
    • For example, with Mod TT 20px.png Cat's Eye, Mod TT 20px.png Pistol Gambit and Mod TT 20px.png Target Cracker, the secondary projectiles have:
      • Critical Chance: ((5% × (1 + Mod TT 20px.png 120%)) + Mod TT 20px.png 60%) × (1 + Mod TT 20px.png 120%) + Mod TT 20px.png 60% = 216.2%
      • Critical Multiplier: 2.3 × (1 + Mod TT 20px.png 60%)2 = 5.89x
    • Shooting the initial projectile through VoltIcon272.png Volt's ElectricShield130xDark.png Electric Shield or InfCrpShockSwarm.png Mutalist Quanta's Orbs will not affect the secondary projectiles.

Tips[edit | edit source]

  • Mod TT 20px.png Trick Mag in the Exilus slot will make up for the low maximum ammo.
  • Due to the nature of critical scaling, Critical mods are optimal despite the 5% base crit chance, and flat Critical Chance bonuses from HarrowIcon272.png Harrow's Covenant130xDark.png Covenant, Adarza Kavat's Mod TT 20px.png Cat's Eye, and ArcaneAvenger64x.png Arcane Avenger are further multiplied by modded critical chance.

Bugs[edit | edit source]

  • In multiplayer, poor to moderate network conditions can cause spores to never appear, despite landing headshots. Spore explosions also never occur regardless of network conditions.

Trivia[edit | edit source]

  • The Zymos was first seen and wielded by the Zealot Proselytizer in the third episode of Nightwave: Series 2 – The Emissary.
  • Depending on the level of the enemy (except for Infested enemies), upon performing a headshot, the enemy's head with swell up with an inflating noise before the spores explode.
