Notes[edit | edit source]

  • One barrel blueprint is required to reach the Rank of Clearance: Agnesis with the Necraloid.
  • Initial 953 Toxin b.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 26 contact damage, but do not apply to the 333 Toxin b.png Toxin explosion.
    • 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.pngCat's Eye, Mod TT 20px.pngPistol Gambit and Mod TT 20px.pngTarget Cracker, the secondary projectiles have:
      • Critical Chance: ((5% × (1 + Mod TT 20px.png120%)) + Mod TT 20px.png60%) × (1 + Mod TT 20px.png120%) + Mod TT 20px.png60% = 216.2%
      • Critical Multiplier: 2.3 × (1 + Mod TT 20px.png60%)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.pngTrick 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.pngCat's Eye, and ArcaneAvenger64x.pngArcane Avenger are further multiplied by modded critical chance.
