Lesion GUIDE

Understand Lesion

Useful when…

  • Use its normal attacks when you want a Slash-heavy polearm with a substantial listed status chance.
  • Consider it when you can activate and make use of its blood-triggered Attack Speed and Toxin bonuses.

What changes after it tastes blood?

The weapon description specifies two conditional benefits: increased Attack Speed and increased Toxin Damage after it tastes blood. No duration, numerical bonus, or precise trigger mechanics are given, so those details should not be assumed. Its normal attack lists 237 total damage, chiefly 177.75 Slash, with 47.4 Impact and 11.85 Puncture; it has 37% status chance and 15% critical chance with a 2× critical multiplier.

How do its attack modes differ?

Normal attacks have 37% status chance. A standard slam is a separate Impact AoE attack with 474 listed damage and 10% status chance, with damage falling off to 50% by 7 m. A heavy slam deals Blast AoE damage, listed as 711, with 10% status chance and 30% falloff by 8 m. These slam values and statuses are not the normal attack profile.

What should you weigh against alternatives?

Lesion requires Mastery Rank 9. Harmony is a nearby mastery-range comparison at Rank 10, but its special condition is different: its heavy attacks condense Status Effect damage, and heavy-attack kills increase allies’ Status Duration. Fang has no Mastery requirement and is described as a fast dual-dagger weapon. Coda Pathocyst is a Rank 17 glaive that can spawn enemy-seeking miasmites. These are distinct mechanics, not direct upgrades to Lesion’s conditional polearm effect.

Limitations and tradeoffs

  • The blood-triggered benefits are not numerically specified.
  • The listed normal-attack damage is mostly Slash; slam attacks use separate Impact or Blast profiles.

Common mistakes to avoid

  • Do not treat the blood-triggered Attack Speed or Toxin bonus as a fixed numerical increase; none is supplied.
  • Do not apply normal-attack status chance to slam attacks, which list 10% status chance.
