Tharros Lethality GUIDE

Understand Tharros Lethality

Useful when…

  • Use when you want Tharros Strike hits to apply the listed Critical Damage bonus to affected enemies.
  • Consider it with a Speargun, for which the listed bonus is doubled.

Effect and ranks

Enemies hit by Tharros Strike receive the listed Critical Damage increase: 25% at rank 0, 75% at rank 2, and 100% at rank 3. The listed bonus is doubled for Spearguns.

Who receives the bonus

The effect is described for enemies you hit with Tharros Strike. It is therefore tied to those hit enemies, rather than described as a general Critical Damage increase for all targets. No duration or refresh rule is specified.

Rank and mod fit

This Rare Styanax mod has Zenurik polarity, max rank 3, and base drain 6. Successive fusion examples list costs of 30, 60, and 120 Endo, plus 1,449, 2,898, and 5,796 Credits. Ranking raises the listed increase from 25% to 100%.

Other Styanax augment effects

Axios Javelineers spawns two Styanax Specters that throw javelins and create vortexes on impact; impaling an enemy increases vortex duration by 5 seconds. Intrepid Stand grants Styanax and allies within Affinity Range Overguard when Final Stand javelins damage enemies. These descriptions concern different abilities and effects from Tharros Lethality.

Limitations and tradeoffs

  • The listed effect applies to enemies hit by Tharros Strike.
  • The mod has base drain 6.

Common mistakes to avoid

  • Treating the listed percentage as a fully specified mechanical formula for modifying an enemy’s Critical Damage.
  • Assuming the bonus applies to enemies that were not hit by Tharros Strike.
