Comparing melee effects

Dreamer’s Wrath enables Tennokai and lists a critical-damage bonus for Tennokai attacks, while Flawed True Steel lists a critical-chance bonus. These describe different effects and conditions from Strain Infection’s critical-damage bonus per Cyst.

Limitations and tradeoffs

  • It uses a standard melee slot and has base drain 6.

Common mistakes to avoid

  • Reading the per-Cyst critical-damage bonus as critical chance.
  • Assuming a cap or specific Cyst count not given in the facts.
