Tips

  • Try to kill Red Louse quickly so it doesn’t accumulate too much Strength.
  • Punch it before it can Grow, or have enough block to absorb one Bite if needed.
  • If facing multiple Louses, focus on those growing Strength first to reduce damage escalation.

Trivia

Red Louse has the Curl Up power: it only activates once when taking its first damage each combat. On higher Ascensions, constraints are added to prevent repeated use of certain moves. :contentReference[oaicite:0]{index=0}
