Parasite phases
Infested causes Phrog Parasite to summon Wrigglers when it dies. A single-target finisher that spends the whole turn can leave the player facing several new enemies without Energy or a useful hand. Include the spawned enemies when calculating the value of the kill.
If the Parasite is close to death, compare killing it immediately with entering the split on a hand that can attack the group. Delaying is not free: Infect adds pressure, and Lash hits several times. The useful choice depends on whether the better transition prevents more damage than the extra turn costs.
Repeated area attacks can reach the spawn
Dagger Spray damages every enemy twice. If the first hit defeats Phrog Parasite, the later hit can reach the Wrigglers that have appeared. Echoing Slash repeats its area attack after a kill, giving another way for the finishing play to continue into the new enemies.
This timing is more useful than treating every area card as equivalent. A one-hit area attack with no repetition may kill the Parasite without touching the newly created wave. Read the individual effect and count how many damage applications remain after the death.
Keep the new wave from attacking together
Once the Wrigglers appear, focus damage that actually defeats attackers. Partially damaging every enemy can leave the entire incoming attack active. A repeated area card or well-placed direct attack can instead remove several contributions before turn end.
Status handling matters if the encounter continues through another deck cycle. Discard or Exhaust can make an obstructed hand usable, but spending the last Energy only to improve future draws may leave the current Wriggler attacks unanswered.
