What to bring to the Venomshank room
Bubonic Plant is Griefer’s transformed Chapter 2 finale: 40 base HP, 2 DEF, Mobile and level 2 Burn Weakness. It is immune to Poison. Choose a Burn source or attacks that perform well through defense instead of a Poison-based damage plan.
Venom Charge is your warning
Venom Charge applies Charged and Fast. Plant Rush follows the charge with sixteen hits and Poison. Treat the roar as the point to prepare protection, not an invitation to spend the last of your SP.
For ordinary attacks, Big Bite draws its head back before snapping. Tendril Flurry comes from the front and back after it burrows. Acid Rain sends five projectiles at distributed targets: follow the ball aimed at you rather than another party member’s impact.
Separate the charge from the normal rotation
The normal list is Big Bite → Tendril Flurry → Venom Charge → Acid Rain → Big Bite → Tendril Flurry. Plant Rush is the charged override. This is why merely memorizing Acid Rain as the next listed normal move will misread the dangerous turn.
Return fight
After Chapter 2, the rematch is in Toxic Nirvana. For the human-form fights and their different move lists, open the Griefer guide.
