Requirements
Unlocks and practical targets

Provides a more forgiving learner experience.
Piety and sufficient prayer supplies improve consistency.
Prepare for the salt, mushroom, and poison process inside the arena.
Core mechanics
What controls the method
Poison preparation
Gather mushrooms and salt, process the ingredients, and apply both doses to wake Duke.
Extremities' gaze
Use cover and move when the wall eyes threaten the preparation lanes.
Gas vents
Read the vent pattern and avoid standing in the active gas area.
Melee rhythm
Attack in time with Duke and step back before the slam reaches your tile.
Slam attack
Treat the slam as a movement check, not a damage race. Reset your position before attacking again.
Enrage pace
Stay with the faster late-fight rhythm and avoid changing your cycle unnecessarily.

A practical operating loop
Prepare the arena
Gather ingredients while moving through the known safe lanes around eyes and vents.
Wake Duke from position
Apply the poison and begin where you can immediately establish the melee cycle.
Attack on rhythm
Use the same number of attacks between each required step-back.
Reset after every slam
Return to your chosen tile and rebuild the rhythm instead of clicking early.
Stay calm in enrage
Keep the pattern compact as the fight speeds up and finish with prayer and health in reserve.
Before you commit
How to use this guide
Preparation speed improves substantially once the arena path becomes automatic.
A consistent rhythm is more valuable than a theoretical max-damage setup while learning.
