🗺️ Walkthrough

Step-by-Step Execution Strategy

  1. 1Phase 1: Scout the perimeter rooms in a "C" shape to find resources (Linum Tirinum for cloth, Phren bark for wood, Grym leaves for potions, and ore).
  2. 2Phase 2: Kill demi-bosses (Dragon for Orb/Magic staff, Dark Beast for Bowstring/Ranged bow) to craft Tier 3 weapons.
  3. 3Phase 3: Cook 20-24 Paddlefish and brew 2-3 Egniol potions.
  4. 4Hunllef Boss Fight: Count attacks (Hunllef switches attack styles every 4 attacks). Switch prayers on attack 4.
  5. 5When Hunllef unleashes tornadoes, keep running on safe floor tiles (avoid the damaging orange/red grid).

🎯 Pro Efficiency Tips

  • Use the Tier 1 armor + Tier 3 weapons (Staff + Bow) prep method for the fastest 7-8 minute runs.
  • Staff has a fixed max hit regardless of your Magic level, making it extremely strong even at 80 Magic.

⚠️ Common Mistakes to Avoid

  • Losing track of Hunllef's 4-attack cycle and taking 50+ off-prayer damage.
  • Panic-running into floor lava tiles during tornado phase.
