🗺️ Walkthrough
Step-by-Step Execution Strategy
- 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).
- 2Phase 2: Kill demi-bosses (Dragon for Orb/Magic staff, Dark Beast for Bowstring/Ranged bow) to craft Tier 3 weapons.
- 3Phase 3: Cook 20-24 Paddlefish and brew 2-3 Egniol potions.
- 4Hunllef Boss Fight: Count attacks (Hunllef switches attack styles every 4 attacks). Switch prayers on attack 4.
- 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.
