Requirements
Access and practical preparation
Complete the firemaking portion that unlocks entry to the Ancient Cavern.
Keep an anti-dragon shield, dragonfire shield or dragonfire ward equipped with an antifire potion for the complete metal-dragon protection plan.
Mithril dragons use Magic and Ranged attacks in addition to melee and dragonfire, so choose the overhead prayer that covers the weaker defence in the selected setup.

Strategy
A practical step-by-step plan
Enter with the shield equipped
Use the whirlpool route into the Ancient Cavern and keep the selected wyvern or dragonfire shield on before a dragon can attack.
Choose the overhead for the setup
Mithril dragons use ordinary Magic and Ranged attacks in addition to dragonfire; protect against the style your armour handles least well.
Use dragonbane and enchanted bolts
Open with ruby enchanted bolts on a crossbow route, then switch to diamond enchanted bolts as the dragon's health falls.
Include Ancient Cavern travel
Bank before supplies or shield-protected inventory space run out and include the real cavern route in kills per hour.
Profitability and projections
The Wiki Estimate seeds loot and supply fields from current market inputs when available. Every assumption remains editable and your saved values take priority.
The calculator will update if the selected Wiki method provides a usable average loot value. You can enter your own value at any time.
Important drops
Notable rewards and drop categories
When the Wiki publishes a matching money-making method, its estimated average loot per kill is available in the editable calculator. Otherwise, enter your own verified sample.
What should I upgrade next?
Method-specific progression priorities
Rune crossbow -> dragon hunter crossbow
The dragonbane weapon is the main accuracy and damage improvement against the high-Defence target.
Anti-dragon shield -> dragonfire ward
The ward retains breath protection and improves the one-handed crossbow route.
Dragon hunter crossbow -> twisted bow
Treat the two-handed bow as a separate high-end setup using extended super antifire rather than pairing it with a shield.
Common mistakes
Avoidable causes of failed or inefficient trips
Ignoring dragonfire
Losing position during style choice
Mishandling banking distance: Count travel time when comparing the method with other dragons.
