Method-specific setups and tradeoffs

01MeleeBudget

Budget Melee

An affordable Melee setup focused on knockback counter at The Great Conch.

  • Arkan blade or dragon scimitar
  • Adamant full helm, platebody and platelegs
  • Tortugan shield in the cape slot
  • Granite shield or adamant kiteshield
  • Amulet of strength
Advantages+ Keeps the Shellbane Gryphon setup affordable+ Leaves room to prepare for knockback counterTradeoffs- Lower Melee damage than later Shellbane Gryphon tiers- Knockback counter can extend each kill
02MeleeRecommended

Recommended Melee

A repeatable Melee setup balancing damage with whirlwinds.

  • Zombie axe or abyssal whip
  • Granite helm, body and legs
  • Tortugan shield in the cape slot
  • Dragonfire shield or dragon defender
  • Slayer helmet (i) when the full setup remains at least 40 kg
Advantages+ Raises Melee damage against Shellbane Gryphon+ Practical for repeated trips to The Great ConchTradeoffs- Costs more than the Shellbane Gryphon entry loadout- Whirlwinds still needs the same response
03MeleeHigh-end

High-end Melee

Expensive offensive upgrades for sustained slayer boss farming after knockback counter is reliable.

  • Ghrazi rapier or Osmumten's fang
  • Bandos chestplate and Bandos tassets
  • Tortugan shield in the cape slot
  • Avernic defender
  • Black mask (i) or Slayer helmet (i) with at least 40 kg equipped
Advantages+ Cuts time spent on each Shellbane Gryphon kill+ Suited to frequent Shellbane Gryphon tripsTradeoffs- Highest purchase cost among the Shellbane Gryphon setups- Mistakes during knockback counter still cost supplies

Strategy

A practical step-by-step plan

1

Enter on a valid assignment

Complete Troubled Tortugans and fight on a gryphon task, a Shellbane boss task or the one-kill elite clue step.

2

Equip the tortugan shield

Wear the cape-slot shield and Protect from Melee so the gryphon's ordinary melee damage is fully blocked.

3

Verify 40 kg equipped

Check weight with an empty inventory; when the knockback stun appears, click the boss quickly to counter it.

4

Spread the whirlwinds

Move one tile between attacks so whirlwinds do not stack into a room-wide high-damage burst.

What should I upgrade next?

Method-specific progression priorities

1

Arkan blade or dragon scimitar → zombie axe or abyssal whip

Increase melee damage while retaining the required tortugan shield and at least 40 kg of equipped weight.

Major upgrade
2

Adamant armour → granite armour

The heavier armour improves defence while making the knockback weight threshold easier to meet.

Moderate upgrade
3

Dragon defender → Avernic defender

Use the offensive off-hand only after the rest of the worn setup still reaches the required weight.

Minor upgrade
Upgrade ROIEnter upgrade values to calculate

Common mistakes

Avoidable causes of failed or inefficient trips

Ignoring knockback counter

Losing position during whirlwinds

Mishandling ranged attack: Keep health available for the occasional Ranged hit while Protect from Melee covers the primary attack.
