• Strength bonus is preferred over prayer bonus for melee
• Inquisitor's armour provides an extra +2 prayer bonus over bandos making it slightly better if you are flicking correctly. Bandos has more defence to tank range hits without prayer.
• Melee with dragonhunter lance is similar dps to killing with blowpipe if you have a good strength bonus
• Learning the flame phase will speed up kills a lot

• Swap in a Serpentine Helm instead of Helm of Neitiznot / Royal if you have it.
• Swap out glory for Anguish / Fury if you have it.
• Dragon Bolt (e) as ammunition for the Runite Crossbow / Chaotic Crossbow.
• Replace Recoil for Wealth/Wealth (i) if you are able to kill before the snakelings spawn (Increases luck by 1-2%).
• Suggest Rune Darts/Dragon Darts for Blowpipe ammunition
• Auras/Relics are a GREAT help as well. Quickshot and Sharp Shooters being the best.
• A magic switch is recommended. Iban's blast can be an effective low level option, but a Trident of the Seas is recommended.
