Are you trying to PK are not?
If so, i would get 99 range. If staking not needed.
What I will post is PK based. I don't know jack about staking.
First of all, stats:
Constitution: 80
Attack: 60
Strength: 96
Defence :1 (Sorry, no veng :/ )
Magic: 99
Prayer: 25 (I'm leaving mine at 11 but I'm not using D Claws);(now you could go 52 as said above, but I personally like having a lower combat)
Range: 99
Combat level: 73
Now, gear:
Head: Ghostly hood; CREAM HAT FTW

Neck: Glory
Body: Leather body; Ghostly robe top
Legs: Black d'hide chaps; Ghostly robe bottom
Hands: Adamant gloves (Recipe for Disaster reward)
Feet: Climbing boots (Death plateau reward)
Finger: Ring of life; ring of recoil
Back: God cape; obsidian cape
Weapon: Ancients staff, Rune crossbow or Magic shortbow, D claws or DDS (bring all three)
Offhand: Zamorak book
Bolts: Dragon bolts (e)
Risked wealth: about 50k (if not using D claws)
Now for the tactic:
1. Start out with ice barrage
2. Continue with either: if you think u can 1 shot him, by all means go for it with d claws. If not, whip out rune crossbow.
3: FINISH HIM!!! Rip him to shreds with your claws or DDS
4: Teabag him somehow
