Things to gather, 100monks, 10 prayer pots, 12 anti virus poison potions, and 10 super energies. For going around the island attract 2 prayer potions (you will need it with the shield prayers you will be wanting to RuneScape gold utilize ), 4 anti virus poison potions (really are going to want these), 1 superb energy (you don't want to run out of energy whilst crossing the road), and the rest with food. I suggest bringing cammalot teliportation runes, in the event you eat all your food, they saved me!
For the underground area, 4 prayer containers, 4 super power potions, 2 anti virus poison potions, the items needed for the pursuit, and the rest with meals (if you maintain protect from mellee on the entire time, you will do fine). Keep a watch out for your run, when it is around 50% drink a dose or two of operate energy, even when prayer is at 28% drink a prayer potion, consume when required!
For the demon, one anti poison (for following the battle if you get teliported into the middle of the jungle), camalot teliportation runes (for following the battle or if the demon somehow manages to stay alive:cute:-RRB-, 4 prayer pots (over kill, but better safe then sorry), and the remainder with great food. I suggest bringing variety gear (I used 10 mith arrows on him, in 61 ranging, I was bored of waiting, bring around 50 if you want to buy osrs gold safe end the fight faster ), and a magic brief bow! Anything that giving prayer and/ or magical defense is great!
