Okay here are my stats: Strike: 40, Power: 40, Defence: 40, Hitpoints: 40, Mage: 40, Range: 30, Prayer: 25. Do I need to RuneScape gold train more or should I do dragon slayer now?
What to gather, 100monks, 10 prayer pots, 12 anti virus poison potions, and 10 super energies. For moving round the island bring two prayer potions (you may need it with the shield prayers you'll be wanting to use), 4 anti virus poison potions (really will need these), 1 superb energy (you do not want to run out of energy whilst crossing the road), and the remainder with meals. I propose bringing cammalot teliportation runes, in case you eat all of your meals, I saved me!
For the underground part, 4 prayer containers, 4 superb power potions, 2 anti virus poison potions, the things needed for the pursuit, and the rest with meals (if you maintain protect from mellee on the entire time, you will do fine). Keep an eye on your run, when it's about 50% drink a dose or two of operate energy, when prayer is at 28% beverage a prayer potion, eat when needed!
For the demon, one anti poison (for following the fight when you get teliported to the center of the jungle), camalot teliportation runes (for following the fight or when the demon somehow manages to remain alive:adorable:-RRB-, 4 prayer pots (over kill, but better safe then sorry), and the rest with good food. I propose bringing range gear (I used 10 mith arrows , at 61 ranging, I was tired of buy OSRS gold waiting, bring about 50 if you would like to terminate the fight quicker), along with a magic short bow! Anything that giving prayer and/ or magical defense is great!
