The list is in the process OSRS GP of being completed. Start by starting daily warbands, slayering until you reach either 85 or 81 herblore. This is the stage that includes Chaos Dwarf Battlefield. AFK but requires the Forgiveness of a Chaos Dwarf Quest. Keep an eye out for beacons that can be used to collect loot. A clan chat or a friend chat may help. Although the beam lasts 10 minutes, the message that warns you about a beam will stay in the chatbox forever. Chat dialog may cause it to disappear. Beware of using degradables.
Frost Dragons; 3m an hour. It is possible to use ordinary anti-fires but food may be necessary. Try using a knife. This will require 85 Dungeoneering and possibly some magic notepaper.
Drygores aren't affordable without killing the QBD (or ascension) monsters (gladii or the roarii). Continue to build warbands until 96. Herblore is wise as well.
You can join a nex group or carry on QBD until you have at minimum 95 Prayer or 96 Herblore and other Tier 90 equipment. Skilling- Some people don't like killing things over and over, so I thought it would be a good idea to include this. Runecrafting. Runecrafting. Start at Runespan level 1. Continue training until you reach Runecrafting level 59. Craft double cosmic runes through the abyss. It can take up to 2m an hour. When you reach 82, you are able to craft two astral runes. This could be superior than cosmics, based upon the GE prices. At 91 you can create two natures. Check GE price once more to determine the most effective.
Herblore. Training buy runescape 3 gold normally, or daily warbands up to a certain level. Make unfinished potions (water and a herb) and then sell them. Crafting. Do Shades of Morton. Repair the temple using olive oil. 1m/hour, and very AFK
