This list is not complete. Begin with daily warbands and then slayer to reach your target of 85 herblore/81 slayer. This stage includes the RS gold Chaos Dwarf Battlefield. AFK but requires the forgiveness of the Chaos Dwarf Quest. Loot beams should be checked regularly. It can be helpful to quit a clan chat or friends chat. The beam lasts for about 10 seconds however the message that alerts you to a beam is stored in your chatbox for a long time. However, chat dialogue could push it out. Beware of degradables.
Frost Dragons; 3m an hour. Normal antifires should suffice. But, you might need food. A stabbing weapon is an alternative. This requires 85 Dungeoneering, and possibly some magic notepaper.
You can't afford drygores if you don't kill the QBD (or ascension) monsters (gladii or roarii). It is recommended to continue with cheap RuneScape gold warbands that are up to 96 Herblore.
