If you've visited the nightmare zone to RS gold improve the level of your afk experience, this section is ideal for you. To start off just go to one of the corners in the nightmare so that the bosses are unable to be able to reach you (remember you'll need melee bosses in order to make it work).
If you're planning to go for afk with your normal overload / absorption combo keep in mind that these effects can last roughly 5 minutes. There is also way that you can increase the duration to 20 minutes by using Super Combat potions in place of overloads. If you want to remain AFK for longer, it's possible to battle bosses on the easy mode using Guthan timer set to 20 minutes however it's not recommended since it wont give any gaming experience.
The most important part while training in nightmare environments is collecting points for both over- and absorption potions. You should be able purchase all of them each time you go into a dream. There's another method of using points to purchase items if you're close to reaching your cap. It should only be used once you know you will have enough points to purchase an upcoming batch of potions.
Firstly from NMZ you can purchase imbuables. Players can imbue any the fremennik and the wilderness ring to boost their stats two times. Black masks and Slayer helmet can be improved too adding to it 50 damage, and accuracy increases for magic and ranged also. Additionally, it is possible to impregn crystal objects to keep their maximum attack stats.
There is also special herb boxes that are available by using points. Each of these boxes includes different herbs and costs 9500 points. It is possible to purchase up to 15 boxes per day. be bought per day and OSRS buy gold each one contains herbs that are worth approximately 10k gold. This adds up to total 150k gold every day.
