Training your pure? Having trouble attacking a monk in that mostly over-populatated area? Don't feel like trying 20 worlds just to find an empty monastary? If your answer is yes, follow this guide.
First off, you need to know the location of monastary, where the monks are.
The blue line shows the ways from Varrock and Edgeville. The pink circle indicates your destination.
Now in this crowded area you may find it hard to attack or heal because it is a single-combat zone. These pictures should help you.
Now you can get those monks easily without worrying about other people.
All you have to do is attack the monks using the above paragraph. When you run low on HP, talk to the monk and select "I'm injured" and he will heal you. Have fun training!
