The easiest ones to eliminate are Man or Woman. It is also possible to RuneScape Gold kill Goblins or Cows in Lumbridge. It's clear that those enemies are not challenging in any way, which means it is possible to obtain scrolls without the effort. The drop rate is at or around 1 percent. You can therefore expect one scroll per 100 kills.
Easy Clue Scrolls - The easiest method to acquire them is through pickpocketing H.A.M. Members. The drop rate of scrolls should be in the range of 2%, which means that for every 50 pickpockets you'll get at least one scroll.
It also suggests you that Easy Clue Scrolls might be far easier to acquire than novice ones. While pickingpocketing H.A.M. Members, you could be exiled and taken out of their place of work Be sure to wear an H.A.M. set (which you can pick up from pickpocketing or buy it from Grand Exchange).
This will lessen the chance of getting removed from your farming location while pickingpocketing. If you do not have a high enough Thieving level or you do not want to use this approach, you can also purchase the imbued Ring of Wealth, head to the Edgeville Dungeon, and kill Thugs. They're monsters of level 10 So killing them shouldn't be difficult even for a new players. By wearing the ring you have a chance of 1/64 to receive the scroll after each killing.
Medium Clue Scrolls - Although they are named medium, they're harder to find than easy and beginner scrolls. The best method of farming Medium Clues involves fighting with Ice Warriors. They can be located in large quantities deep into the northwest Wilderness. They can easily be killed by Dwarf Multicannon and ranged attacks. Take note that going to Buy Old School RS Gold the Wilderness can be dangerous because of Player vs. player combat, so don't carry anything too valuable.
