RuneScape- Easiest way to obtain a level 3 Clue Scroll

From my experiences,  I found out the best and the quickest way to obtaining a level 3 clue scroll is by killing Hellhounds.

Level : 122,127
Life point: 1150,1160
Attack style: Melee
Max hit: 118,130


Location : 

• Taverley Dungeon
• Witchaven Dungeon, lots of safe spots but requires the quest Family Crest. Only 2 spawns, and  very slow respawn time.
• Level 50-56 Wilderness

These are hunted for charms as well considering the drop rate of a charm is 89% which is very high, 60-65% being gold charms.
