Runescape Charming Moth is a Hunter Agility training method located in the Wilderness, east of the Green Dragon. To access this training method, you must have at least level 88 Hunter and level 83 Agility, both of which can be boosted. If you have access to Extreme Hunter Potions, you can access Charming Moth at level 78 Hunter, and stamina potions will allow entry at level 77 Agility. 

Using items that increase your catch rate, such as the Tracker Aura Super, Extreme Hunter Potions, the Volcanic Trap, and the Arctic Bear Pouch, will drastically increase your experience per hour. Additionally, the Ring of Metamorphosis has a 6% chance to double your experience gained. You can also use the Demonic Skull to increase your Hunter and Agility experience by 40%. Finally, using Decorated Hunter Urns and the Urn Enhancer will increase your experience per hour by 20-25%.

As of John Giggs' recent update, the Hunter and Agility experience gained from Charming Moth has decreased significantly. However, if you use the Demonic Skull, you will still get the same Hunter experience per hour as before. At level 90 Agility and without any boosts, you can get an estimated 208,000 Hunter experience per hour and 33,000 Agility experience per hour. With a high-level setup and the Demonic Skull, you can get up to 488,000 Hunter experience per hour and 73,000 Agility experience per hour. You can also expect to get 360-820 charms per hour with 10 being blue charms and 20 being crimson charms.

In conclusion, Charming Moth is still a great method of training Hunter and Agility and is still relatively AFK. However, the Agility experience gained is less than before due to the recent update. With the right boosts and equipment, you can still get a great Hunter experience per hour.
