Mighty banshee

About
The Mighty banshee is first encountered in the quest Smoking Kills. It is basically a stronger version of the Banshee. Players must wear Masked earmuffs or a Slayer helmet when fighting them, or else your stats will be dangerously reduced by the banshees AND you will be damaged every few seconds by the swirling dust. As they have a magic-based melee attack, wearing dragonhide armour is suggested when fighting them. Be warned; they are in a Multi-combat area and are aggressive, however, there are some safe spots.

The Mighty banshee is an excellent source of pure essence. They drop 23 at a time, and very commonly. Approximately 1000 pure essence can be gained from killing 200 of them. Mighty Banshees also have a reliable drop rate of ranarr weeds (roughly a 1 in 17 chance).

Tactics
Using protect from melee and prayer boosting armour is a good way of killing Mighty Banshees. It is fast and effective, while a good money and experience earner. A Salve amulet (e) or Slayer helmet will raise the wearer's attack and strength by 20% and 15%, respectively. A Black mask, although giving the same attack and strength boost as the Slayer helmet, are not recommended due to the need of both earmuffs and a facemask - something only provided by the Slayer helmet or Masked earmuffs. These bonuses do not stack. A simple way to sustain your prayer for a bit longer is to use the Ancient mace special attack, which increses your prayer in accordance with what you hit in a ratio of 1:1.
