If you are going to burst these monsters, and you have a lot of money, I suggest you wear ancient robes or the kodai mage armor. The damage boost the skirt and the robe top give you add up quite nicely, and since you are attacking 8 at one you will see a decent increase in experience an hour. These robes are very expensive however, so for some people it is better to bring an alternative. Do not bring mystic or Ahrims if you can not afford Kodai mage armor. Due to the very low defense bonus these monsters have, you will not gain any significant accuracy when using magic to kill them. It is a much better idea to bring a prayer boosting armor. This way, you do not have to bring as many prayer potions for your protected melee, and you will be able to save an inventory spot for drops.
