"Gio's Hoes", nicknamed "Donor boss". Can be found by typing ::donorboss. The name of this place says it all, it is a donator boss ONLY. Therefore, you can ONLY fight against this boss when you have a donator rank In-Game. Many players kill this because of his famous EXP-lamp drops.
This isn't a very hard boss providing you have a fast hitting weapon such as some of the following; scoped Rifle,Assault rifle, space jam or an Ice katana. Once you have that, all you have to do is use your Prayers, in particular, "Soulsplit" which requires 92 prayer and this boss is super easy to kill.
