Entral slicer is a weapon made by the Entrals. You can only get them by Level @ Treasure Trails. This weapon is strange because it gives defensive bonuses. It has a Special attack called "Spirit's Slice". It costs the user 1/4 of their health and prayer, but it drains all of your opponent's combat stats by half (including Constitution and Prayer). You raise the Entral Slicer, some wave of blood comes up to the air (that's the sacrifice), and then you do a well-aimed slice.
