Nightblade

The Nightblade is a weapon used by the Shadow of the Sun clan. It is a huge weapon that does tremendous damage, but is also one of the slowest weapons in runescape. Due to its power, it is a very expensive weapon. It is slightly stronger than a godsword and is made by using darkness to merge with a claymore. Because of its huge size and weight, the user needs to have 60 strength along with 85 attack to wield it. Also, it gives a fairly high prayer bonus which is higher than most weapons.
