I Got Lightning In My Veins

This is the Saradomin Swords Special Attack!  Lightning!  It does mass damage too.  The best I have ever hit with it so far has been a 40.  As I get stronger, the special gets stronger too.  The monsters I am fighting are called Ankou.  They are located on the 4th floor of the Stronghold of Security in Varrok.  They drop some wonderful stuff.  I always make around 100k every single trip down here.
