Well it'll use up my special attack bar either with a DDS or a BGS, but after it uses it on an enemy it just stands there taking hits. I'll take a look at the debug console for you.
When the script is running it does everything fine at first, getting into the game it'll wait next to the knight and use all of my special attacks, afterwards equipping my Saradomin sword. After doing this the debug console reports, "Exception has occurred while running! Please report error to developer!"
Script works fine with no armour and a D Scimitar. My loadout consists of fighter torso, fury, warrior's helm, warrior's ring, combat bracelet, rune plate legs, and a Saradomin Sword. Currently finding out what bugs it.
