I have figured it out and its as simple as adding a C# condition that looks like this. p.Name == ("insertnamehere")
So for those who use the Fight-class Creation tool, in the conditions drop down menu choose C sharp code then type into the value box p.Name == ("insertnamehere") and obviously insert the intended targets name in place of insertnamehere. The bot will only cast onto that target if its name matches this condition.
