The best way 2 kill drangons is as follows:
Cast Magic resistance of ur drangon target (that is the blue spell magic resistance, there is a bug that means the spell sets magic resistance 2 20% even if it was higher than that in the first place
) Send in ur fighters 2 distract the dragon, whilst ur mages (U need at least 2) cast magic missile on him. I have 3 mages at level 12/14 all with minor sequenser which makes 30 missile a go! enough 2 level the most hardend of opponents.
