Kao cen darach
Fisto is at a severe disadvantage since his form is weak against single opponents with single blades which that's what darach is going to be using and plus darach is a battlemaster and knows all seven forms but specializies in nymand so fisto will have to deal with those force attacks and when he went up against ventress he was beaten and the fight for darach is a good feat since he was able to go toe to toe with both Sith and take vindican out and vindican isn't featless he trained malgus who is noted as a very powerful sith so I wouldnt down play that feat
