Hi all, i am dming my group(Barbarian, barb/thief, paladin and fighter) and they just cleared Greenest. They absolutely massacared every enemy i through at them(i even added some dragonclaws near Sanctuary) and the barb killed Langedrosa Cyanwrath. Of course not unscarred but damn. Therefore my question - how to balance future adventure against such a party? Replace all cultists with Dragonclaws and higher ranking cultists? Remove kobolds altogether? Does anyone have any similar experience? Thank you in advance.
