his base damage is amazing and that health ratio is plenty enough of a nuke to make you feared... but if need be consider a wits end or sunfire ontop of your health one, the other, or both will get the job done for damage in total between synergising with his ulti and i agree on the trinity factor its not useful and its too expensive on voli its much better to get frozen mallet for added tankiness and ensured auto attacks during his ulti... as i look at it black cleaver isnt optimal on voli because he has so much more damage when speced into being more of a "on hit" sided champion like Irelia... also consider attack speed marks and quints (ad quints if realy need be) it realy stacks on from early to late game and you will almost always notice it as your getting much more out when you get your ulti up.. good luck with your ventures
btw i apologize for no grammar
edit: almsot forgot to tell you the nasus thing is probably his friggen attack speed slow... one does not simply 1v1 a nasus with a champion that relies on autos for damage
