Well,you mean at oly.
Buffs: ww,haste,last whisper,might,conversation.
You start with rsk. Focus blunt and angelic icon,you should be low hp and not using tol at beggin. When your hp is going down you use faith,when it goes down again, use TOL and change to sword. Try to be with FI and deal some more dmg.
But just2know,you cant kill a decent Domi. Your only hope is to make max dmg with your icons,cleanse his debuff if your pet is still alive,and keep your hp up by spamming sacri. If u manage to do that you may win by dmg.
