The function of this build is to provide toughness boost and pushback for your allies at the expense of most of your damage. The way the build works is very simple. Your ultimate's cooldown is accelerated by all crits you land. The knife's base crit chance is higher than most weapons. "Blazing Piety" will add +25% crit chance, "Scourge" will add +30% crit chance, your weapon's perk will add +5%, and the "Smackdown" blessing will add 20%. The total crit chance above the knife's already high base crit is +80%. This means that even if you are not able to activate one or more of these, your crit chance should always be above 50%. The play cycle is incredibly simple. Activate your ult near your teammates. When it finishes, special-fire your knife for "Smackdown" and then spam left click. Kills are not your goal, so don't heavy attack while farming crits. In optimal conditions the ult (with a 60 second cooldown) can be cast ~10-15 seconds after it ends.
