Incredibly high crit rate rate stacked with brutal momentum is a great combination. Invocation of Death reduces ability cooldown on critical hit which gives you a LOT of ability use. Lots of light attack spam and dodge dancing with this build.
Enduring Faith gives 50% toughness damage reduction on crit, combined with Benediction gives 65% damage reduction (pretty...pretty....pretty good). Because of Until Death you don't really need any extra wounds, but you can easily drop Anoint in Blood and Purge the Unclean at the top of the tree to grab Faith's Fortitude if you want.
