Comments;
-Cast Cos, kill some monsters and lay death sentries.
-Crushing blow is the heart of this build, so try not to have less than %40. Without cb this build has so very low dmg output.
-Even if you have max resists, do not hesitate to add on more as much as you can for it is possible stack up your resists beyond the max res cap even if it does not affect you damage intake. Yet this extra resists can save you in case you are attacked with conviction aura or lower resist etc. be it pvm or pvp.
