That wont work, because templar need to use close range aoe forces. The refresh trick with lower crit only works if you are out of "cast" or hit range of the mob. If the mob is hit and not crit it will move to you or atk you if in range. If the mob already lost like 10-30% of their hp (not sure how much) and is not in atack or cast range it will cast refresh and then move to you. Also with not 100% crit chance there is always a chance that you fail more than 1 crit in a row and that can kill you xD But you can use lv7 crit buff (30 crit) + +5 sharp staff (35) + super crit potion (25) + aoe forces (10) you can get 100% crit chance without any sharp armor part.
