Assume I have a multi-class paladin, and have spent a feat to take Avatar of Vice (from Heroes of Shadow) as my level 29 daily power instead of whatever my class power was. The last part of this ability reads:
If you start your turn with no uses available of your dread smite power, roll a d6. On a 5 or 6, you regain one use of that power.
If I don't have the dread smite power to begin with, will I gain that power regardless with a 5 or a 6 on a d6 roll at the start of my turn?
