Our wizard cast a [Wall Of Fire](http://www.wizards.com/dndinsider/compendium/power.aspx?id=722) which is an implement power. 

* Does the damage that is caused when a creature starts their turn adjacent to or in the wall of fire get to add the implement's enhancement bonus?
* Does the bonus get added when a creature moves into the fire? If different from the question above, why?
* Is the bonus added during the wizards turn if the wall is created in the creature's square?
* Would it be different for any other sustained powers?
