The exact wording is "This power counts as a ranged basic attack. So I'd say that was even more clearly in the "yes' column.It depends. I don't recall what the wording for Eldritch Blast and Magic Missile are.
Does it say they may be used "as ranged basic attacks" or that they may be used "when ____ calls for a ranged basic attack."
Former: Yes.
Latter: No.
