Simple Q&A D&D 4e Thread 3

[MwaO]

The implication of the Rules Compendium (pages 214-215) is that you need to choose targets all at once (step 2, after choosing the power). But the same set of instructions seem to imply separate damage for all targets, when we know that there's only one damage roll on bursts/blasts, so it's a little unclear.

Except we don't actually know what they meant by 'making an attack' because there are 4 separate definitions...
