Not so much.Sound of Azure said:Images can count as secondary targets, yes.
Nail said:Not so much.
The target must be a creature or object. The figments are neither.
For all intents and purposes, the figments from a foe’s
mirror image spell are your foes. You aim your spells and your
attacks at the figments just as though they were real creatures.
Any spell you can aim at a creature you can aim at an image.
When you use a spell that allows you to select multiple
creatures as targets, such as magic missile, you can choose
multiple images as targets.
